Thank you Hmh, The juggernaut is for the m1a and m14. But looking at photos of it gives me a good idea of what to do. I'm just not positive on how I want redirect the spent rounds, since they will be coming out right near my face haha. On the m1 carbine the spent rounds come straight up and out falling to either side on the way down depending on which say the shooter leans. Or at lest thats how it is on my m1. I believe the new Famas uses just a curved strip of metal to redirect its rounds but makes a ton of noise
