Williams Ruben Ramos-Castillo (Ramos) appeals the sentence he received fol*645lowing his guilty plea conviction for illegal reentry, in violation of 8 U.S.C. § 1326. Ramos argues that his within-guidelines 50-month sentence is substantively unreasonable because it was greater than necessary to satisfy the sentencing goals outlined in 18 U.S.C. § 3553(a). He asserts that the district court should have sentenced him below the guidelines range of imprisonment because the unlawful reentry Guideline is not empirically based and effectively double counts a prior conviction and because his individual characteristics warranted a lower sentence.
The substantive reasonableness of a sentence is reviewed for an abuse of discretion. Gall v. United States, 552 U.S. 38, 51, 128 S.Ct. 586, 169 L.Ed.2d 445 (2007). Although Ramos argued for a downward variance, he failed to object after the imposition of his sentence, such that review is arguably for plain error. See United States v. Peltier, 505 F.3d 389, 391-92 (5th Cir.2007); but see United States v. Flanagan, 87 F.3d 121, 124 (5th Cir.1996). This court need not determine whether plain error review is appropriate because Ramos’s arguments fail even under the abuse-of-diseretion standard of review. See United States v. Rodriguez, 523 F.3d 519, 525 (5th Cir.2008).
Ramos’s arguments regarding the reentry Guideline are foreclosed by this court’s precedent. See United States v. Duarte, 569 F.3d 528, 530-31 (5th Cir.2009). Further, he has not rebutted the presumption of reasonableness that applies to his within-guidelines sentence. See United States v. Campos-Maldonado, 531 F.3d 337, 338 (5th Cir.2008); United States v. Gomez-Herrera, 523 F.3d 554, 565-66 (5th Cir. 2008).
AFFIRMED.
