JMAC CUSTOMS RRD 2 PORT COMPENSATOR 28 SLIM 9 1/2-28"

Top takeaways

The RRD-2C is a compact version of the RRD-4C, designed to reduce recoil by removing the two smallest ports for a more compact size.
It's made from 17-4ph Stainless Steel with a Black Nitride finish, has 1/2-28 threads, and is intended for 9mm projectiles with a 10mm bore.
Not recommended for barrels shorter than 10.5 inches when used with rifle calibers, as high rates of fire can cause damage to the compensator.

Description:

Introducing the JMAC Customs RRD 2 Port Compensator – Slim, Compact, and Effective!

The RRD-2C is a sleek and compact version of JMac’s renowned RRD-4C muzzle brake. Designed for those who seek performance without bulk, the RRD-2C offers a shortened profile while effectively mitigating recoil.

Product Features:

Weight: 1.34 Ounces
Threads: 1/2-28
Bore: 10mm
Material: 17-4ph Stainless Steel
Finish: Black Nitride
Bore Machined For: 9mm projectiles

Note: The RRD-2C is not intended or recommended for use with barrels shorter than 10.5” when used with rifle calibers. During testing with rifle caliber ammunition, JMac discovered that high rates of fire, such as full auto or “mag dumps,” could lead to damage due to excess heat, pressure, and gases from unburnt powder on shorter barrels.
