Rainier Arms is offering these Ferfrans CQB Modular Brake Systems right now and I thought it was an interesting concept. It's basically a 3 port brake with a shroud. Since everyone knows that it can be brutal standing next to the guy shooting a brake, this muzzle device includes what is called a Concussion Reduction Device, for the times you don't want to rattle your buddies teeth next to you. I'll be curious to read the reviews on this one.
