The Inferna w/SBA4 Brace 12.5-inch LR-308 .308 Win Pistol Full Build Kit from Davidson Defense isn’t just built to perform—it’s built to dominate. At its core lies the 12.5-inch “Mandrake” barrel, forged from rugged 4150 Chrome Moly Vanadium and finished in nitride for superior endurance. With a 1:10 twist rate and carbine-length gas system, it’s tuned for reliable cycling and precise accuracy, shot after shot. The Recoil Technologies Micro Low-Profile Gas Block keeps your system running smooth, while the Aero Precision 308 M5 High Profile Upper Receiver anchors the build in premium performance.
Wrapped in a lightweight M-LOK handguard made of 6061-T6 aluminum, you’ve got the freedom to mount whatever the mission demands. The Steel Flash Can Design helps control your blast signature, and a nitride LR-308 Bolt Carrier Group brings the reliability to match. Topping it all off is the SB Tactical SBA4 Adjustable Pistol Stabilizing Brace—bringing comfort, control, and tactical adaptability to the table. For gunsmiths chasing that balance of firepower, finesse, and freedom, the Inferna is your flame-forged solution.
