On my 11.3" build (which is an 'other' weapon, as opposed to a pistol...hence the VFG), I went with a Midwest Industries Blast Diverter to help keep blast and concussion forward, but it's still a pretty small unit not much bigger than your typical A2 cage, so it doesn't add any considerable size and weight as other blast-cans or forwarding devices.

A bit louder than a some of the bigger can-type blast diverters, but still a considerable help for the shooter and to the immediate side for blast/concussion. Good for a sleek grab-n-go gun that you're not planning on suppressing, and 5.56/.223 recoil is so minimal that I don't feel like I'm missing any controllability without a muzzle brake or comp.
