5 of 5 9mm BCG December 20, 2015
: Danny M  
All the Parts I bought from Mas for my 9mm pistol build are working great, I had no problems what so ever with the BCG. I always thought that you had to have a special hammer to build a 9 but I foundout while searching for parts that the ones that Mas sold would work with a standard trigger. That allowed me to use a drop in hammer that I already had so no I've got a sweet little 9mm AR pistol with a 3.5 lb trigger pull.
