Also known as: LA-SF15 6mm ARC, Lantac SF15 6ARC, LA-SF15 6MM ARC
Overview
The LANTAC LA-SF15 6mm ARC is a precision-oriented semi-automatic rifle introduced by Lantac USA in 2020 to showcase Hornady's then-new 6mm Advanced Rifle Cartridge in the AR-15 form factor. The flagship 18-inch configuration pairs a Proof Research carbon-fiber-wrapped barrel with a 1:7.5 twist and target crown to a 'Rifle+1' length gas system, an enhanced forged receiver set, and a dedicated 6mm ARC E-BCG enhanced bolt carrier. A 15-inch Spada-ML free-float handguard, Geissele G2S two-stage trigger, VLTOR A5 buffer system, Magpul PRS precision stock and MOE grip, and Magpul MBUS Pro back-up sights make it a long-range-capable lightweight DMR that pushes a 108-grain projectile past 800 meters from a standard AR-15 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.
