Was able to perfectly align my efab hybrid muzzle devoice with this. - Precision Armament Accu-Washer Muzzle Device Alignment System

Since I ordered the EFAB muzzle device, I had to pick this up as well in order to properly align the EFAB on my barrel (not sure if this is required for all Precision Armament muzzle devices). The muzzle alignment system comes with 18 washers of varying thickness, each marked with thin/thick notches on the sides (directions indicate the notches corresponding to how the washers are numbered, #1 being smallest while #18 being the thickest). The alignment process is not difficult but can take up to 30mins to figure out the correct washer. You simply start from the thickest washer (#18) and work your way down. Each washers go thinner by a 20° turn. You'll find the right washer when you've hand-tightened the muzzle device with 30° left until perfect alignment, thats when you use a muzzle wrench to tighten the rest of the way.
