I was thinking of doing a first AR build. Never done this and the number of barrels, receivers and buffers is mind boggling. Is there a standard barrel thread for most receivers?
I know the gas block has to match the Barrel measurement at the gas outlet port but I don’t seem to find anything on the Receiver side of the barrels?
