Worth every penny
by Matt -
I wanted to swap the birdcage that came with my complete Aero upper (which I also purchased from Primary Arms), and my local armorer wasn't available so he advised me to just do it myself and to scoop up a set of these for easier indexing. PA had the best price (they usually do), and shipped them out to me super fast. I also ordered the actual muzzle brake from them for the swap as well (VG6 Epsilon; also at a steal price and also shipped super fast), and these washers made the process stupid easy. 10 minutes start to finish and I have a badass muzzle brake on my AR.
Great Alternative for Shims
by Andy -
Pretty slick for timing muzzle devices. I've used the PWS and Surefire shims for mounting devices on suppressor hosts and never liked the idea of stacking shims. With these you'll need one washer and drastically reduce opportunities for tolerance stacking. Narrowed it down to handful then chose the correct one when applying the final torque. Will use again.
