                              OPINION

WILKINSON, Chief Judge:

   Plaintiffs challenge a Bureau of Alcohol, Tobacco, and Firearms
("BATF") letter requiring federal firearms licensees to submit certain
record information to BATF. The district court held that the letter vio-
lated Section 106 of the Firearms Owners’ Protection Act of 1986, 18
U.S.C. § 926(a) (1994). RSM, Inc. v. Buckles, 94 F. Supp. 2d 692 (D.
Md. 2000). Because BATF’s issuance of the letter was limited to fed-
eral firearms licensees who had violated federal law in failing to com-
ply with firearms trace requests, we must reverse the judgment.

                                   I.

   Pursuant to the Gun Control Act of 1968, as amended, the Bureau
of Alcohol, Tobacco, and Firearms operates a firearms tracing system.
The system is designed to assist law enforcement agencies in criminal
investigations. A firearms trace typically begins when a law enforce-
ment agency submits a trace request to BATF after recovering a fire-
arm from a crime scene or from a suspect. BATF then tracks the
movement of the weapon through the chain of distribution to the fed-
eral firearms licensee ("FFL") who ultimately sold the firearm to the
retail purchaser. When BATF initiates a trace request, FFLs are
required to provide information such as the purchaser’s name,
address, and federal firearms license number. FFLs are also required
to respond to BATF trace requests within 24 hours. See 18 U.S.C.
§ 923(g)(7); 27 C.F.R. § 178.25a (2000).
                         RSM, INC. v. BUCKLES                           3
   In February 2000, BATF adopted new internal procedures because
some FFLs were not adequately complying with its trace requests.
First, BATF developed a definition of "uncooperative" FFLs. The
definition included those FFLs who, in 1999: (1) failed to respond to
a firearms trace request on at least one occasion; (2) failed to respond
to a trace request within 24 hours on three or more occasions; or (3)
provided incorrect information in response to a request. BATF then
issued "demand letters" to the 41 FFLs whom BATF deemed to be
uncooperative. The FFLs receiving these letters constituted less than
.1 percent of all the 80,000 FFLs nationwide. The letters required the
41 FFLs to submit information concerning their firearms purchases
and sales for the past three years, and on a monthly basis thereafter.
The information requested included a description of the firearms
including the models, serial numbers, and types, as well as the pur-
chasers’ names, addresses, and federal firearms license numbers.

   BATF saved the record information that it received from FFLs pur-
suant to its letters. With the exception of the purchaser’s name, BATF
also entered all the information into an electronic database. If BATF
determined that an uncooperative FFL had become cooperative,
BATF would destroy the hard copies of the record information. How-
ever, BATF continued to save the information in its electronic data-
base.

   On February 7, 2000, BATF issued a letter to RSM, Inc., d/b/a Val-
ley Gun of Baltimore ("Valley Gun"). BATF contended that Valley
Gun had repeatedly failed to comply in a timely manner with BATF
trace requests. In response, plaintiffs filed this action against the
Director of BATF seeking declaratory and injunctive relief. Plaintiffs
included Valley Gun, Valley Gun’s owner, and three anonymous indi-
viduals who lawfully purchased firearms from Valley Gun. Plaintiffs
alleged that the demand letter exceeded the scope of BATF’s statutory
authority and also violated their Fourth and Fifth Amendments rights.
In addition, plaintiffs claimed that the letter was invalid because it had
been issued by an official who lacked authority to do so.

   On April 13, 2000, after a bench trial, the district court perma-
nently enjoined BATF from seeking to enforce its letter. See RSM, 94
F. Supp. 2d at 697. The court found that RSM failed to timely comply
with trace requests on three or more occasions in 1999. Id. at 693 n.4.
4                            RSM, INC. v. BUCKLES
The court held, however, that the letter violated Section 106 of the
Firearms Owners’ Protection Act of 1986, 18 U.S.C. § 926(a). Id. at
696-97. BATF now appeals.

                                       II.

   Congress passed the Gun Control Act of 1968, Pub. L. No. 90-618,
82 Stat. 1213, to regulate interstate firearms transactions. See
National Rifle Ass’n v. Brady, 914 F.2d 475, 477 (4th Cir. 1990).
Among other things, the Act requires that importers, manufacturers,
and dealers of firearms obtain a federal license in order to operate.
See 18 U.S.C. §§ 922(a)(1), 923(a). Under the Act, the licensee must
maintain all records of firearms transactions as required by federal
regulation. The regulations are prescribed either by the Secretary of
the Treasury or the Secretary’s delegates, including BATF officials.
See 18 U.S.C. § 923(g).

