Geissele AR-15 Super 42 Buffer Spring/Buffer Combo For Carbine Receiver Extensions Review

Let’s Dive into Geissele AR-15 Super 42 Buffer Spring/Buffer Combo For Carbine Receiver Extensions

The Geissele AR-15 Super 42 Buffer Spring/Buffer Combo For Carbine Receiver Extensions is a drop-in upgrade designed to enhance the performance and reliability of your AR-15. Manufactured by Geissele, this combo promises to reduce felt recoil, eliminate the annoying “sproing” sound often associated with standard buffer springs, and improve overall rifle cycling. As someone who’s spent years fine-tuning AR platforms for both competition and duty use, I was eager to see if this upgrade lived up to the hype, especially at its price point.

I was experiencing inconsistent cycling with some of my AR builds, particularly when switching between different ammunition types. The stock buffer system felt like a weak link, often contributing to excessive recoil and that characteristic metallic reverberation after each shot. I hoped the Super 42 would provide a smoother, more consistent, and ultimately more enjoyable shooting experience.

Upon unboxing, the first thing that struck me was the quality of the components. The braided wire of the spring looked and felt robust, a clear departure from the standard mil-spec spring. The buffer itself felt solid and well-machined. It was immediately apparent that this wasn’t just another generic AR part; Geissele’s attention to detail was evident.

I considered other options like the JP Enterprises Captured Spring System, but the Geissele offered a compelling balance of performance and ease of installation. I’ve also used standard mil-spec buffer and spring combinations in the past and wanted to step up the performance. Plus, the numerous positive reviews about its noise reduction capabilities swayed me toward the Super 42.

My first impression was one of cautious optimism. The build quality was undeniably impressive, and the promise of smoother cycling and reduced noise was enticing. I was excited to get it installed and see if it translated to a tangible improvement on the range.

Real-World Testing: Putting Geissele AR-15 Super 42 Buffer Spring/Buffer Combo For Carbine Receiver Extensions to the Test

First Use Experience

I tested the Geissele AR-15 Super 42 Buffer Spring/Buffer Combo For Carbine Receiver Extensions at my local outdoor shooting range. The weather was mild, around 70 degrees Fahrenheit, and the conditions were dry and sunny. I installed the Super 42 in my go-to 16-inch AR-15 chambered in 5.56 NATO.

The difference was immediately noticeable. The cycling felt smoother, and the felt recoil was perceptibly reduced. The rifle felt more controlled, especially during rapid fire. Most impressively, the “sproing” sound that I’d grown accustomed to was virtually gone.

There were no immediate issues after the first use. The installation was straightforward, and the rifle cycled flawlessly with both 55-grain and 62-grain ammunition. The most surprising thing was the reduction in muzzle rise, even with relatively hot loads.

Extended Use & Reliability

After several months of regular use, the Geissele AR-15 Super 42 Buffer Spring/Buffer Combo For Carbine Receiver Extensions has proven to be incredibly reliable. I’ve put several thousand rounds through the rifle, and the system continues to perform flawlessly. The difference between the Super 42 and a mil-spec buffer spring is like night and day.

There are no significant signs of wear and tear. The spring still feels strong and consistent, and the buffer shows no signs of deformation or damage. I clean the buffer and spring every few hundred rounds as part of my routine rifle maintenance. It is as easy as cleaning any other spring and buffer.

Compared to my previous experiences with mil-spec buffer systems, the Geissele Super 42 is a clear upgrade. It significantly improves the overall shooting experience, enhancing control, reducing recoil, and eliminating that annoying spring noise. It has completely exceeded my expectations.

Breaking Down the Features of Geissele AR-15 Super 42 Buffer Spring/Buffer Combo For Carbine Receiver Extensions

Specifications

The Geissele AR-15 Super 42 Buffer Spring/Buffer Combo For Carbine Receiver Extensions is designed for standard AR-15 carbine receiver extensions.

These specifications are vital because they directly impact the rifle’s cycling characteristics and felt recoil. The braided spring design acts as a harmonic dampener and energy absorber, helping to smooth out the cycling process and reduce the impact felt by the shooter. The increased spring force also ensures reliable cycling, even with dirty or underpowered ammunition.

Its strengths lie in its braided spring design, which effectively reduces recoil and eliminates spring noise, and its robust construction ensures long-term reliability. A minor weakness might be the price point. While not exorbitant, it is more expensive than a standard mil-spec buffer system.
