Before: GRIFFIN, BUSH, and NALBANDIAN, Circuit Judges.

NALBANDIAN, Circuit Judge. Zachary Bush pled guilty to illegally possessing

firearms and ammunition as a convicted felon. The district court sentenced him to 84 months’

imprisonment. Bush challenges his within-Guidelines sentence as procedurally and substantively

unreasonable. But we reject his arguments and affirm.

I.

A few days after Christmas in 2023, Bush was driving his car in Grand Rapids, Michigan,

and pulled aside another car waiting at an intersection. Bush and his passenger started yelling at

the other car’s driver, whom they had apparently encountered earlier that evening at a bar. When

the driver asked them what their problem was, Bush pointed a laser-equipped handgun at the driver

for about ten seconds and stated that he “does not talk but likes to play tag.” Revised Presentence

Report, pg. 6. The driver, who noticed a green dot on his chest, sped away. And Bush pursued

him briefly.
No. 25-1592, United States v. Bush

The driver eluded Bush and reported the encounter to the Grand Rapids police, which

investigated the encounter as a felonious assault involving a firearm. Soon after, the police located

Bush. They arrested him and searched him and his car. They found a loaded handgun, a loaded

shotgun, and nearly 200 rounds of ammunition.

Bush had two prior felony convictions: assault with a dangerous weapon and possession

of a controlled substance. So the federal government charged him with possessing guns and

ammunition as a felon. See 18 U.S.C. § 922 (g)(1). Bush initially posted bond. But the district

court remanded him to pretrial confinement after he tested positive for marijuana and

methamphetamine and after pretrial services officers discovered six large-bladed weapons, a pistol

grip, and drug paraphernalia where he lived.

Bush also had a history of mental health issues, so the court ordered a competency

evaluation. The evaluation found that Bush didn’t meet the criteria for post-traumatic stress

disorder or attention-deficit/hyperactivity disorder, but it characterized him as suffering from

“other specified trauma- and stressor-related disorder” and “other specified attention-

deficit/hyperactivity disorder.” And it opined that Bush could understand the charges and

proceedings against him. Based on the evaluation, the court found Bush mentally competent to

stand trial. Bush then pled guilty.

The government’s presentence report calculated Bush’s Sentencing Guidelines range. That

calculation included two enhancements: a two-level increase because the handgun in Bush’s

possession had been stolen, see U.S.S.G. § 2K2.1(b)(4)(A), and a four-level increase because Bush

used the handgun in connection with another felony—the aggravated assault of the other car’s

driver, see id. § 2K2.1(b)(7)(B). Bush received a three-level reduction based on his acceptance of

2
No. 25-1592, United States v. Bush

responsibility, see id. § 3E1.1, so his Guidelines range was 84 to 105 months. The government

recommended a sentence of 84 months.

In Bush’s sentencing memorandum, he accepted the presentence report’s facts and

Guidelines calculation as correct and didn’t advance any legal objections. But he requested a

downward departure or variance, asking the district court to impose a sentence below the

recommended range based on the 18 U.S.C. § 3553 (a) factors and his diminished mental capacity.

At the sentencing hearing, Bush’s counsel reiterated that he didn’t have any objections to

the presentence report. The district court adopted the report’s Guidelines range. And it then denied

Bush’s request for a downward departure, evaluated the § 3553(a) factors, denied Bush’s request

for a variance, and sentenced him to 84 months’ imprisonment.

Then, after the court imposed the sentence and began explaining Bush’s right to appeal,

Bush raised his hand, and the court allowed him to speak. Bush said that he had illegally possessed

the guns because he feared for his safety and described an incident where he was attacked by over

a dozen men in 2022. Pushing back against the government’s portrayal of him as the aggressor in

that incident, Bush remarked, “I never had a gun.” R.91, Sentencing Hr’g Tr., PageID 296. After

a few final comments, the court adjourned the hearing.

Bush appealed.

II.

Bush challenges his sentence on several grounds. He says that the district court erred in

applying the four-level in-connection-with-another-felony enhancement and the two-level stolen-

firearm enhancement. See U.S.S.G. §§ 2K2.1(b)(4), 2K2.1(b)(7)(B). And aside from the

enhancements, Bush argues that the court imposed a procedurally and substantively unreasonable

sentence by failing to: rule on Bush’s request for a downward departure, adequately explain why

3
No. 25-1592, United States v. Bush

Bush’s mental health wasn’t a mitigating factor, and afford enough weight to certain mitigating

factors.

