We've seen a great deal of experimentation with ARs built to feed cartridges other than the standard .223 Rem./5.56 NATO, and the 6.8 SPC has emerged as one of the more popular choices for gun owners.
LWRC has offered the Six8 platform — engineered specifically for the 6.8 SPC — for a few years now, and the company's latest development in that line is the Six8 Razorback.
The new Razorback uses LWRC's short-stroke gas piston system, sports an ambidextrous safety and charging handle and features a 12-inch free-floating handguard up front and LWRC's adjustable stock at the rear. The rifle has flip-up iron sights and feeds from magazines specially built for the 6.8 SPC round.
