I honestly dont see my self needing flash suppression.. I see where if i was in a SHTF scenario shooting at night where i guess it could help.. But lets get real. This rifle will be range/HD/training carbine. I could give 2 ****s about the guy next to me, or someone at the range saying my carbine is loud. Speak it to me guys i have no experience with anything other than a A2 this will be permd on a bcm 14.5 middy with a DD rail more then likely Wanna kill these ads? We can help!
