    11.5 inch barrel flash mitagation options

    I'm running an A2 flash hider on my 11.5 I load my own ammo using H335 Powder which nearly is identical to M193 powder.

    That being said I'd like to see if it is worth getting a different flash hider to minimize flash.

    Yep, those will all do the trick.

    If you are planning on running it suppressed, it might be a good time to decide on what direction you want to go, and buy the applicable FH.

    Just be aware that most 3-prong flash hiders will "ping" when fired, which can be annoying to some. I believe SilencerCo has one with varying prong lengths that greatly reduces the tuning-fork effect, FWIW.

    I run a SilencerCo Trifecta flash hider on a BCM 11.5. It doesn't ping, at all. The flash suppression is better than when I had an A2 on it, but it definitely depends on the ammo.

    FWIW, I run a vortex FH on my 11.5's and they have WAY less muzzle flash in low light than any of my handguns. Agree with the poster above on the 3-4 prong FH's being best for pure flash redux.

    Switch that GOD AWFUL powder!!! That crap is horrendous. I only run that crap when I want to enhance flash at night shoots for the foolish fun factor.

    I hear no discernible ping from my 249F equipped rifle either. I was expecting to hear a ping as well after reading about it on the Internet. If it is there my ears don't hear it at least.

    Concur with the recommendations above, including the powder switch.

    I like H322, XBR, and TAC.

    I've only used the AAC blackout and SilencerCo trifecta. The AAC seemed to be different from rifle to rifle. Some ping loud as heck, and continue ringing well after the shot. Others are hardly noticeable above the bang. I wonder if it has to do with using a crush washer for the non-suppressor mount version versus no washer at all for suppressor use, and then carbon buildup.

    I have two trifectas, and both have been completely silent from day one on 11.5" and 18" barrels.
