The Tex-Rex® .457 Big Bore PCP Carbine Air Rifle delivers serious stopping power in a compact, field-ready design. Precision CNC-machined in Fort Worth, Texas, this hard-hitting air rifle is made for hunters who demand performance, reliability, and maneuverability. With energy levels reaching up to 900+ foot-pounds of energy, the Tex-Rex Carbine brings devastating impact in a lighter, more agile platform.
Outfitted with a 24.75” Lothar Walther precision barrel and a user-adjustable Bias Port orifice system, the .457 Carbine allows shooters to tune velocity and air efficiency for different hunting needs. Weighing approximately 6.95 lbs unscoped, it’s ideal for spot-and-stalk hunts, still hunting, or close-quarter blinds.
The new Tex-Rex forearm has been upgraded with a rugged, extended design featuring nine precision-cut M-LOK® slots—giving hunters and shooters enhanced flexibility for mounting bipods, slings, lights, and other essential accessories. Securely fastened to the rifle’s frame, this forearm not only improves accessory compatibility but also adds extra grip and control in the field. Whether on a blind, rest, or stalking through brush, it’s built for real-world performance.
The Tex-Rex Carbine is now also equipped with an upgraded 500cc carbon-fiber bottle, a full-length Picatinny scope rail, upper and lower 11mm dovetail accessory rails, and a newly added manual safety for improved control in the field.