   In December 1968, the Department of the Treasury issued regula-
tions designed to implement the Gun Control Act’s record keeping
requirements. In particular, section 178.126(a) requires licensees,
when requested by letter, to submit the relevant record information to
BATF. See 27 C.F.R. § 178.126(a).1

   In 1986, Congress enacted the Firearms Owners’ Protection Act,
Pub. L. No. 99-308, 100 Stat. 449 ("FOPA"), to amend several provi-
sions of the Gun Control Act. FOPA was intended to reduce the regu-
latory burden on law-abiding firearms owners without incapacitating
    1
     27 C.F.R. § 178.126(a) states, in relevant part:
        Each licensee shall, when required by letter issued by the Direc-
        tor of Industry Operations, and until notified to the contrary in
        writing by such officer, submit on Form 4483, Report of Fire-
        arms Transactions, for the periods and at the times specified in
        the letter issued by the Director of Industry Operations, all
        record information required by this subpart, or such lesser record
        information as the Director of Industry Operations in his letter
        may specify.
  Section 178.126(a) originally used the term "Assistant Regional Com-
missioner" instead of "Director of Industry Operations." The current reg-
ulation is otherwise identical to the version prescribed in 1968.
                            RSM, INC. v. BUCKLES                             5
BATF’s ability to combat violations of the firearms laws. See Brady,
914 F.2d at 477. Two provisions of FOPA are relevant to this case.
First, FOPA enacted section 923(g)(5)(A), which essentially codified
17 C.F.R. § 178.126(a). See 18 U.S.C. § 923(g)(5)(A).2 Like the regu-
lation, section 923(g)(5)(A) obliges each federal firearms licensee,
when required by letter, to submit record information to BATF. See
id.

   Second, FOPA amended section 926(a) to limit the Secretary’s
ability to pass regulations creating a registry of firearms. See 18
U.S.C. § 926(a).3 The amendment provides that BATF may not pre-
scribe any "rule or regulation" after the enactment of FOPA requiring
firearms records to "be recorded at or transferred to a facility owned,
managed, or controlled by the United States." Id. The amendment also
prevents BATF from prescribing rules or regulations which require
"that any system of registration of firearms, firearms owners, or fire-
arms transactions or dispositions be established." Id.

  2
   18 U.S.C. § 923(g)(5)(A) provides, in relevant part:
     Each licensee shall, when required by letter issued by the Secre-
     tary, and until notified to the contrary in writing by the Secre-
     tary, submit on a form specified by the Secretary, for periods and
     at the times specified in such letter, all record information
     required to be kept by this chapter or such lesser record informa-
     tion as the Secretary in such letter may specify.
  3
    18 U.S.C. § 926(a) provides, in relevant part:
      The Secretary may prescribe only such rules and regulations as
      are necessary to carry out the provisions of this chapter. . . . No
      such rule or regulation prescribed after the date of the enactment
      of the Firearms Owners’ Protection Act [May 19, 1986] may
      require that records required to be maintained under this chapter
      or any portion of the contents of such records, be recorded at or
      transferred to a facility owned, managed, or controlled by the
      United States . . . nor that any system of registration of firearms,
      firearms owners, or firearms transactions or dispositions be
      established. Nothing in this section expands or restricts the Sec-
      retary’s authority to inquire into the disposition of any firearm in
      the course of a criminal investigation.
6                       RSM, INC. v. BUCKLES
                                 III.

                                  A.

                                  1.

   Plaintiffs’ principal argument is that BATF’s letter exceeds the
scope of its authority under section 923(g)(5)(A) and violates the lim-
itations set forth in section 926(a).

   Section 923(g)(5)(A) grants BATF some limited amount of author-
ity to secure record information from FFLs. See 18 U.S.C.
§ 923(g)(5)(A). That provision states:

    Each licensee shall, when required by letter issued by the
    Secretary, . . . submit on a form specified by the Secretary,
    . . . all record information required to be kept by this chap-
    ter.

Id. Likewise, 27 C.F.R. § 178.126(a) recognizes BATF’s authority to
issue letter requests. That regulation provides:

    Each licensee shall, when required by letter issued by the
    Director of Industry Operations, . . . submit on Form 4483,
    Report of Firearms Transactions, . . . all record information
    required by this subpart, or such lesser record information
    as the Director of Industry Operations in his letter may spec-
    ify.

   BATF contends that unless some other statutory provision narrows
the scope of 18 U.S.C. § 923(g)(5)(A) and 27 C.F.R. § 178.126(a),
these provisions would permit BATF to issue the letter in this case.
Plaintiffs suggest several possible limitations. Their primary argument
is that BATF’s demand letter violates section 926(a)’s prohibitions
against the transfer of firearms records to a federal facility and the
establishment of "any system of registration of firearms." 18 U.S.C.
§ 926(a).

