Ferfrans CQB Modular Muzzle Brake System

[UWone77]

Rainier Arms (https://www.rainierarms.com/?page=shop/detail&product_id=4189) is offering these Ferfrans CQB Modular Brake Systems (http://www.ferfrans.net/products) 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.

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

I sort of want to test this thing out, I don't know though...

That's a good looking. However, the million dollar question, how does the brake shoot with and without the shroud?

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

Yep that's about right. And how does she run?

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:

it is really nice to see people to take the time to do pictures like this. it just really help guys like me see and understand how "new" products work.

really awesome design.....but....how much impact can the outer shroud/shield take when mounted??
