No complaints


Finish is complete with no thin spots. Threads are well cut and were not rough when mated to a PSA lower. The adjustment rail had a little roughness on the outside but nothing worth subtracting a star for - it is still functional.

Got my kit quick and it fits my tactical BMS Minimalist Stock great. Too bad I live in California where tactical means it automatically kills people just by looking at it.
