  • Pretty good, but...

    Posted by Bendigo on May 11th 2019

    Does not come with muzzle device in webpage picture. Mine was delivered with AAC 3 prong ratchet device.
    Forgrip top rail and receiver rail out of alignment. Gunsmith estimated $150.00 to align them.
    Fit and finish is very good. No trouble shooting with it.
    Except for minor issue, it is a good buy._____ Nots: We have changed the image to match the correct brake.
