The Inferna w/SBA5 Brace 12.5-inch LR-308 .308 Win Pistol Full Build Kit from Davidson Defense brings fire and fury to your bench with a build engineered for power, precision, and style. At its core is the 12.5-inch “Mandrake” barrel—crafted from 4150 Chrome Moly Vanadium and finished in nitride for maximum durability—featuring a medium profile and a 1:10 twist rate that’s tailor-made for .308 Win performance.
The Aero Precision 308 M5 upper lays the foundation for strength and fitment, while the 6061-T6 aluminum M-LOK handguard adds lightweight versatility with sleek black style. A nitride LR-308 bolt carrier group made from 9310 steel ensures smooth, reliable cycling, and the steel flash can muzzle device keeps the fire directed forward where it belongs. Anchoring the back end is the SB Tactical SBA5 brace, giving you comfort, stability, and tactical control in one rugged package. Built for those who forge their own path, the Inferna is the perfect companion for gunsmiths ready to unleash precision with every shot.
