Also known as: LA-SF15 300BLK CQB, Lantac SF15 300 Blackout CQB, LA-SF15 300BLK CQB 11.5"
Overview
The LANTAC LA-SF15 300BLK CQB is the .300 Blackout member of Lantac USA's short-barrel LA-SF15 family, offered in both pistol and SBR forms on a shared 11.5-inch nitrided 416R stainless barrel. Chambered specifically for .300 AAC Blackout, it uses a pistol-length gas system tuned to cycle both supersonic and subsonic loads, making it a natural host for a suppressor. Like the rest of the LA-SF15 line it is built on the enhanced forged receiver set with the E-BCG enhanced bolt carrier, a Dragon PlanB short muzzle brake, a 10.5-inch Spada-ML free-float handguard, and B5 Systems furniture, yielding a compact, hard-hitting close-quarters platform.

Background
LANTAC built its reputation on the Dragon muzzle brake, a recoil-taming device that became a fixture on high-end ARs before the company offered complete rifles. The LA-SF15 is the firm's distillation of that aftermarket knowledge into a factory rifle: enhanced forged receivers, the patented CP-R360 Domed Head cam pin, and the E-BCG enhanced bolt carrier that vents gas forward and away from the shooter. Each rifle is shot-tested before it leaves the Texas facility and carries a lifetime warranty.
