OK, to start with, I can't presently get one in my state, but I'm hoping to have an address in a free state eventually. I'd like to mount a suppressor on my 22" barreled M1A. My two priorites would be effectiveness of the suppressor and accuracy at distance. Weight and price are secondary. Can anyone give me any advice on which ones would be best suited to my parameters? I've been looking at the offerings from Gemtech, Surefire, AAC, and YHM, Are there any others that I should be considering?
