Great product - VG6 Precision Lambda PRS65 Muzzle Brake

I installed this on a 6.5 20" grendel barrel. Install was pretty straight forward. I tried to install it incorrectly a few times to see if it would still install...difficult to accomplish which is good. You don't need a gunsmith to install this, just a little patience. After shooting about 25 rounds it was still tight. The recoil reduction is much better than expected. The Grendel now has less recoil than a 5.56 16" mid length w/ standard A2 flash-hider. I recommend this product to anyone who wants a smoother transition from shot to shot. It's money well spent if you enjoy shooting.
