Better day than I had wash!!!!
my mount says it'll be here Saturday, ups must be handing it off to usps on Friday cuz they can't complete the job, I'm on call this weekend might try and hit the range next weekend
If it was complete head spacing was most likely checked by manufacturer I wouldn't suspect muzzle device in that case either maybe? Shoot it more see what happens then like SS said if your not happy contact the manufacture
Welcome to the forum

Another thing I like the MWI ones better than the magpul ones. MWI uses a gloss finish, they're smooth in operation. The magpul ones are a flat finish and they're kinda gritty.
Only thing that worries me is the hight of the rail on the arak it sits higher than a normal ar but like I said I'm sure I'll find a home for it if it doesn't work out
