JMac Customs RRD-4C “12” Muzzle Brake for SAIGA and VEPR Shotguns

This article was originally posted on Thefirearmblog.com

JMac Customs has released the shotgun version of their RRD-4C series of muzzle brakes/muzzle rise compensators. The versions for AK-style rifles have gained a fairly good reputation among AK enthusiasts. The success of the general design has eventually lead to designing the scaled-up version for Vepr 12 and Saiga 12 shotguns.

Despite the humongous appearance, the RRD-4C “12” weighs 5.5oz. Looks like they did a good job of reducing the amount of unnecessary material everywhere it is possible. Note the chamber wall thicknesses and the lightened bottom portion of the muzzle brake.

The RRD-4C “12” is made of 17-4ph stainless steel and has a black nitride finish. It is 3.5″ long (including the locking collar). The width and height are 1.75″ and 1.4″ respectively.

The RRD-4C “12” comes with the locking collar. It is available through the JMac Customs’ website for $142.95.

I don’t have any experience with this particular muzzle device, but I’ve shot a similar one installed on a Saiga-12 shotgun. Large brakes like this make a huge difference. They make the shooting more fun by significantly reducing the recoil of 12 gauge and making follow up shots much easier. That being said, I think the RRD-4C “12” muzzle brake should also be very useful for the competition shooters.
