Before LOKEN, Chief Judge, MELLOY and BENTON, Circuit Judges.
                              ___________

BENTON, Circuit Judge.

       A jury convicted Benjamin Thomas of possession of a firearm by a felon. 18
U.S.C. § 922(g)(1). At sentencing, the district court1 applied a four-level
enhancement under U.S.S.G. § 2K2.1(b)(6) for possessing the firearm in connection
with another felony – burglary. Thomas appeals his conviction, claiming
insufficiency of the evidence. He also appeals his sentence, arguing the district court
should not have applied the § 2K2.1(b)(6) enhancement. Jurisdiction being proper
under 28 U.S.C. § 1291 and 18 U.S.C. § 3742(a), this court affirms.

      1
        The Honorable Mark W. Bennett, United States District Judge for the Northern
District of Iowa.
                                          I.

       Thomas, along with two others, Cameron Williams and Michael Leslie, drove
to the apartment of an acquaintance with whom they had a dispute. Williams testified
that Thomas was upset on the way there. Thomas was the first to approach the
apartment, which shares a porch entrance with a separate apartment. Entering the
porch, Thomas opened the door to the wrong apartment. The occupant testified that
Thomas came into the apartment for about two seconds with a gun “in his right hand.”
Thomas held the gun “straight down at his side.” Williams said, “wrong door.”
Thomas closed the door and started knocking on the other apartment’s door.

       The occupant called the police. When theyarrived, Williams and Leslie were
walking away, while Thomas was knocking on the acquaintance’s front door. The
officers detained Williams and Leslie. When the officers approached Thomas, he
“act[ed] like he was sleeping” on the porch floor. An officer testified that Thomas
was wet with his own urine. Police located a revolver on the ground near the porch.
Minutes later, in a line-up, the occupant identified Thomas as the armed intruder.

       At trial, Williams testified that Thomas, an alcoholic at the time, was drunk on
the night of the incident. An officer stated that Thomas had the odor of alcohol on
him.

       The presentence investigation report determined that Thomas’s felon-in-
possession-of-a-firearm offense resulted in an advisory guidelines range of 100 to 125
months imprisonment. The PSR recommended a four-level enhancement for
possession in connection with a burglary. Thomas objected to the enhancement. The
court stated:

      And I’m overruling that objection. And I find that the trial evidence
      establishes that the defendant had the intent to commit a burglary and


                                         -2-
      admittedly went to the wrong apartment, but I don’t think that makes any
      difference, and I think he was angry and upset and had the necessary
      intent. So I think the four-level enhancement based on the trial
      testimony in this case is entirely consistent with my view of the
      evidence.

With the enhancement, the court determined an advisory range of 140 to 175 months.
The court imposed a 120-month sentence, the statutory maximum for the offense.

                                           II.

       Thomas argues the district court erred in denying his motion for judgment of
acquittal, claiming insufficiency of the evidence. A district court’s denial of a motion
for judgment of acquittal is reviewed de novo. See United States v. Harris, 

, 365 (8th Cir. 2003). This court views the evidence in the light most favorable
to the government, resolving evidentiary conflicts in favor of the government, and
accepting all reasonable inferences drawn from the evidence that support the jury’s
verdict. See United States v. Baker, 

, 338 (8th Cir. 1996). The court will
reverse a jury’s verdict only where “no reasonable jury could have found the [accused]
guilty beyond a reasonable doubt.” United States v. Harmon, 

, 892 (8th
Cir. 1999).

       Thomas claims the government did not establish that he possessed a firearm.
At trial, the apartment occupant testified that Thomas possessed a firearm when
entering the apartment. He also stated that he picked Thomas out of a line-up minutes
after the intrusion. Thomas attacks the witness’s credibility, but these attacks are
unavailing. See United States v. Funchess, 

, 701 (8th Cir. 2005) (“We
do not consider attacks on witnesses’ credibility when we are evaluating an appeal
based upon the sufficiency of the evidence.”); United States v. Brown, 

,
692 (8th Cir. 2005) (“[W]e have long held that the jury is always the ultimate arbiter
of a witness’s credibility, and thus we will not disturb the jury’s findings on appeal.”)

                                          -3-
(internal quotations omitted). This court concludes that the evidence supports the
jury’s conviction, and the district court properly denied Thomas’s motion for
judgment of acquittal.

                                          III.

       Thomas argues that the court committed sentencing error by applying a four-
level enhancement for burglary under U.S.S.G. § 2K2.1(b)(6).2 This court reviews the
district court’s legal conclusions de novo, and its factual findings for clear error.
United States v. Anderson, 

, 724 (8th Cir. 2003). “A finding is ‘clearly
erroneous’ when, after reviewing the entire evidence, the court is left with the firm
conviction that a mistake has been made.” United States v. Marks, 

,
1017 (8th Cir. 2003). “A district court’s finding regarding a defendant’s purpose in
possessing a firearm is a finding of fact.” United States v. Harper, 

, 649
(8th Cir. 2006).

