Let’s Dive into CMMG, Inc AR15 Disconnect
The CMMG, Inc AR15 Disconnect is a critical component in the AR-15 trigger group, responsible for precisely releasing the hammer after the sear is disengaged. A properly functioning disconnect ensures safe and reliable semi-automatic fire. For just $8.99, it represents an inexpensive but vital piece for any AR-15 build or repair.
My need for this part stemmed from a recent issue with a custom AR build where I was experiencing occasional “doubles” – two rounds firing with a single trigger pull. This can be incredibly dangerous and pointed directly to a faulty disconnect. After some research, I decided to try the CMMG, Inc AR15 Disconnect due to CMMG’s reputation for quality and reliability.
Upon receiving the part, I immediately noticed its clean machining and precise finish. The disconnect felt solid and well-made, a good sign for its intended function. It appeared identical to the factory disconnect I was replacing, which gave me confidence in its compatibility.
I considered options from Brownells and Geissele, but ultimately chose the CMMG part due to its affordability and readily available positive reviews discussing its reliability in standard AR builds. Geissele parts, while excellent, are overkill for a standard semi-auto function, and this CMMG component seemed the right balance of value and performance. My initial impression was optimistic; it looked like a quality replacement part that would resolve my rifle’s issues.
Real-World Testing: Putting **CMMG, Inc AR15 Disconnect** to the Test
First Use Experience
My initial testing took place at my local range, where I focused on diagnosing the “doubling” issue. I installed the CMMG, Inc AR15 Disconnect into my AR-15’s trigger group, reassembled the lower receiver, and then function-tested the rifle with dummy rounds before loading live ammunition. With the new disconnect installed, I carefully tested the trigger pull, noting the reset and overall feel.
I ran several magazines through the rifle, deliberately varying my firing rate and grip to replicate the conditions under which the issue previously occurred. The CMMG disconnect performed flawlessly, preventing any further instances of doubling. It provided consistent and reliable operation throughout the entire range session.

Over the past three months, I’ve put several hundred rounds through the rifle with the CMMG, Inc AR15 Disconnect installed. It has continued to function without any issues whatsoever. There are no visible signs of wear or deformation on the disconnect itself.
Maintenance is straightforward; I simply clean and lubricate the trigger group as part of my regular rifle maintenance routine. The CMMG disconnect has significantly outperformed my expectations. I no longer have any concerns about unsafe firing behavior, and the rifle feels much more reliable overall.
