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.

5 of 5 EXCELLENT Customer Service April 30, 2018
Reviewer: Kyle from Royse City, TX United States  
I have not had a chance to use the FRANS device because it has not arrived yet. My experience with ArmsUnlimited has been strictly with their customer service while the shipping delay is resolved. How they have handled it so far deserves 5 stars. I emailed after hours because I had not received the item after 10 days and tracking info showed it in Vegas. I know it is a busy time in the industry so I understand delays. What is so impressive was I got a human response to my after hour email AND a promise they would figure out the issue by the next day.  Sure enough, the next day I received an email mid morning and the problem was solved on their end, but they also asked if I wanted a refund because of the delay.  I did not want a refund but thought that was very generous to offer. ArmsUnlimited greatly impressed me with their customer service and communication!! Once I get the FRANS I will definitely update my review.
