JMac RRD-4C SLIM 14 Muzzle BrakeM14x1 LH Black

The JMac Customs RRD-4C “Slim” 14mm LH Muzzle Brake is a high-performance, lightweight compensator designed specifically for AK-pattern rifles with 14x1mm left-hand threads. Machined from military-grade 17-4PH stainless steel with a durable matte black nitride finish, this muzzle device delivers exceptional recoil reduction, virtually eliminates muzzle rise, and significantly reduces flash—all in a more compact and streamlined package.

Compared to the original RRD-4C, the Slim version is 23% slimmer (0.885″ diameter vs. 1.150″) and 35% lighter (1.8 oz / 51 grams vs. 2.75 oz), while preserving the same outstanding performance that outperforms many big-box competitors. It adds only 1.5″ to the barrel length (overall length 2.1″ / 53.4mm) for a sleek, balanced profile perfect for competition, tactical builds, or everyday range use.

Key features include top-side cut-outs that vent gases upward to force the muzzle down, providing superior muzzle control and an extremely low flash signature. The .360″ bore is optimized for popular calibers like 7.62×39, 5.45×39, and 5.56, making it ideal for most standard AK platforms (not recommended for .308 or 7.62x54R—choose the standard RRD-4C for those).

Compatibility:

• Russian, Bulgarian, Hungarian, East German, Polish, Romanian AK/AKS/AKM/AKMS
• Yugoslavian/Serbian M64, M70, M72, OPAP, PAP
• Chinese variants with 14mm LH threads

• Does not fit VZ.58 variants

Proudly manufactured in the USA and counts as one 922(r) compliance part for builders.Upgrade your AK with the RRD-4C Slim for faster follow-up shots, better control, and a cleaner, more professional look—without added bulk or weight.
