The RRD-2C is a shortened version of the RRD-4C by removing the 2 smallest ports creating a more compact package!

At 2.23" it still adds 1.53" and can be permanently attached to a 14.5" barrel to achieve 16" OAL.

Can't say enough about RRD-2C KeyMicro. I use this with a thread adapter on my M92 ZPAP. JMac makes the stuff we want and need. I also have the normal brake version in 14x1L on my SAM7R and it is also a masterpiece.
