Rockset & strap wrench - Guntec USA AR 9mm Slip Over Barrel Shroud w/Multi Port Muzzle Brake

I brought this for cosmetic purposes only for my AR9 I just wanted a taticool “tucked” look for my 8in barrel and this did the trick. Shot it off in the first 20 rounds. I used red loctite and a strap wrench to get good torque on the muzzle device the second time around. 300 rounds later no problems and the gun shoots a little softer. A $20 strap wrench is a must to install this.
