Hi I got the cz858 large muzzle brake from wolverine supply. when i screw it on all the way the slot on the brake that the pin in the front site base goes in don't line up. the brake is about 1/4 off from turning on all the way. Does the brake have to screw on all the way or can i back it off a turn so the the pin lines up with the slot on the brake ??
