The Real-Use Review: CMMG, Inc Firing Pin Retainer

The CMMG, Inc Firing Pin Retainer is a small, yet crucial component in the AR-15/M16 platform. CMMG is a well-known manufacturer of AR-15 parts and complete firearms. The retainer is designed to secure the firing pin within the bolt carrier group, preventing it from moving freely and potentially causing malfunctions. Its simple design belies its importance in ensuring safe and reliable operation.

I first started thinking about the CMMG, Inc Firing Pin Retainer when I was building my first AR-15 from scratch. I realized that I needed to source every single part, and this little pin was something that could easily be overlooked. A broken or missing firing pin retainer can stop an AR-15 dead in its tracks.

Upon receiving the CMMG, Inc Firing Pin Retainer, I was struck by its simplicity. It’s a small, unassuming piece of metal. However, it looked and felt solid. I inspected it for any manufacturing defects and found none.

I didn’t do an explicit side-by-side test, but I chose this CMMG retainer over cheaper, no-name options due to CMMG’s reputation for quality. I was prioritizing reliability over saving a few cents.

My first impression was that this was exactly what it needed to be: a well-made, functional part that would do its job without any fuss. There was no excitement involved, just the quiet satisfaction of knowing I had a quality component in my rifle build. It was a small piece of the puzzle, but an essential one.

Real-World Testing: Putting CMMG, Inc Firing Pin Retainer to the Test

First Use Experience

My initial test involved installing the CMMG, Inc Firing Pin Retainer into my AR-15 bolt carrier group during the assembly process.

Installation was straightforward. The pin slid into place easily, securing the firing pin as intended. There was no binding or resistance. The AR-15 functioned flawlessly during the initial range session.

The ease of use was remarkable. There was virtually no learning curve as it is a drop-in replacement component. I found that the CMMG, Inc Firing Pin Retainer worked exactly as expected, with no surprises.

Maintenance is minimal. Simply inspect the pin for any damage during routine cleaning of the bolt carrier group. The CMMG, Inc Firing Pin Retainer seems to outperform some cheaper, less durable options I’ve used in the past on other builds, where the pins would sometimes bend or break after repeated use.
