Okay, so I finished my first AR build at the weekend, and I must admit that I have dome more time researching my potential second build that I have shooting the first.
I'm thinking of buying a 9mm upper and using an EndoMag 9mm magazine. Anyone have experience using one of these conversion...
For those of you who have built featureless ARs; Most barrels come threaded, how did you handle that? ..... destroy thread with file, weld on thread cap, JB weld on thread cap?
