Juan Arriaga, Jr., appeals his guilty-plea conviction for unlawful possession of a ma-chinegun. He argues that the factual basis was insufficient to support his plea because the factual resume did not include or mention a Zavasta machinegun as alleged in Count One of the indictment, which he contends was an essential element of the offense, and only referred to *288 his possession of a machinegun. Arriaga did not raise this issue in the district court. Accordingly, we review for plain error only. See United States v. Broussard, 669 F.3d 537, 546 (5th Cir. 2012).

Before accepting a guilty plea, the district court must determine that the conduct admitted by the defendant “is sufficient as a matter of law to constitute a violation of the statute.” United States v. Marek, 238 F.3d 310, 314 (5th Cir. 2001) (en banc) (emphasis omitted). If sufficiently specific, an indictment or information can be used as the sole source of the factual basis for a guilty plea. United States v. Garcia-Paulin, 627 F.3d 127, 133 (5th Cir. 2010). The record, read in pari materia with the indictment, may also establish the existence of a factual basis. United States v. Bachynsky, 949 F.2d 722, 730 (5th Cir. 1991).

. Here, the sole count of the indictment specifically charged Arriaga with the knowing possession of a machinegun, to wit, the Zavasta machinegun, identifying it by make, model, caliber, and serial number. The indictment was not a mere “recital of the statutory requirements.” Garciar-Paulin, 627 F.3d at 133. At rear-raignment, Arriaga stated that he had read the indictment, that he understood the charge against him, that he understood the essential characteristics of a ma-chinegun, and that he committed the offense as charged. Although the district court did not read aloud the indictment, the reading being waived by counsel, the court’s confirmation that Arriaga had read the indictment, understood the charge against him, and had committed the offense was sufficient to establish the factual basis for the charge. See id. The judgment of the district court is affirmed.

AFFIRMED.