A.

We’ll start with the enhancements. Bush argues that the district court procedurally erred

by applying the in-connection-with-another-felony and stolen-firearm enhancements. See United

States v. Potts, 947 F.3d 357, 364 (6th Cir. 2020) (“When evaluating a sentence for procedural

reasonableness, we . . . ask whether the district court properly calculated the Guidelines range.”).

And he says that he preserved his challenge to the enhancements because he denied having a gun

at the end of the sentencing hearing.

In response, the government argues that Bush’s challenges to the enhancements are

unreviewable because he either waived them or invited the errors. The government also says that,

even if we could review the challenges, Bush forfeited them, and they fail under plain-error review.

Identifying whether waiver, invited error, or forfeiture applies to a claim can make a

difference because we don’t review waived claims, and we review invited errors only when

necessary to prevent manifest injustice. See United States v. Cabbage, 91 F.4th 1228, 1231 (6th

Cir. 2024). But here, Bush’s challenges to the enhancements don’t hinge on whether his actions

precluded our review. At a minimum, Bush forfeited his challenges to the enhancements by not

objecting to them. See United States v. Montgomery, 998 F.3d 693, 698 (6th Cir. 2021). In which

case, plain-error review applies. Id. And under that standard, Bush’s challenges to the

enhancements fail.

To prevail under plain-error review, Bush must show that applying each enhancement was

an “(1) error (2) that was obvious or clear, (3) that affected [his] substantial rights and (4) that

4
No. 25-1592, United States v. Bush

affected the fairness, integrity, or public reputation of the judicial proceedings.” United States v.

Vonner, 516 F.3d 382, 386 (6th Cir. 2008) (en banc) (citation modified).

Resisting plain-error review, Bush argues that he preserved his challenges to the

enhancements. He points to the moment in the sentencing hearing when he said, “I never had a

gun,” in reference to the 2022 incident. R.91, Sentencing Hr’g Tr., PageID 296. And he

characterizes this remark as an objection to the enhancements. But even if this cursory remark

could be construed as an objection to the enhancements, Bush’s “I never had a gun” statement was

about the 2022 incident—not the 2023 assault that led to his arrest and provided the basis for the

enhancements. So there’s no merit to the contention that Bush’s remark preserved a challenge to

the enhancements. And regardless, Bush can’t prevail because both of his challenges fail on the

first step: Neither the application of the in-connection-with-a-felony enhancement nor the stolen-

firearm enhancement was an error.

For both enhancements, Bush argues that the district court erred in applying them because

the indictment didn’t allege the facts that the court must find to apply the enhancements. But Bush

is wrong. For enhancements in a federal prosecution, the government must charge only the facts

that would increase the mandatory minimum penalty or increase the defendant’s penalty beyond

the mandated maximum. See United States v. Cotton, 535 U.S. 625, 627 (2002); United States v.

Powell, 847 F.3d 760, 782 (6th Cir. 2017); United States v. Ely, 750 F. App’x 411, 413–14 (6th

Cir. 2018) (noting that “judicial factfinding that increases the penalty for a crime is

unconstitutional” but “judicial factfinding that affects the Guidelines range” is not). A felon-in-

possession violation doesn’t carry a mandatory minimum sentence but carries a maximum of 15

years’ imprisonment. See 18 U.S.C. § 924 (a)(8). Neither enhancement established a mandatory

minimum or maximum penalty above what was statutorily prescribed for a felon-in-possession

5
No. 25-1592, United States v. Bush

violation. So the government didn’t need to include in its indictment the facts required to apply

the enhancements.

Bush’s remaining challenges to the in-connection-with-another-felony enhancement also

fail. He contends that the district court made a factual error because there was insufficient evidence

to show that he pointed a gun at the other driver. Yet the presentence report described how Bush

did exactly that. And not only did Bush fail to produce evidence contradicting the facts set forth

in the presentence report, but he accepted the report’s facts as true in his sentencing memorandum

and at the sentencing hearing. The district court, therefore, was “entitled to rely on those facts

when sentencing” Bush. United States v. Geerken, 506 F.3d 461, 467 (6th Cir. 2007).

