FERFRANS Muzzle Brake Concussion Reduction System


The 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.

The muzzle brake effectively mitigates felt recoil and muzzle movement and with the CRD attached does this while minimizing side blast/concussion and redirects sound to the front of the shooter. It is a two piece modular system that includes (1) very effective high performance muzzle brake and (2) a ported Concussion Reduction Device (CRD) that attaches to the muzzle brake using a quick detach mechanism. 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, recoil feels like a slight, straight to the rear push (it's a softer recoil feel, not the typical sharp kick). It is, of course, a compromise between reducing side concussion versus minimizing felt recoil. We believe we have achieved an optimal balance of sufficient brake/ compensator functionality (muzzle leveling effect) and side concussion reduction. The CRD has a quick detach/attach mechanism to allow you to easily switch back to a full brake whenever you.

Great Product - Been a great run June 19, 2017
Reviewer: Alex from Mesa, AZ  
People at the range will love you because of well this product works.

Bought one a couple years back after blowing a hole in a blanket while shooting prone with my Sig556, worked great on that platform so I got another for my Sig716 DMR. It increases recoil slightly but it's a very predictable linear straight push back with both 5.56 NATO and 7.62 NATO. After 10k+ rounds combined, im only removing them because I will be suppressing both rifles. If they were ASR I would keep them on my rifles.

When using NATO spec ammo even on a 16in and 18in barrel it will create large fireballs.

Good product, installation was problematic March 13, 2017
Reviewer: EB from Wisconsin  
I think the design of the Ferfrans CRS is top flight!  However, thread timing made for a real tightening challenge.  It took several turns of the wrench to align the muzzle device, and I'm pretty sure I exceeded the torque specified.
