So, I've been thinking that my little M4gery needs a big brother. I'm considering building up an AR10 carbine and also putting together another upper for precision work.

The base gun would be the AR10 carbine flattop. I'd add the Larue rail and lo-pro gas block. My question is, would it be worthwhile to put a KX3 on the front? I'd like to redirect some of that muzzle blast away from myself, but I don't want to overgas the weapon.

Anyone with experience or thoughts?
