    I love the parts kits and the fast service to ship but I’m disappointed in the using the usps for shipping,my parts shipped Monday and still in ohio,FedEx or ups is much better than usps priority mail because I’ve stopped using other companies for the slow shipping by the postal service.

    Solid parts kit, smooth installation. Only catche was that the kit I received was missing the pistol grip bolt and trigger guard. Quick email to the company and they immediately sent me the required parts. Overall great customer service.

    Parts all fit in perfectly and everything was there. One of the roll-pins had snuck out of one of the smaller baggies but stayed with everything else.

    For a low-budget build this is fantastic! The stock looks and feels cheap but it functions fine and can always be upgraded later. Great buy.