  By its plain text, however, section 926(a) does not directly limit
BATF’s authority under either 18 U.S.C. § 923(g)(5)(A) or 27 C.F.R.
                          RSM, INC. v. BUCKLES                            7
§ 178.126. Section 926(a)’s prohibitions apply only to a "rule or reg-
ulation prescribed after the date of the enactment of the Firearms
Owners’ Protection Act." 18 U.S.C. § 926(a) (emphasis added). Sec-
tion 923(g)(5)(A) is a statute, not a rule or regulation. Likewise, while
27 C.F.R. § 178.126 is a regulation, it was prescribed in 1968, long
before the enactment of FOPA in 1986.

   The district court was cognizant of this fact but believed that BATF
had never before interpreted the regulation to permit BATF to issue
letters such as those in this case. See RSM, 94 F. Supp. 2d at 696.
BATF in turn presented substantial evidence that it interpreted 27
C.F.R. § 178.126 to permit it to issue letters to noncompliant FFLs as
far back as 1968. However, this dispute does nothing to change the
fact that section 926(a)’s limitation is triggered by the date on which
the rule or regulation was "prescribed." See 18 U.S.C. § 926(a).
Because 27 C.F.R. § 178.126 was prescribed in 1968, and because the
regulation grants BATF authority to issue the letters regardless of
whether BATF has previously exercised that authority, section 926(a)
does not directly foreclose BATF’s authority to issue the letter. How-
ever, as discussed below, the statute does not grant BATF an
unbounded delegation of authority to request record information.

                                    2.

   Plaintiffs next argue that section 923(g) requires BATF letters to
be in relation to a bona fide criminal investigation. They contend that
since BATF’s letter to Valley Gun is not required for determining the
disposition of firearms in the course of a particular criminal investiga-
tion, the letter is invalid. To support their interpretation of the statute,
plaintiffs point to section 923(g)(7), which requires FFLs to respond
within 24 hours to a request for record information "as may be
required for determining the disposition of 1 or more firearms in the
course of a bona fide criminal investigation." 18 U.S.C. § 923(g)(7).

   Section 923(g)(7), however, does not automatically prevent BATF
from issuing such letters under section 923(g)(5)(A). Section
923(g)(7) does not purport either to address or restrict BATF’s section
923(g)(5)(A) authority to issue letters. Instead, it establishes the
duties of FFLs when they receive a trace request. There is no dispute
that the trace requests BATF originally submitted to Valley Gun were
8                        RSM, INC. v. BUCKLES
"in the course of a bona fide criminal investigation." See 18 U.S.C.
§ 923(g)(7). Valley Gun cannot invoke its failure to comply with
those original requests as a reason for limiting BATF’s separate
authority to issue a letter under section 923(g)(5)(A).

   Plaintiffs also point to section 923(g)(1)(B). That section autho-
rizes the Secretary to physically inspect FFLs’ records "when such
inspection or examination may be required for determining the dispo-
sition of one or more particular firearms in the course of a bona fide
criminal investigation." 18 U.S.C. § 923(g)(1)(B)(iii). BATF’s
authority to issue a letter under section 923(g)(5)(A), however, is not
per se foreclosed by section 923(g)(1)(B)’s prohibition on inspecting
records. The statutory scheme makes clear that section 923(g)(1)(B)
is aimed at preventing warrantless, on-site searches of FFLs’ records.
In contrast, issuance of a letter under section 923(g)(5)(A) does not
involve the entry of BATF agents onto an FFL’s premises. Rather, it
requires FFLs to send certain information contained in their records
to BATF.

                                    3.

   While the above provisions cited by plaintiffs do not directly pro-
hibit BATF’s issuance of the letter in this case, it is equally clear that
section 923(g)(5)(A) is not a limitless delegation of authority to
BATF to request record information. Section 923(g)(5)(A) does not
explicitly state the purposes for which the Secretary may issue letters.
Other provisions of the statute, however, make clear that section
923(g)(5)(A) cannot be construed in an open-ended fashion. For
instance, section 923(g)(1)(A) provides that FFLs "shall not be
required to submit to the Secretary reports and information with
respect to such records and the contents thereof, except as expressly
required by this section." 18 U.S.C. § 923(g)(1)(A) (emphasis added).
Section 923(g)(1)(A)’s express limitation on the Secretary’s authority
would be nullified if section 923(g)(5)(A) were interpreted to permit
the Secretary to issue demand letters for any purpose. Likewise, while
section 926(a) does not directly prohibit BATF’s issuance of the letter
in this case, that provision clearly demonstrates Congress’ concern
about any attempt by BATF to establish a national firearms registry.
Section 926(a) would be rendered meaningless if BATF could issue
limitless demand letters under section 923(g)(5)(A) in a backdoor
                        RSM, INC. v. BUCKLES                          9
effort to avoid section 926(a)’s protections for law-abiding firearms
owners. Congress clearly did not intend such a result.

