What Makes Geissele Super ACR for Bushmaster ACR, 05-240 Stand Out?
The Geissele Super ACR for Bushmaster ACR, 05-240 isn’t just another trigger upgrade; it’s a complete transformation for the Bushmaster ACR platform. Manufactured by Geissele, a name synonymous with high-performance triggers, this drop-in unit promises to elevate the ACR’s trigger feel to near-match grade levels. What immediately sets it apart is the advertised two-stage design, aiming for a crisp, clean break that far surpasses the mushy factory trigger that often plagues the ACR.
My ACR’s trigger was always its biggest downfall. It felt spongy, unpredictable, and genuinely hindered my accuracy, especially during rapid-fire drills or when attempting longer-range shots. I needed a trigger that offered a distinct wall, a consistent pull weight, and minimized overtravel for better control and ultimately, improved performance.
The Geissele Super ACR arrived in a no-frills package, but the quality was immediately apparent. Holding the trigger assembly, the weight felt substantial, and the machining was clean and precise. Compared to the factory ACR trigger, the Geissele looked like a piece of fine machinery compared to a cast part.
I considered several other options, including aftermarket trigger springs and even a complete custom trigger job from a local gunsmith. Ultimately, I chose the Geissele Super ACR due to Geissele’s reputation, the promise of a drop-in solution, and the two-stage design, which I find ideal for both precision shooting and tactical applications. I wanted the confidence of a known product from a top manufacturer.
My initial impression was overwhelmingly positive. The Geissele Super ACR felt like a premium product, and I was genuinely excited to install it and see how it would improve my ACR’s performance. It promised to be the upgrade my ACR desperately needed.
Real-World Testing: Putting Geissele Super ACR for Bushmaster ACR, 05-240 to the Test
First Use Experience
I installed the Geissele Super ACR at my local shooting range. The installation process, as stated in the product description, requires following Bushmaster’s removal and installation instructions; thankfully, the ACR is fairly easy to disassemble and reassemble. I then immediately headed to the range to put it through its paces.
Testing was done across a variety of conditions. I shot in bright sunlight, under overcast skies, and even during a light drizzle to see how the improved trigger affected my grip and control. The Geissele Super ACR significantly improved my accuracy and confidence in all conditions.
The difference was immediately noticeable. The Geissele Super ACR’s distinct two-stage pull and crisp break were a revelation compared to the factory trigger’s mushy feel. It took a few magazines to adjust to the lighter pull weight, but once I did, my groupings tightened considerably, especially at 50 and 100 yards.
My only initial concern was the reset, which felt slightly longer than I anticipated. However, with more use, I adapted to the reset and no longer found it to be an issue. The immediate improvement in accuracy far outweighed this minor adjustment.
Extended Use & Reliability
After several months of regular use, the Geissele Super ACR has proven to be a reliable and worthwhile upgrade. It has seen action in multiple range sessions, a two-day carbine course, and even accompanied me on a hunting trip. The trigger’s performance has remained consistent throughout, regardless of the round count or environmental conditions.
There are minimal signs of wear and tear. The finish on the trigger itself is holding up well, and the trigger pull remains consistent. The only maintenance I’ve performed is a simple cleaning and lubrication of the trigger assembly during my regular firearm maintenance.
Compared to the factory ACR trigger, the Geissele Super ACR is in a different league. It has transformed my ACR from a decent rifle into a truly capable and enjoyable platform to shoot. It has exceeded my expectations in terms of both performance and reliability.
Breaking Down the Features of Geissele Super ACR for Bushmaster ACR, 05-240
Specifications
The Geissele Super ACR for Bushmaster ACR, 05-240 is a drop-in, two-stage trigger designed specifically for the Bushmaster ACR. It boasts an approximate total pull weight of 4.5 lbs. This is split into a roughly 2.5 lb first stage and a 2.0 lb second stage.
The Geissele Super ACR utilizes the original Bushmaster hammer spring. This is an important point to note as the trigger does not ship with a replacement spring, meaning careful removal and reuse of the original is necessary during installation. The two-stage design is crucial for enhancing accuracy by allowing the shooter to take up slack before committing to the final trigger pull.
Performance & Functionality
The Geissele Super ACR performs exceptionally well. The consistent pull weight and crisp break significantly improve accuracy and reduce the likelihood of unintentional shots. The distinct two-stage design makes it easier to maintain control, especially during rapid-fire scenarios.
The primary strength is the trigger’s overall feel, transforming the ACR’s fire control from its weakest link to one of its biggest assets. A potential area for improvement would be shortening the reset slightly, although I’ve found it manageable with practice. Overall, it meets and exceeds my expectations for a high-performance trigger.
Design & Ergonomics
The Geissele Super ACR is designed for ease of installation and user-friendliness. The build quality is excellent, with precise machining and durable materials. The trigger’s weight is noticeable but not excessive.
Installation requires following Bushmaster’s instructions for trigger removal and installation, but the process is generally straightforward for anyone familiar with AR-platform firearms. There’s a slight learning curve to master the two-stage pull, but the benefits in accuracy are well worth the effort.
Durability & Maintenance
The Geissele Super ACR is built to last. With proper care and maintenance, it should provide years of reliable service. Maintaining the trigger involves occasional cleaning and lubrication.
The durable construction and high-quality materials contribute to its longevity. I anticipate this trigger lasting for the lifetime of my ACR.
Accessories and Customization Options
The Geissele Super ACR for Bushmaster ACR, 05-240 does not come with any additional accessories. The primary customization option is the ability to adjust the trigger pull weight within a limited range by swapping out the factory hammer spring for a different spring weight (although this is not officially supported by Geissele and may affect reliability).
The Geissele Super ACR is compatible with most standard ACR components. This ensures seamless integration with existing accessories like grips, stocks, and optics.
