See Fed. R.App. P. 34(a); 10th Cir. R. 34.1(G). The cause is therefore ordered submitted without oral argument.
    
   ORDER AND JUDGMENT

PAUL KELLY, JR., Circuit Judge.

Petitioner Ramon Montano, a prisoner proceeding pro se, appeals from the district court’s dismissal of his petition for a writ of audita querela under the All Writs Act, 28 U.S.C. § 1651. The district court dismissed Mr. Montano’s motion for Rule 52(b) relief and petition for a writ of audita querela as subsumed by 28 U.S.C. § 2255. The district court did not, and was not required to, recharacterize the petition as arising under § 2255 because such a petition likely would have been time-barred. See United States v. Valadez-Camarena, 402 F.3d 1259, 1261 (10th Cir.2005).

Mr. Montano was convicted of various federal drug offenses and sentenced to 30 years’ incarceration in 1997. We affirmed his convictions on direct appeal. United States v. Montano, No. 97-2356, 1999 WL 110666 (10th Cir. Feb.26,1999). Mr. Mon-tano now argues that his sentence, issued under mandatory guidelines, is unconstitutional.

A writ of audita querela (“hear the complaint”) challenges a judgment that was correct when entered but later rendered infirm. See United States v. Torres, 282 F.3d 1241, 1245 n. 6 (10th Cir.2002). It is unavailable to Mr. Montano if he could have challenged his sentence under 28 U.S.C. § 2255. Id. at 1245. Mr. Montano claims “no statutory remedy is adequate or available,” Aplt. Br. 2, but he does not explain why § 2255 is insufficient. Merely because such relief may be time-barred does not render § 2255 inadequate or unavailable. See Caravalho v. Pugh, 177 F.3d 1177, 1178 (10th Cir.1999); Heijnen v. United States, 441 Fed.Appx. 603, 604, 2011 WL 5843642, at *2 (10th Cir.2011) (unpublished opinion) (affirming a similar dismissal on the merits).

AFFIRMED. 
      
       This order and judgment is not binding precedent, except under the doctrines of law of the case, res judicata, and collateral estoppel. It may be cited, however, for its persuasive value consistent with Fed. R.App. P. 32.1 and 10th Cir. R. 32.1.
     
      
      . Mr. Montano requested a certificate of ap-pealability (“COA”), 28 U.S.C. § 2253(c)(1)(B), which the government opposed. However, a COA is not required as this is not a § 2255 appeal. Valadez-Camarena, 402 F.3d at 1259 n. 1.
     
      
      . The writ of audita querela was abolished by Federal Rule of Civil Procedure 60(e), but we have joined other circuits in assuming, without deciding, that it remains available under the All Writs Act. Torres, 282 F.3d at 1245 n. 6.
