Real-World Testing: Putting CMMG, Inc External 1 3/8in Retaining Ring to the Test
First Use Experience
I tested the CMMG, Inc External 1 3/8in Retaining Ring immediately after installing it into my rebuilt CMMG AR-15 bolt carrier group. The testing occurred at an outdoor shooting range, subjecting the rifle to typical semi-automatic firing cycles. I also performed several dry-fire drills and manipulated the charging handle repeatedly to simulate common operational scenarios.
During testing, the retaining ring performed flawlessly under normal conditions. The weather was mild, and the rifle was clean and properly lubricated. No issues were observed with the bolt carrier group’s function, and the retaining ring appeared to maintain its position securely.
Installation was relatively simple, although working with small parts always requires patience and precision. There were no unexpected challenges or surprises during the installation or initial use. It fit as expected and did its job reliably.
Extended Use & Reliability
After several months of consistent use, the CMMG, Inc External 1 3/8in Retaining Ring continues to perform admirably. I have fired several hundred rounds through the rifle since installing it. I have observed no signs of wear, deformation, or loosening of the retaining ring within the bolt carrier group.
The durability of the ring is impressive. Despite repeated firing cycles and exposure to heat and carbon buildup, it has maintained its structural integrity. Maintenance is minimal; cleaning the bolt carrier group as part of my regular firearm maintenance routine is sufficient to keep the retaining ring in good condition.
Compared to previous experiences with lower-quality retaining rings that have failed or deformed prematurely, the CMMG ring significantly outperforms them. Its reliability and durability provide peace of mind, knowing that this small but critical component will not be the weak link in my firearm system. It definitely exceeded my initial expectations based on my past frustrations with inferior products.
Breaking Down the Features of CMMG, Inc External 1 3/8in Retaining Ring
Specifications
- Product Name: CMMG, Inc External 1 3/8in Retaining Ring. This clearly identifies the item.
- Type: External Retaining Ring. This denotes its use on a shaft or similar cylindrical component.
- Inside Diameter: 1 3/8 inches. This is the most critical dimension for ensuring proper fitment.
