    Great company – It was a pleasure doing business with you. You did everything I asked of you pertaining to my order. I would most certainly do business with you again.

    Good Quality – I’ve ordered 2 uppers from mid state and I’ve loved both of them! They are really nice for me especially bc I’m left handed and they offer alot of left handed options.Both uppers have been reliable and accurate so I can’t complain but the dang dust cover will not stay closed on one them haha no big deal tho as I can fix this. Would recommend Mid state firearms to anybody!

    Upper Review – Love how short it is. Very durable

  5. MP

    Perfect – Forget my initial review I get so many compliments on the AR and it feels great I love the ultralight handguard. If you want it loud get the competition muzzle brake, no one at the range believes me when I say it’s 5.56. About 500 rounds so far never skipped a beat
