    How the build went

    This was my 5th build and first time using this kit. The buffer retainer did not work period. When pressed in the lower it would just stick I would have to pull it out with a needle nose. I tried a buffer retainer out of a different kit and it worked perfect so I know the lower is not the issue. The disconnector spring also did not fit correctly. It seems to be working for now but I will be changing it out. For the price I do like the stock. I am using it on a can launcher build so this kit worked great for that but would not use it on anything fancy.

    Alpha Kit

    Had trouble with the website so I called. The employees were more than helpful and got everything squared away for me. Shipped and arrived fast! Kit is of good quality and runs nicely on my 6.5 Grendel! Second kit from them and love both of them!

    Great kit. Fuctions perfectly. Installed into an anderson lower paired with a davidson upper an bear creek bcg and parts I sourced here and there and built a great shooting 7.62×39.

    Anderson LPK

    The kit went together great. My biggest complaint is that the castle nut must not have been tapped correctly as it will not sit anywhere near flush. There is a little more wobble in the butt-stock than I would like. Everything else though gives this a 4 star.

  8. Brian –

    Not real pleased

    Threads on castle not are very sloppy and either reciever end plate or buffer tube needs work, hard to keep straight when tightening not, quality control needs attention

    Great Value for what you get

    Purchased this kit to complete my stripped lower. All the parts fit nicely took 30min to complete. Only issue is that the buttstock has slight rotational movement My AR 7.62x39build looks really good
