Real-World Testing: Putting CMMG, Inc AR-15 Bolt Rehab Kit to the Test

First Use Experience

I put the CMMG, Inc AR-15 Bolt Rehab Kit to the test during a routine maintenance session on my primary AR-15. This rifle sees regular use at the range and in training scenarios. My goal was to proactively replace the ejector and extractor components, the parts most prone to wear and tear.

Extended Use & Reliability

After several hundred rounds fired with the CMMG, Inc AR-15 Bolt Rehab Kit components installed, my AR-15 continued to perform flawlessly. The replacement parts showed no signs of premature wear or degradation. Regular cleaning and lubrication kept everything running smoothly.

The durability of the replacement parts appears to be excellent, holding up well under moderate use. I’ve experienced no malfunctions related to the replaced ejector or extractor. This speaks volumes to the quality of materials and manufacturing.

Maintenance is simple. Standard AR-15 cleaning procedures apply, with regular inspection of the ejector and extractor recommended. The CMMG kit has definitely outperformed my expectations, providing a reliable and cost-effective solution for bolt maintenance.

Breaking Down the Features of CMMG, Inc AR-15 Bolt Rehab Kit

Specifications

The CMMG, Inc AR-15 Bolt Rehab Kit includes:

• Ejector Spring: Powers the ejector, providing the necessary force for reliable ejection.
• Ejector Roll Pin: Secures the ejector within the bolt.
• Extractor: The claw-like component that grabs the rim of the cartridge, pulling it from the chamber.
• Extractor Spring with Buffer: Provides tension to the extractor, ensuring a firm grip on the cartridge.
• Extractor Pin: Secures the extractor in place.
