It was in Stock


The color coded bags make finding and installing the parts very easy even for a first build. The reason it gets 4 stars is that the finish on several parts was rough and looks a little off compared to my perfect mega arms receiver

Perfect Fit


All components installed easily and fit perfectly in PWS MK2 receiver set. Trigger is not as bad as some parts kit triggers, but will be replaced by Geissele at some point.

some good, some bad


Unit came with an excellent trigger and hammer that could be stoned to an excellent let off. Mine came with a take down pin that was .001+ over sized and thus would fit. I suggest buying the standard CMMG kit and purchase the pivot, take down pins and bolt release separately.
