I have been thinking about getting a suppressor for my preban Bushmaster Shorty. I'm just not sure which model to get. I've looked at Gem Tech, Advanced Armament and AWC(pricey). I like the Gem Techs but one of the AA models looked nice too. Can anyone give me some advice on which will hold up longest and suppress the best? Also I would rather have a screw on and not a QD. I just don't like things that move too much. There's just more stuff to wear down and let Mr Murphy in to play. Any other advice that you might think would help would be appreciated too. Thanks.
