    Excellent products

    Used this for a 12.7 x 45 build using a BCA upper. Great fit, great match and excellent price. Will be back in the future.

    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.

    Great fit, easy install

    Everything necessary to build a stripped lower, some grit in the trigger but thats not unexpected with this price point. It does what I want it to do.
