The Tungsten Gray LWRC SIX8-A5 rifle in 6.8 SPC II (LWRC part no. SIX8A5RTG16) comes from LWRC as a piston-driven AR built around the 6.8 cartridge and its dedicated magazine. LWRC designed the upper and lower receivers, the enlarged ejection port and a Magpul-made magazine to work together, so the 6.8 feeds the way it should. The finish is Tungsten Gray, one of five colors LWRCI offers on the line, and the controls are fully ambidextrous. It carries a 16.1-inch barrel, a short-stroke gas piston and a 12-inch rail for accessories. It suits hunters and range shooters who want more energy than 5.56 from a carbine-size rifle.

Key Specifications

• Chambering is 6.8 SPC II, a cartridge LWRC chose to deliver more impact energy than 5.56 NATO from a carbine-size rifle.
