Real-World Testing: Putting CMMG, Inc Receiver Extension Kit, Pistol Length to the Test

First Use Experience

I initially tested the CMMG, Inc Receiver Extension Kit, Pistol Length at my local indoor shooting range. The range provided a controlled environment to assess the kit’s performance with different ammunition types. I ran several magazines through my AR-15 pistol, focusing on smooth cycling and any potential malfunctions.

The kit performed flawlessly during the initial range session. There were no issues with cycling, and the felt recoil was manageable for a pistol caliber carbine. The pistol length buffer system seemed to effectively dampen recoil and prevent excessive muzzle rise.

The installation was straightforward, and I didn’t encounter any difficulties, even without specific instructions. I had previously installed other AR-15 buffer systems, so I was familiar with the process. No issues were experienced during first use.

After several months of use, the CMMG, Inc Receiver Extension Kit, Pistol Length has continued to perform admirably. I’ve taken the AR-15 pistol to several outdoor shooting ranges and even used it during a training course in a somewhat dusty environment. The kit has held up remarkably well, showing minimal signs of wear and tear.

The finish on the receiver extension has proven to be durable, resisting scratches and abrasions. The buffer and spring have maintained their integrity, with no noticeable degradation in performance. I’ve cleaned the kit after each range session, which involves wiping down the receiver extension and applying a light coat of oil.

Compared to other AR-15 buffer systems I’ve used in the past, the CMMG kit has proven to be more reliable and durable. I have experienced failures with other systems. This kit’s consistency has been outstanding.
