Tex-Rex® Brush Gun Big Bore Air Rifle

$1,469.95

Compact. Devastating. American Made.

The Tex-Rex® Brush Gun Big Bore Air Rifle is the most compact and maneuverable rifle in the Tex-Rex lineup—engineered for hunters who operate in tight cover where speed, control, and raw stopping power matter most. Precision CNC-machined in Fort Worth, Texas, this ultra-short big bore is available in .510 and .457 calibers, delivering 700+ foot-pounds of energy (with a 620-grain slug in .510) from a rugged 16” barrel designed to dominate dense brush and confined hunting environments.

Built for fast handling and aggressive field use, the Tex-Rex Brush Gun brings uncompromising big-bore performance into an exceptionally compact footprint. The shortened barrel dramatically improves maneuverability in blinds, thick mesquite, and heavy woods—without sacrificing the devastating terminal energy Tex-Rex rifles are known for.

This latest evolution of the Tex-Rex platform features a full-length Picatinny scope rail for modern optics, upper and lower 11mm dovetail accessory rails for added flexibility, and a manual safety for enhanced control in the field.
