I was ordering MLok accessories from Midwest Industries and I came across muzzle devices. I admit I took a chance and the price was hard to resist. At first glance the muzzle brake/compensater looks really large, bigger than the one on my SCAR 308. It’s 2-1/2 inches long and WIDE. But after one session at the range I’m a believer. Really works and the accuracy is phenomenal. A muzzle brake is not supposed to affect accuracy but I’m still getting .5 MOA at 100 yds so I’m not messing with a good thing and I’m leaving this on.
