The LWRC Six8-A5 in 6.8 SPC II (brand part no. SIX8A5RB16) is a piston-operated, semi-automatic AR-platform rifle built around proprietary upper and lower receivers optimized specifically for the 6.8 SPC II cartridge. LWRC cuts the 16-inch barrel as a cold hammer-forged, spiral-fluted design at a 1:10 twist, threaded 5/8×24 for muzzle devices and finished with an A2 birdcage flash hider. The fully ambidextrous lower carries an ambidextrous charging handle and sling mount, LWRCI’s enhanced fire control group, Skirmish back-up iron sights, an adjustable 2-position gas block, a 12-inch user-configurable rail system, a Magpul MOE+ grip, and an adjustable compact stock, finished in black. Note that the Six8-A5 uses LWRC’s unique Magpul 30-round 6.8 SPC magazines; standard AR-15 magazines are not interchangeable with this platform. Among AR-platform rifles in the AR rifles category, the Six8-A5 favors shooters who want a purpose-built piston rifle in the 6.8 SPC II cartridge.
