Does anybody have one of these? I have one, two warcomps, and a regular 3-prong. My question, has anyone noticed the 4-prong shims are different from the commercial muzzle devices? The colors are different, and the thickness of the shims are definitely different. I installed the 4-prong today, and it timed up perfectly relatively quickly compared to my other devices, didn’t even need the timing wheel. The shims with the 4-prong just seem to be more durable, and way better than the commercial shims. Of course, I could be hallucinating all of this quite easily, though. So, what say you all?