   It is unnecessary in this case, however, to delineate the precise
scope of BATF’s authority to issue letters to FFLs. Our holding here
is a limited one. In this case, BATF issued its letter in response to
findings that a small number of FFLs were routinely failing to comply
with lawful BATF trace requests in criminal investigations. BATF
narrowly-tailored the request to its tracing needs by issuing the letter
only to the .1 percent of FFLs nationwide who failed to comply with
statutory trace requests. See 18 U.S.C. § 923(g)(7). In addition, BATF
will terminate these 41 FFLs’ obligations once they comply with fed-
eral law and cease to hamstring BATF’s criminal investigations.
Nothing in the relevant statutory framework suggests to us that letters
which are narrowly-tailored to facilitate BATF’s trace-request author-
ity in criminal investigations run afoul of BATF’s authority under
section 923(g)(5)(A) to issue appropriate requests for record informa-
tion. While we are not free to ascribe to section 923(g)(5)(A) an open-
ended reach, neither are we at liberty to eliminate altogether its posi-
tive grant of authority.

                                  B.

   Plaintiffs further contend that section 923(g)(5)(A) is restricted by
an appropriations rider to Pub. L. No. 106-554, 114 Stat. 2763 (2000).
The rider prohibits the expenditure of appropriated funds for salaries
or administrative expenses "in connection with consolidating or cen-
tralizing, within the Department of the Treasury, the records, or any
portion thereof, of acquisition and disposition of firearms maintained
by Federal firearms licensees." Pub. L. No. 106-554, 114 Stat. 2763
(2000). The rider has been reenacted annually since 1978. It was first
passed in response to a proposed BATF regulation which would have
required all FFLs to submit a quarterly report of all of their firearms
dispositions. See 43 Fed. Reg. 11,800-02 (March 21, 1978). Congress
was alarmed by BATF’s attempt to secure the records of all FFLs
nationally and the accompanying invasion of lawful firearms owners’
privacy. Id. Plaintiffs propose that the appropriations rider now be
read broadly to serve as an absolute prohibition against any collection
of firearms records.
10                      RSM, INC. v. BUCKLES
   Congress has amended the Gun Control Act several times, most
notably with FOPA, since it originally passed the appropriations rider
in 1978. See, e.g., FOPA, 100 Stat. at 449 (1986); Violent Crime Con-
trol and Law Enforcement Act of 1994, Pub. L. No. 103-322, 108
Stat. 1796, 2013. Were we to adopt plaintiffs’ view of the rider, it
would render several provisions of FOPA inoperative. See Colautti v.
Franklin, 439 U.S. 379, 392 (1979) (it is an "elementary canon of
construction that a statute should be interpreted so as not to render
one part inoperative"). When it passed FOPA, Congress clearly envi-
sioned some sort of collection of firearms records, so long as it was
incidental to some other statutory function specifically delegated to
BATF. For example, some small collection of records occurs when
FFLs comply with 18 U.S.C. § 923(g)(3)(A) by forwarding to BATF
reports of multiple firearms sales to an unlicensed individual. Like-
wise, some collection of records occurs when FFLs who are closing
their businesses comply with 18 U.S.C. § 923(g)(4) and forward their
records to BATF.

   As with these examples, some limited collection of records occurs
when BATF issues a letter to FFLs who have not complied with
BATF’s trace requests. In such cases, the collection of information is
directly tied to BATF’s statutory tracing function. It is a very far cry
from the creation of a national firearms directory. The letter here was
issued under 18 U.S.C. § 923(g)(5)(A), and then only to the .1 percent
of FFLs nationwide who failed to cooperate with BATF’s gun trace
requests under 18 U.S.C. § 923(g)(7). There is no evidence that the
letter served as a ruse to avoid FOPA’s prohibition against the cre-
ation of a national firearms registry. In light of the narrow scope of
the demand letter and its direct relationship to BATF’s explicit statu-
tory duties to conduct trace requests in particular criminal investiga-
tions, there was no statutory violation.

                                  C.

