Western Airguns is a U.S. premium big-bore PCP manufacturer producing semi-auto and full-auto large-caliber rifles including the Rattler, Sidewinder, Bushbuck, and Mordax platforms with USA-made barrels.

In our words

Western Airguns is one of the few credible domestic big-bore brands, and one of an even smaller number that does semi-auto and full-auto in big-bore calibers. The Rattler 357 and Rattler 45 Long Strike are the centerpiece platforms; Sidewinder fills the lighter big-bore slot; Mordax Venom takes the platform into pistol-format full-auto. U.S. support through Airguns of Arizona, Edgun West, and Fox Air Power is solid. Listings should always include chrono data, projectile, magazine count, and bottle hydro status because big-bore buyers care.

Real-world commentary

Western Airguns built a reputation quickly as one of the very few credible domestic big-bore makers, with USA-made barrels, premium components, and a niche in semi-auto and full-auto large-caliber rifles that few competitors match. The Rattler series and Mordax pistols are the standout platforms in the catalog.
