A Texas man who tapped a Denver-area network to score .50-caliber "anti-materiel" sniper rifles is headed to federal prison, in a case that highlights how high-powered hardware can quietly move out of state through coordinated straw purchases.
Filiberto Walle, 24, of Edinburgh, Texas, pleaded guilty in December 2025 to conspiracy and to engaging in the business of dealing firearms without a license, according to a press release from the U.S. Attorney's Office for the District of Colorado. Prosecutors say the activity took place in mid 2023, with Walle arranging for third parties to buy the rifles so he could resell them. The plea papers describe how others completed the background checks and took physical possession of the guns before they were diverted out of Colorado.
Short prison terms and surrender order
On Friday, a federal judge in Denver sentenced Walle to nine months on each count, to be served at the same time. The court allowed him to walk out of the courtroom and ordered him to report to federal custody within two weeks, CBS Colorado reported. Coverage states that Walle was arrested in November 2024 and that his plea deal requires him to give up at least five of the rifles he had obtained. The relatively short concurrent terms stand in contrast to prosecutors' description of the weapons as powerful enough to disable vehicles and equipment.
How prosecutors say the operation worked
According to the federal plea agreement and indictment, Walle teamed up with a Denver resident who helped line up purchases and find people willing to complete the paperwork and physically leave stores with the guns before delivering them to Walle, the U.S. Attorney's Office says. Investigators identified multiple participants who filled out background-check forms and completed transfers for Walle, conduct prosecutors labeled as straw purchasing, and part of a broader conspiracy.
Models, dealers and the ATF probe
Reporting identifies the rifles as Barrett 82A1 and Desert Tech HTI .50-caliber models, described as commercially available anti-materiel weapons, and notes that the Bureau of Alcohol, Tobacco, Firearms, and Explosives led the criminal investigation, CBS Colorado reported. A spokesperson for the U.S. Attorney's Office told reporters that the Colorado gun dealers sold the firearms legally and had no sign that the buyers planned to divert them out of state.
Legal implications
Federal law bars anyone who is not a licensed importer, manufacturer, or dealer from engaging in the business of dealing firearms, and provisions in Title 18 of the U.S. Code criminalize unlicensed dealing, along with false statements in firearm transactions. Those sections allow prosecutors to seek fines and prison terms in trafficking cases. The relevant statutes appear in U.S. Code, Title 18, which provides the legal framework for the charges.
The Denver prosecution and the ATF investigation that led up to it highlight a federal push to stop commercial firearms from being diverted through straw buyers. Prosecutors and agents say the case shows how quickly high-caliber rifles can move from a retail counter in Colorado to another state when sellers are misled about who the real buyer is.
