Let’s Dive into CMMG, Inc Auto Sear Trip And Anti -Bounce Weight Kit, .22 ARC
The CMMG, Inc Auto Sear Trip And Anti -Bounce Weight Kit, .22 ARC is designed to enhance the performance and reliability of your .22LR firearm, especially when used with conversion kits or dedicated .22LR uppers. CMMG aims to provide a cost-effective way to experience a faster rate of fire using readily available and affordable .22LR ammunition. This kit claims to offer improved functionality, particularly in conjunction with certain triggers and full-auto setups.
I was intrigued by the potential to boost the reliability and performance of my .22LR AR-15 build. I’ve had some issues with light strikes and inconsistent cycling, particularly when using a binary trigger. The promise of an anti-bounce weight and a sear trip specifically designed to work with such setups grabbed my attention.
Out of the box, the kit components look simple but well-machined. The anti-bounce weight has a substantial feel, suggesting a quality build. The sear trip appears precisely crafted. It’s a minimalist kit, but the components exude a sense of purpose. Compared to a standard .22LR bolt carrier group, this adds some weight, which I hoped would translate to smoother operation. I considered other buffer weights and reliability kits, but the CMMG kit seemed specifically tailored for my binary trigger application.
My first impression was cautiously optimistic. The parts seemed well-made, and the concept was sound. The potential for smoother cycling and reduced light strikes was exciting. I was eager to see if it would live up to the claims.
Real-World Testing: Putting CMMG, Inc Auto Sear Trip And Anti -Bounce Weight Kit, .22 ARC to the Test
First Use Experience
My initial testing took place at an outdoor shooting range, focusing on a .22LR AR-15 equipped with a binary trigger and a CMMG .22LR conversion kit. The weather was mild and dry. I wanted to gauge the kit’s impact on cycling speed and reliability.
The first few magazines were noticeably smoother. The binary trigger felt more consistent, with fewer instances of hammer follow. I experienced a noticeable reduction in light strikes compared to previous range trips without the kit. However, after approximately 100 rounds, I experienced a couple of failures to extract. This prompted closer examination.
The sear trip was slightly binding within the upper receiver. It wasn’t moving as freely as it should. This might have been causing some inconsistencies. I spent some time adjusting the sear trip. This involved slightly twisting it to improve its freedom of movement. This adjustment seemed to alleviate the extraction issues, at least temporarily.
Extended Use & Reliability
After several range sessions totaling over 500 rounds, the CMMG, Inc Auto Sear Trip And Anti -Bounce Weight Kit, .22 ARC has proven to be a mixed bag. The anti-bounce weight undoubtedly helps reduce bolt bounce and light strikes, especially when paired with the binary trigger. This leads to a more consistent and enjoyable shooting experience.
Durability, however, is a concern. After approximately 300 rounds, the sear trip began to show signs of wear. It started exhibiting slight bending. This resulted in increasing friction within the upper receiver. Some user reviews also mention breakage issues. This suggests the sear trip might be a weak point in the design.
Cleaning and maintenance are straightforward. The parts are easily accessible. A quick wipe-down after each range session has kept them relatively clean. Compared to using the .22LR conversion kit without the CMMG kit, the improvement in cycling consistency is undeniable. However, the sear trip’s durability remains a significant concern that overshadows its benefits.

Performance & Functionality
The CMMG, Inc Auto Sear Trip And Anti -Bounce Weight Kit, .22 ARC aims to improve the cycling consistency and reliability of .22LR AR-15 builds. Especially when used with binary triggers or full-auto configurations. The anti-bounce weight reduces bolt bounce. This minimizes light strikes and enhances the overall shooting experience. The sear trip, when properly adjusted, facilitates smoother cycling and proper sear engagement.
The primary strength lies in the noticeable reduction of light strikes and improved cycling, leading to fewer malfunctions. However, the sear trip’s tendency to bind and its questionable durability are significant weaknesses. The kit does meet expectations in terms of reducing bolt bounce, but falls short in providing long-term reliability due to the sear trip’s design.
Design & Ergonomics
The kit consists of simple, straightforward components. The anti-bounce weight adds a noticeable heft to the bolt carrier group. This weight contributes to smoother cycling. The sear trip is designed to interface seamlessly with the existing trigger mechanism. Proper installation is crucial for optimal performance.
The build quality of the anti-bounce weight feels robust, with a solid, well-machined construction. The sear trip, on the other hand, seems thin and more susceptible to bending or breaking. There is a slight learning curve involved in adjusting the sear trip. Ensuring it moves freely within the upper receiver.
Durability & Maintenance
The anti-bounce weight is likely to last for an extended period. Its simple design and robust construction contribute to long-term durability. However, the sear trip appears to be a weak link. It is prone to wear and potential breakage after a few hundred rounds.
Maintenance involves periodic cleaning of the components and inspection for any signs of wear or damage. If the sear trip becomes excessively bent or damaged, it will need replacement.
Accessories and Customization Options
The CMMG, Inc Auto Sear Trip And Anti -Bounce Weight Kit, .22 ARC doesn’t come with any additional accessories beyond the anti-bounce weight and sear trip. It’s designed to be a drop-in upgrade for existing .22LR AR-15 builds.
The kit is primarily compatible with CMMG .22LR conversion kits and dedicated .22LR uppers. Some users have reported success using it with Fostech Echo triggers. This required some minor modifications, such as cutting off tabs on the sear trip. Compatibility with other accessories depends on the specific trigger and lower receiver configuration.
