    Kinda cheap but it all fit.

    Buttstock looks like cheap plastic. Maybe I can sand the seam somehow. Must be made in China. The parts all fit. The trigger was excellent. Only knocked a star off because I think the buttstock will discolor when it gets hit and the seam down the middle.

    A2 stock and parts kit

    I got the A2 stock and own parts kit and out it on a Anderson lower. The finish on all the lower parts were deep nitrate it appeared. All was perfect. The a2 stock was also perfect. It also came with the compressed road inside to make for a soft storage compartment. Super happy with this product. I will say don’t forget to pick up some blue locktite for installing the rear buffer tube

    Some good, some bad

    Everything went together fine, all internals good. Had a problem with the buffer and spring. Would short stroke me every shot. Bought new buffer and spring from different company and everything works fine.