   Plaintiffs also argue that the letter was invalid because it was
issued by the National Tracing Center, which allegedly lacked author-
ity to do so. The Secretary of the Treasury properly delegated his
authority to administer 18 U.S.C. § 923(g)(5)(A) to BATF’s Director
of Industry Operations. See 27 C.F.R. § 178.126(a). In an internal
memorandum, the BATF Director further delegated this authority to
                         RSM, INC. v. BUCKLES                          11
the National Tracing Center. Plaintiffs contend that this subsequent
delegation was improper because the Director’s memorandum was a
"rule or regulation" subject to the notice-and-comment rulemaking
requirements of section 926(b). See 18 U.S.C. § 926(b) (stating that
before prescribing rules and regulations the Secretary must notify the
public and provide an opportunity for a hearing).

   BATF is not required, however, to engage in notice-and-comment
rulemaking in order to internally delegate its authority. Section 926(b)
does not define the term "rule or regulation." Plaintiffs suggest that
section 926(b) implicitly incorporated the Administrative Procedure
Act’s (APA) broad definition of the term. See 5 U.S.C. § 551(4).
Even assuming the memorandum would qualify as a rule within the
meaning of the APA, however, the APA provides that "rules of
agency organization, procedure, or practice" are exempt from the gen-
eral notice-and-comment requirements of section 553. See 5 U.S.C.
§ 553(b)(A). The exception applies to "agency actions that do not
themselves alter the rights or interests of parties, although [they] may
alter the manner in which the parties present themselves or their view-
points to the agency." JEM Broadcasting Co. v. F.C.C., 22 F.3d 320,
326 (D.C. Cir. 1994) (internal citations omitted); see also City of
Alexandria v. Helms, 728 F.2d 643, 647-48 (4th Cir. 1984) (holding
that notice-and-comment rulemaking is required only if the rule
"makes a substantive impact on the rights and duties of the person
subject to regulation"). To the extent that Congress intended section
926(b) to incorporate the APA’s definition of "rule," there is little rea-
son to believe that it did not also intend to incorporate the APA’s
exception for "rules of agency organization, procedure, or practice."
See 5 U.S.C. § 553(b)(A).

   Here the delegation to the National Tracing Center did not alter any
of plaintiffs’ substantive rights. Valley Gun was already on notice that
it would have to respond to letters when requested by the Secretary
or his delegates to do so. See 18 U.S.C. §§ 923(g)(5)(A) &
921(a)(18). Rather, the delegation merely affected which BATF agent
would issue the letter. BATF need not engage in notice-and-
comment-rulemaking each time it delegates authority within its own

   Plaintiffs finally contend that the issuance of the letter was an
unreasonable search and seizure under the Fourth Amendment.4
BATF’s letter is analogous to an administrative subpoena. The
requirements for enforcing an administrative subpoena "are not oner-
ous." United States v. Sturm, Ruger & Co., 84 F.3d 1, 4 (1st Cir.
1996). The Fourth Amendment requires simply that administrative
subpoenas for corporate books or records must be "sufficiently lim-
ited in scope, relevant in purpose, and specific in directive so that
compliance will not be unreasonably burdensome." Donovan v. Lone
Steer, Inc., 464 U.S. 408, 415 (1984) (quoting See v. City of Seattle,
387 U.S. 541, 544 (1967)). BATF’s letter satisfies these requirements.
Both 18 U.S.C. § 923(g)(5)(A) and 27 C.F.R. § 178.126(a) grant
BATF authority to issue letters. Furthermore, the letter specifically
informed its recipients what information BATF required. In addition,
an FFL’s obligation to provide record information to BATF will
expire once the FFL has assured BATF of future compliance with
statutory trace requests. Finally, an FFL has recourse against an
unreasonably burdensome letter by raising objections to it in a district
court before suffering any penalties for noncompliance. See Lone
Steer, 464 U.S. at 415.

                                  IV.

   Whether the investigative benefits of BATF’s requests for informa-
tion outweigh the reporting burdens is a matter for legislative judg-
ment. The statutory mission is for Congress to set forth, and the
potential for abuse is for Congress to proscribe. It is clear that Con-
gress did not intend to give BATF carte blanche with regard to infor-
mational requests from federal firearms licensees. However, BATF’s
letter in this case was narrowly tailored to a specific grant of positive
statutory authority.

   Plaintiffs also raised a Fifth Amendment claim in the proceedings
below, arguing that the demand letter subjected Valley Gun to punish-
ment without due process of law. Plaintiffs’ brief fails to mention the
Fifth Amendment claim, however, and in all events there is no Fifth
Amendment violation.

  For that reason, the judgment is reversed and the injunction
vacated.
