The new 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. After firing several rounds, the Gen 1 locking lug gets frozen with the carbon deposit and it can no longer be removed.
The Gen 2 reverse thread is easy to remove after firing. The surface is now Black Oxide.The circumference is reduced so that it will match most hand-guards. OD is approx 1.5. Slightly lighter than the Gen 1.
The connector is reverse thread instead of the locking lug. More holes on the CRD body for better control in full-auto compared to Gen 1. This new style is a screw on and is not compatible with Strike Industries or older Gen 1 CRD. Fits: most rifle threads 1/2x28 TPI with 1.5 clearance 223556/22cal.Due to the nature of these parts we require all gun parts to be installed by a licensed armorer.
