    Best Muzzle Device on the Market Hands down!!!!

    Published by James on 5th Sep 2018

    Keeps the muzzle completely neutral during fire, lessens the perceived recoil, isn't overly concussive, offers sacrificial baffles, rock solid suppressor host, looks awesome, super durable finish, made locally by a veteran owned company, and does a pretty good job with flash reduction. Keep up the great work Griffin!!!
