I've shot a sig AR pistol in.556. They're to loud and the muzzle flash in 7 inch will sunburn you in 30 rounds. Looking for an alternative.

9mm or.30 blackout seems to be it. An AR pistol properly accessorized (EO Tech & a light) in the right cal. 556 isn't it for my application. I have a halo site mounted on a ruger 44 carbine and its a deer killing machine.

Looking for the 100 yard PDW.

Thanks for the opinions.
