    Not a Bad Kit

    Would have given a higher rating but I have a few issues. While the handle feels great the fit was not 100%. Required reworking hole to line up with threads in lower. Also had an issue with the adjustment on the stock. Spring does not lock in place on position holes. Will probably replace stock.
