The 6.8 uses all sorts of different thread pitches from maker to maker, ranging from 1/2x36 for Model 1 Sales, to 9/16x24, to 5/8x24.
thats because they need to standardize the 308 cal AR platform first LOL. theres what AR 10, and then the SR 25 which parts are not interchangeable. Someone needs to cave and create a benchmark standard for the platform.
