I just picked up my M&P 15T from my FFL after ordering online and noticed that the HBAR 1 in 8 that came with it does not have any threads on the end for a flash suppressor. If I get these machined on, am I likely to have trouble as the threads are not then nitrided?
What threads are needed to allow adding standard suppressors?
