Hey Josh, I just received mine and it didn’t fit over the bottom shoulder/ bottom thread, I just used some 100 grit sandpaper wrapped around a sharpie and proceeded to sand the inside of the narrow end of the adapter. Then used the stock a2 flash hider turned upside down and a rubber mallet to seat the adapter down onto the beveled edge. If all else fails you can just snag a thread adapter or buy a new barrel for In Lead We Trust. Honestly that’s what I’m going to do soon they come stock in 1/2x28 TPI with an optional tri-lug already milled into the barrel behind the threads.
