Muzzle decice - Guntec USA AR-15 Mini Slip Over Barrel Shroud with Multi Port Muzzle Brake

I bought one for my Psa jakl. Looks awesome on the firearm. Only problem I have with it is my jakl is a 5.56 with a 10.5 inch barrel. I went from a linear comp to this and I have no clue why, but this thing is loud and very concussive. I went from shooting the jakl with the slip over muzzle device on to shooting a dpms kitty kat with nothing but a retro 3 prong flash hider. The jakl was wayyy louder and more concussive than the kitty kat. Which I’m usually apologizing to people at the range when I bring out the kitty kat because it’s so obnoxiously loud.
