Before MURPHY, BYE, and SMITH, Circuit Judges.
                           ___________

SMITH, Circuit Judge.

      Mark Backer appeals from a decision of the district court resentencing him
from 60 to 87 months' imprisonment. We consider whether plain error occurred and
deciding that it did we remand for sentencing in conformity with United States v.
Booker, 

(2005).


                                  I. Background
     A confidential source told the Mandan City Police Department that Mark
Backer owned a shop where there was frequent drug dealing. Officers executed a
search warrant at Backer's residence. Roger Kottsick was living there and told
officers that Backer resided at Backer's second shop. Kottsick voluntarily surrendered
a bag of methamphetamine and was interviewed by Officer Roger Becker. Kottsick
said he purchased a gram of methamphetamine from Backer at Backer's second shop
six days earlier. He stated that Backer kept methamphetamine on his person or in a
workbench at the shop. Kottsick also indicated that he saw firearms in Backer's
bedroom and on one occasion he saw a Street Sweeper 12-gauge shotgun on Backer's
bed.

       Officers searched Backer's second shop pursuant to a second search warrant
and found the Street Sweeper, a fully automatic machine gun, and approximately 54
other firearms in Backer's bedroom. Officers also seized drug paraphernalia and a
small amount of methamphetamine. Backer was indicted for (1) being an unlawful
user of a controlled substance and knowingly possessing 54 firearms; (2) knowingly
possessing a machine gun; (3) knowingly possessing a Street Sweeper shotgun which
had not been registered in the National Firearms Registration and Transfer Record;
and (4) knowingly possessing a firearm with an obliterated serial number. Backer
pled not guilty to all counts, however, following a jury trial, Backer was found guilty
on all counts.

       The district court sentenced Backer to a term of 60 months' imprisonment, two
years' supervised release, and a $15,000 fine. Backer and the government appealed.
We affirmed Backer's conviction, but reversed the sentence and remanded for
resentencing. United States v. Backer, 

, 509 (8th Cir. 2004). We held
that the district court erred in declining to assign a two-level enhancement under
U.S.S.G. § 2K2.1—one for destructive device and one for an obliterated serial
number. 

added six additional levels resulting in an offense
level of 29 and a sentencing range of 87 to 108 months. At resentencing, Backer did
not object to the Presentence Investigation Report and was resentenced to 87 months.
The Supreme Court announced its decision in Blakely v. Washington, 

                                         -2-
(2004), on the same day Backer was resentenced. Backer now appeals arguing that
changes to the federal sentencing guidelines affected by the Supreme Court's Blakely
and Booker decisions require a second remand for resentencing. We agree and
remand.

                                     II. Discussion
       We review the district court's sentence for plain error because Backer failed to
raise a Booker-type objection at sentencing but instead raised it for the first time on
appeal. United States v. Pirani, 

, 549 (8th Cir. 2005) (en banc) (a Booker
error "is preserved if the defendant below argued Apprendi or Blakely error or that the
Guidelines were unconstitutional").

       Backer first argues that the Guidelines enhancements violated his Sixth
Amendment rights as established under Apprendi v. New Jersey, 

(2000)
and United States v. Booker, 

(2005). These cases stand for the
proposition that "[a]ny fact (other than a prior conviction) which is necessary to
support a sentence exceeding the maximum authorized by the facts established by a
plea of guilty or a jury verdict must be admitted by the defendant or proved to a jury
beyond a reasonable doubt." 

. Booker clarified whether this
principle, which was first clearly enunciated in Apprendi, applied to the then
mandatory Federal Sentencing Guidelines. 

The Court's remedy for this
constitutional infirmity in the Guidelines was to excise the provisions of the
Guidelines that made them mandatory. 

      Backer argues that the Apprendi principle invalidates three sentence
enhancements he received: (1) six levels for possessing more than three firearms
under U.S.S.G. § 2K2.1(a)(4); (2) two levels for possessing a destructive device
under § 2K2.1(b)(3); and (3) two levels for an obliterated serial number under §
2K2.1(b)(4). We disagree. During Backer's sentencing, he admitted possession of the
weapons in question and our prior opinion resolved the legal question of whether one

                                         -3-
of those weapons was a destructive device. Additionally, the jury found the facts that
form the basis for these enhancements beyond a reasonable doubt. We affirm the
district court's sentencing enhancements.

        Backer also argues that upon remand, the district court imposed a sentence
under a mandatory guideline sentencing scheme in violation of Booker. Backer is
correct. However, because he made no Sixth Amendment argument below, we review
for plain error, 

, and analyze under the four-part test of United
States v. Olano, 

, 732 (1993). Under this test, there must be (1) error, (2)
that is plain, (3) that affects substantial rights, and (4) seriously affects the fairness,
integrity, or public reputation of judicial proceedings. The third prong of the Olano
test turns on whether Backer "has demonstrated a reasonable probability that he
would have received a more favorable sentence with the Booker error eliminated by
making the Guidelines advisory." 

.

        The first two requirements of Olano are satisfied because the district erred in
sentencing Backer under mandatory Guidelines and we have previously determined
that error to be plain. 

Our review of the record also shows that the court's
error affected Backer's substantial rights. Backer specifically sought a downward
departure based upon lack of criminal history and his possession of the weapons as
a collector. At the hearing, Backer also specifically requested a three-level reduction
for acceptance of responsibility. The district court made clear in its resentencing that
its sentence was a consequence of the mandatory nature of the Guidelines and the
prior opinion of this court. Also, the district court's prior sentence, which was 27
months shorter in duration, demonstrates a reasonable probability that upon
resentencing under Booker, Backer could receive a more favorable sentence. Lastly,
to affirm Backer's 87 month sentence under the present record would seriously affect
the fairness, integrity, or public reputation of judicial proceedings. We find that
Backer has met the Olano requirements and has proven plain error. For the foregoing



                                           -4-
reasons, we remand to the district court for resentencing, consistent with the
sentencing scheme detailed in Booker.