       Thomas claims that the government failed to prove he committed a burglary.
“When the proposed enhancement is based upon an offense for which there was no
prior conviction . . . ‘the government must prove at sentencing (by a preponderance
of the evidence) that the defendant committed it.’” United States v. Phillips, 

, 688 (8th Cir. 2007), quoting United States v. Raglin, 

, 677 (8th Cir.
2007). Iowa Code § 713.1 defines burglary:

      Any person, having the intent to commit a felony, assault or theft therein,
      who, having no right, license or privilege to do so, enters an occupied
      structure, such occupied structure not being open to the public, or who
      remains therein after it is closed to the public or after the person’s right



      2
       “If the defendant used or possessed any firearm or ammunition in connection
with another felony offense[,] . . . increase by 4 levels.” U.S.S.G. § 2K2.1(b)(6).

                                          -4-
      license or privilege to be there has expired, or any person having such
      intent who breaks an occupied structure, commits burglary.

Thomas disputes that he “entered” the apartment. “Entry, in terms of the burglary
statute, occurs when any part of the body enters an occupied structure.” State v.
Keopasaeuth, No. 99-1960, 

, at *3 (Iowa Ct. App. Nov. 16, 2001)
(unpublished), citing State v. Nichols, 

, 164 (Iowa Ct. App. 1997).
In this case, the occupant testified that Thomas had opened the door and “come into
my apartment.” The district court did not clearly err in finding that Thomas entered
an occupied structure not open to the public.

       Thomas asserts that he did not possess “the intent to commit a felony, assault
or theft.” The government argues that Thomas intended to commit an assault. “In
order to sustain a conviction for burglary the State must prove . . . [the defendant] had
formed the intent to commit an assault at the time of entry.” State v. Lambert, 

, 813 (Iowa 2000). “[T]he element of intent in burglary is seldom
susceptible to proof by direct evidence,” and is usually established by inference. State
v. Olson, 

, 136 (Iowa 1985). “Intent may be derived from actions
preceding, or subsequent to, an accused’s unauthorized entry, as well as all
circumstances attendant thereto.” 

, citing State v. Finnel,

, 42 (Iowa 1994).

        Iowa Code § 708.1 defines the crime of assault as when a person, without
justification, “[i]ntentionally points any firearm toward another, or displays in a
threatening manner any dangerous weapon toward another.” Iowa Code § 708.1(3)
(emphasis added). In State v. Harris, two renters had a disagreement with the
defendant over the terms of a lease. No. 04-1238, 

, at *1 (Iowa Ct.
App. June 15, 2005) (unpublished). The next morning, the defendant locked the
renters out of the building and remained inside with a rifle. When the renters
approached, the defendant “appeared to be very angry,” and “held the rifle at ‘port


                                          -5-
arms’ or ‘ready’ position . . . with the right hand near the trigger and the left on the
barrel of the gun.” 

concluded that, “[a]lthough Harris did not point the
weapon at [the renters], . . . the gun was displayed in a threatening manner at the time
of the incident.” Id.; see also United States v. Anderson, 

, 725 (8th Cir.
2003) (concluding defendant “displayed his firearm in a threatening manner” based
upon testimony that he was walking “with a gun in his hand” and “waving the gun”).

        In this case, Thomas was “upset” and entered the wrong apartment with a gun
drawn and loaded. The occupant testified that he saw the barrel “out of the end of
[the] right sleeve of his coat.” While Thomas did not point the gun, it was in the ready
position with his hand near the trigger. This court concludes that he committed assault
by intentionally displaying a dangerous weapon in a threatening manner.

        Thomas also claims the defense of voluntary intoxication. Voluntary
intoxication is a defense to burglary if it prevents a person from forming the specific
intent to commit a crime. See State v. Caldwell, 

, 557 (Iowa 1986).
Thomas argues that the record demonstrates he did not form the requisite intent to
commit burglary – Williams testified that he was drunk, there was alcohol on his
breath, and the police found him lying down in his own urine. See United States v.
Raglin, 

, 677 (8th Cir. 2007) (“[W]hen [the defendant] presented
evidence arguably supporting a self-defense or a justification defense to the charge .
. . the government had to negate that defense by a preponderance of the evidence . .
. .”). The government established that Thomas armed himself, drove Williams and
Leslie to the apartment, was the first to approach it, and immediately withdrew from
the wrong apartment only to turn his attention to the correct door. Thomas also
attempted to hide his conduct once police arrived, tossing the revolver off the porch
and pretending to be asleep. The district court did not err in concluding that the




                                          -6-
government negated Thomas’s voluntary intoxication defense by a preponderance of
the evidence.

      The district court did not err in applying the § 2K2.1(b)(6) enhancement.

                                        IV.

      The judgment of the district court is affirmed.