Relying on United States v. Kilgore, 749 F.3d 463 (6th Cir. 2014), Bush also argues that

the district court couldn’t apply the enhancement because the felonious assault wasn’t separate

from the felon-in-possession offense. To apply the enhancement, there must be “a separation of

time between the offense of conviction and the other felony offense, and a distinction of conduct

between that occurring in the offense of conviction and the other felony offense.” United States v.

King, 341 F.3d 503, 506 (6th Cir. 2003) (citation modified). Just like in King, where we upheld

the application of the enhancement because the defendant “first possessed the gun (offense of

conviction) and then used the gun (enhancement conduct)” to assault someone, Bush’s possession

of the gun and use of it to assault someone were temporally separate and behaviorally distinct. Id.

So the district court didn’t err.

Kilgore doesn’t help Bush. There, the defendant had illegally obtained guns as a convicted

felon by stealing them. Kilgore, 749 F.3d at 463. At sentencing, the district court applied both an

enhancement for the theft of the guns and the in-connection-with-another-felony enhancement,

with the theft as the other felony. Id. at 463–64. We held that the district court erred by applying

6
No. 25-1592, United States v. Bush

the in-connection-with-another-felony enhancement because the theft wasn’t separate and distinct

from possessing the guns, which was the offense of conviction. Id. at 464–65. But there, the

defendant would’ve “inevitably possessed firearms upon completion of the [theft] because the

firearms were among the items taken.” King, 341 F.3d at 507. In contrast, once Bush possessed

the guns illegally, he “could have refrained from using the weapon to commit assault.” Id. So

Kilgore is an inapt comparison. Instead, King controls.

Finally, Bush argues that the stolen-firearm enhancement, U.S.S.G. § 2K2.1(b)(4)(A),

applies only if he knew or reasonably should’ve known that the gun was stolen. But the stolen-

firearm enhancement doesn’t contain a knowledge requirement. United States v. Palos, 978 F.3d

373, 375 (6th Cir. 2020); United States v. Webb, 403 F.3d 373, 384 (6th Cir. 2005). And the lack

of a knowledge requirement in a sentencing enhancement doesn’t violate due process. See United

States v. Seuell, 135 F.4th 480, 485 (6th Cir. 2025). The district court, therefore, could properly

apply the stolen-firearm enhancement “even absent evidence that the defendant knew the [firearm]

was stolen” or should’ve known that it was. Webb, 403 F.3d at 384; see also U.S.S.G. § 2K2.1

cmt. n.8(B).

B.

Turning to Bush’s remaining arguments, he argues that the sentence was procedurally

unreasonable because the district court didn’t rule on his request for a downward departure and

inadequately explained why his mental health wasn’t a mitigating factor. He also raises a

substantive-unreasonableness challenge by arguing that the court didn’t properly weigh mitigating

7
No. 25-1592, United States v. Bush

factors, like his mental health and his pretrial conduct. But Bush’s claims don’t withstand a review

of the record.

“We generally review a claim of procedural or substantive unreasonableness under the

deferential abuse of discretion standard.” United States v. Hymes, 19 F.4th 928, 932–33 (6th Cir.

2021). And though the parties dispute whether plain-error review should apply to some of these

remaining claims, we needn’t resolve that dispute because we can affirm even without the added

deference of plain-error review.

For a procedural-reasonableness challenge, we ask whether the district court committed a

“significant procedural error, such as . . . failing to adequately explain the chosen sentence.”

Gall v. United States, 552 U.S. 38, 51 (2007). And, when the defendant appeals, a substantive-

reasonableness challenge is a claim that the sentence is too long. United States v. Rayyan, 885

F.3d 436, 442 (6th Cir. 2018). A sentence can be unreasonably lengthy “when the district court

selects the sentence arbitrarily, bases the sentence on impermissible factors, fails to consider

pertinent § 3553(a) factors or gives an unreasonable amount of weight to any pertinent factor.”

United States v. Sexton, 512 F.3d 326, 332 (6th Cir. 2008) (citation modified).

Bush first argues that his sentence was procedurally unreasonable because the district court

didn’t rule on his request for a downward departure. At the sentencing hearing, the court stated

that it had evaluated Bush’s arguments in his sentencing memorandum. After Bush’s counsel

chose to rest on his brief, the court explained its reasoning. It acknowledged that U.S.S.G.

