Ferfrans CQB Modular Muzzle Brake System
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.
Check out Ferfrans on their website here or http://www.ferfrans.net/products
The new Ferfrans CQB Modular Muzzle Brake System is a two part system consisting of the performance MUZZLE BRAKE MOUNT + CRD (Concussion Reduction Device) which features a built in quick attach/detach mechanism.

Brake Thread Pattern - 1/2x28
Caliber - (.223/556)
CRD (Concussion Reduction Device) Specs:

Width - 1.6" Diameter
Total weight of the system combined is 10.4 ounces.

If you can get the measurements just right would almost look like an extension to the rail. This would look nice on a pistol build with minimal space between rail and muzzle device

^--- reviews are a must! I like the look of the rail extension. Who wants to be the guinea pig?

Fair enough.
As you can see from the pic, the CRD has strategically placed side ports that allow the muzzle brake to retain its compensator functionality as opposed to brake shields that cover the brake and negates its function.
With the CRD attached, you will feel more recoil than without the CRD because most of the propellant gasses are now being directed forward. But recoil feels like a slight, straight to the rear push (it's a softer recoil feel, not the typical sharp kick). The key, however, is that you still have a flat shooting rifle even with the CRD on with just a hint more felt recoil.
It is, of course, a compromise between reducing side concussion versus minimizing felt recoil. I believe an optimal balance of sufficient brake/ compensator functionality (muzzle leveling effect) and side concussion reduction has been achieved. The CRD has a quick detach/attach mechanism to allow you to easily switch back to a full brake whenever you.
So speaking of brake only function, it is a quintessnetial 3 port brake and, IMHO, opinion owrks just as good, if not slightly better at keeping the rifle shooting flat and minimizing felt recoil in full-auto compared to the best brakes on the market.
Here are a couple videos showing how it works:
