Agustín Sergio DeLeon Garza appeals the within-guidelines life sentence imposed following his conviction of seven counts related to kidnaping, ransom, and money *263 laundering. He contends that his sentence is substantively unreasonable because it is greater than needed to achieve the sentencing goals of 18 U.S.C. § 3553(a).

Because DeLeon Garza did not raise a substantive reasonableness objection in the district court, his arguments, as he concedes, are reviewed for plain error only, based on this court’s precedent. See United States v. Mondragon-Santiago, 564 F.3d 357, 361 (5th Cir. 2009); United States v. Peltier, 505 F.3d 389, 391 (5th Cir. 2007). Nevertheless, DeLeon Garza argues that plain error review should not apply to preserve the issue for further review. To establish plain error, he must show that the district court committed a clear or obvious error that affected his substantial rights. See Puckett v. United States, 556 U.S. 129, 135, 129 S.Ct. 1423, 173 L.Ed.2d 266 (2009). Even if he does so, we will correct the error only if it seriously affects the fairness, integrity, or public reputation of the proceedings. Id.

DeLeon Garza has not shown error, plain or otherwise, in connection with his sentence. We presume that a within-guidelines sentence, such as DeLeon Garza’s, is reasonable. See United States v. Jenkins, 712 F.3d 209, 214 (5th Cir. 2013). A defendant can rebut the presumption only if he shows that the district court ignored an important sentencing factor, afforded substantial weight to an irrelevant or inappropriate factor, or clearly erred in weighing the factors. Id. DeLeon Garza’s arguments do not make this showing. Rather, he has shown only a disagreement with the propriety of the sentence imposed, which does not suffice to show substantive unreasonableness. See United States v. Ruiz, 621 F.3d 390, 398 (5th Cir. 2010). The judgment of the district court is AFFIRMED.
