                              OPINION

PER CURIAM:
   Aubrey Moore, III appeals from his sixty-three month sentence and
court-ordered child support payments imposed following his guilty
plea to one count of possession of a machine gun in violation of 18
U.S.C.A. § 922(o) (West 2000). Moore challenges the constitutional-
ity of 26 U.S.C.A. § 5845(b) (West 2000), which defines "machine
gun" for the purposes of § 922(o). Our review of the record discloses
no reversible error with regard to the conviction. However, the district
court erred in requiring payment of past child support obligations as
a part of the sentence. Therefore we affirm Moore’s conviction and
sixty-three month sentence, but vacate the district court’s order to pay
child support.
   We find that the definition of a receiver of a machine gun under
§ 5845(b) satisfies Due Process. Vagueness challenges not threaten-
ing First Amendment interests are examined as applied to the facts of
the case. Maynard v. Cartwright, 486 U.S. 356, 361 (1988). Accord-
ing to the Firearms Technology Report, openings for the bolt handle
slot, magazine port, ejection port, and sear had been cut out of a pipe
seized from Moore’s residence. Although the openings had not been
filed down to final specifications, the slots and openings were prop-
erly located and consistent with the slots and openings on a Sten
machine gun. Section 5845(b) includes any part designed and
intended for use in converting a weapon into a machine gun. Moore’s
part is clearly a receiver within the statutory definition.
   Regarding Moore’s claim that he was improperly sentenced, we
find no statutory authority to impose back child support payments for
this offense and vacate this portion of the district court’s order. We
dispense with oral argument because the facts and legal contentions
are adequately presented in the materials before the court and argu-
ment would not aid the decisional process.
                         AFFIRMED IN PART; VACATED IN PART
