I have a question for you AR Gurus. (just out of curiosity) If I use a 9mm A2 Birdcage (1/2x28) flash hider on a 5.56. Does it do the same job as a regular 5.56 A2? as far as flash suppression? since the hole in 9mm A2 is larger? im I’m guessing that I’ll work the same.
Should be fine and do the same job.
