Action Tuning Kit, Radial Delayed Blowback
Fine tune your Radial Delayed Blowback™ pistol or carbine with the Action Tuning Kit. Whether you want the smoothest shooting carbine possible or are looking for added reliability while shooting hotter loads or suppressed, CMMG’s Action Tuning Kit gives you the added flexibility to make your CMMG® perform exactly how you like it.
Small, Medium, and Large weights allow for you to test and find the right weight for your setup. There is no universal answer for which works best. Barrel length, ammo selection, and suppressed or not play a large role in determining your weight.
Included:
– 1oz, 2oz, and 3oz weights
– (3) .250″ x .625″ roll pins