§ 5K2.13—which has since been removed from the Guidelines, see U.S. Sentencing Guidelines

Manual App. B at 133, 204 (U.S. Sent’g Comm’n 2025)—authorized a downward departure if the

defendant committed the offense while suffering from a significantly reduced mental capacity that

contributed substantially to the commission of the offense. But § 5K2.13 didn’t authorize

8
No. 25-1592, United States v. Bush

departure if the reduced mental capacity was caused by the voluntary use of drugs or other

intoxicants, the defendant’s offense involved a serious threat of violence, or the defendant’s

criminal history indicated a need to incarcerate the defendant to protect the public. U.S.S.G.

§ 5K2.13 (repealed Nov. 1, 2025). The court found that these exceptions applied to Bush’s case,

so it rejected the downward departure and concluded by stating, “I will not depart.” R.91,

Sentencing Hr’g Tr., PageID 278. So we reject Bush’s characterization of the record; the district

court ruled on Bush’s request for a downward departure after explaining its reasoning.

Next, Bush argues that his sentence was procedurally unreasonable because the district

court inadequately explained why it didn’t view Bush’s mental health as a mitigating factor. When

reviewing the adequacy of the district court’s explanation, “[w]e simply ask whether the district

court showed its work such that we can meaningfully review how and why it crafted a sentence.”

Potts, 947 F.3d at 371.

A defendant’s mental health isn’t always a mitigating factor, particularly when the

defendant’s mental health issues present a danger to the public. See, e.g., United States v. Owen,

940 F.3d 308, 317–18 (6th Cir. 2019); United States v. Tolbert, 459 F. App’x 541, 547–48 (6th

Cir. 2012); United States v. Mills, 364 F. App’x 217, 220–21 (6th Cir. 2010). Here, the court

adequately explained why Bush’s mental health wasn’t a mitigating factor. The court recognized

that mental health is sometimes a mitigating factor but explained why it wasn’t in Bush’s case. It

noted that Bush’s mental health issues led him to “antagonize strangers with little to no

provocation.” R.91, Sentencing Hr’g Tr., PageID 288–89. And that behavior, along with Bush’s

past unwillingness to participate in mental health treatment, presented “a danger to the public.”

Id., PageID 290.

9
No. 25-1592, United States v. Bush

Turning to Bush’s substantive-reasonableness challenge, the district court didn’t abuse its

discretion in weighing the § 3553(a) factors. We give district courts the “benefit of the doubt when

we review their sentences and the reasons given for them.” Vonner, 516 F.3d at 392. And we

presume that within-Guidelines sentences are reasonable, which adds an extra layer of difficulty

for the defendant. United States v. Simmons, 587 F.3d 348, 365 (6th Cir. 2009); United States v.

Madden, 515 F.3d 601, 613 (6th Cir. 2008) (“This presumption exists precisely because a sentence

that both the Sentencing Commission and the sentencing judge agree on significantly increases the

likelihood that the sentence is a reasonable one.” (citation modified)).

The district court viewed the violent nature of Bush’s offense and his past violent crimes

as aggravating factors but didn’t view Bush’s drug use as much of a concern. And it regarded

Bush’s possession of weapons while on bond and his history of non-compliance with court orders

as aggravating. As stated already, the court believed Bush’s mental health issues presented a

danger to the public. So it denied Bush’s request for a variance, viewing “the seriousness of the

offense and protection of the public” as the most important considerations guiding its decision.

R.91, Sentencing Hr’g Tr., PageID 290–91. The district court’s emphasis on protecting the public

wasn’t an abuse of discretion. See Sexton, 512 F.3d at 332 (“Considering the deleterious effect

that [cocaine trafficking] would naturally have on a community, it was not unreasonable for the

district court to give less weight to [the defendant’s] personal characteristics.”). And though Bush

says that the court ignored his pretrial conduct, Bush’s active participation in mental health

treatment during pretrial confinement is what motivated the court to select the low end of the

Guidelines range, an 84-month sentence.

Finally, Bush says that the district court should’ve afforded more weight to his mental

health issues and pretrial conduct. But that argument “ultimately boils down to an assertion that

10
No. 25-1592, United States v. Bush

the district court should have balanced the § 3553(a) factors differently.” Id. Such an argument

“is simply beyond the scope of our appellate review, which looks to whether the sentence is

reasonable, as opposed to whether . . . we would have imposed the same sentence.” Id. (citation

modified). So Bush falls short of overcoming the presumption of reasonableness we apply to the

district court’s within-Guidelines sentence.

III.

For these reasons, we affirm the district court’s judgment.
