F-1 Firearms is an American manufacturer based in Spring, Texas, producing billet AR-15 and AR-10 rifles and components. Their receivers are skeletonized from 7075-T6 aluminum billet, reducing weight while retaining structural strength. The BDR-15 3G is an AR-15 configured for competitive shooting; the BDRX-10 is a lightweight AR-10 chambered in 6.5 Creedmoor and .308 Winchester for precision shooting and hunting. F-1's U-DRIVE upper receiver system is designed for compatibility across their platform. Standard features include match-grade barrels, ambidextrous controls, and modular handguards.
