Almost done building 11.5" 556 SBR. I was set on one of the surefire cans but after reading a little there are alot of good options. I was about to purchase SF3P flash hider but not 100% I'm going with surefire now. Looking for a can thats relatively short and relatively lightweight. Also want something that quick detach option. No direct thread. This will be my first suppressor so I have no experience with them. Any advice will be much appreciated.
