KNS Precision Reduced-Power AK Recoil Spring Review

First Impressions of KNS Precision Reduced-Power AK Recoil Spring

The KNS Precision Reduced-Power AK Recoil Spring promises a simple solution for fine-tuning the cycling of your AK-pattern firearm, especially when paired with an adjustable gas piston. As someone who’s tinkered with AKs for over a decade, seeking that sweet spot between reliability and recoil mitigation, this caught my attention. The promise of better subsonic cycling alone made me curious.

My journey to this spring started with persistent over-gassing issues on my Galil ACE pistol. Even with an adjustable gas piston installed, the recoil was still harsher than I desired, and consistent subsonic cycling felt like a pipe dream. I’d experimented with heavier buffers in AR platforms, but the AK system requires a different approach.

Upon unboxing, the KNS Precision Reduced-Power AK Recoil Spring is visually unremarkable. It’s a grey-finished spring, seemingly similar in length and construction to a standard AK recoil spring. But closer inspection reveals a noticeably lighter feel when compressed. This immediately instilled a bit of apprehension. Would it be too light to reliably cycle standard ammunition? Compared to a Wolff extra-power spring I use in another AK, the difference was significant. I chose this spring specifically to accompany my KNS gas piston, hoping for optimal synergy.

Initial impressions were a mix of cautious optimism and a healthy dose of skepticism. Was I excited? Perhaps intrigued is a better word. Disappointed? Not at all. Surprised? Maybe by how simple the solution seemed.

Real-World Testing: Putting KNS Precision Reduced-Power AK Recoil Spring to the Test

First Use Experience

My initial testing ground for the KNS Precision Reduced-Power AK Recoil Spring was a local outdoor shooting range, known for its varied conditions. I brought my Galil ACE pistol chambered in 7.62×39, equipped with the KNS Precision adjustable gas piston. I tested with a mix of standard full-power ammo, and some rather expensive subsonic rounds. The weather was typical for the area: dry, dusty, and around 75 degrees Fahrenheit.

Installation was incredibly straightforward: tool-less and reversible, just as advertised. With the spring installed, the first few magazines of full-power ammunition cycled without issue. However, the difference in recoil impulse was subtle but noticeable. It felt slightly softer, but I attribute this mostly to the gas piston working in tandem. When I switched to subsonic ammunition, I finally began seeing the potential. Prior to the spring swap, my Galil choked every other round with subsonics. With the KNS Precision Reduced-Power AK Recoil Spring, it managed to cycle nearly every round, with only a couple of failures to lock back on an empty magazine.

Extended Use & Reliability

After several months of use, and hundreds of rounds fired, the KNS Precision Reduced-Power AK Recoil Spring continues to perform as expected. I haven’t observed any significant wear and tear on the spring itself, and the grey finish has held up remarkably well. My Galil pistol’s performance with subsonic ammunition has significantly improved, although not flawlessly.

Maintaining the spring is as simple as any other AK part: a quick wipe down with a lightly oiled cloth. I have not noticed any compression fatigue or changes in performance over time. Compared to previous setups, especially when trying to run subsonic ammunition, this setup is a massive improvement in reliability and shootability.

Breaking Down the Features of KNS Precision Reduced-Power AK Recoil Spring

Specifications

• Manufacturer: KNS Precision. A reputable name in AK aftermarket parts.
• Color: Grey. A neutral finish that blends in with most AK platforms.
• Gun Make: Compatible with Israel Weapon Industries (IWI), AK-74, and AK-47. Versatile application across many AK variants.
• Gun Model: IWI Galil, AK-74, AK-47. Covering a wide range of popular models.

The specifications confirm the KNS Precision Reduced-Power AK Recoil Spring’s intended use: to refine AK cycling, especially when combined with an adjustable gas system. Its compatibility with multiple platforms makes it a worthwhile consideration for most AK owners.

Performance & Functionality

The primary function of the KNS Precision Reduced-Power AK Recoil Spring is to reduce the force required to cycle the action of an AK-pattern firearm. This is particularly beneficial when using lower-powered ammunition, such as subsonic rounds, or when trying to fine-tune an over-gassed system. The spring accomplishes this reasonably well, as seen in my testing with subsonic 7.62×39 ammunition.

The main strength is its ability to improve cycling consistency with low-powered ammunition. A potential weakness is the possibility of under-cycling with standard or higher-powered ammunition in firearms that are not already properly gassed. It largely meets expectations, especially when paired with the KNS adjustable gas piston.

Design & Ergonomics

The design is simple: a drop-in replacement for the factory recoil spring. Build quality appears solid, with a consistent finish and no obvious defects. The weight difference is noticeable compared to a standard spring, contributing to the reduced cycling force.

The KNS Precision Reduced-Power AK Recoil Spring is incredibly user-friendly, requiring no specialized tools or gunsmithing skills for installation. There is virtually no learning curve.

Durability & Maintenance

Based on several months of use, the KNS Precision Reduced-Power AK Recoil Spring appears to be reasonably durable. Its long-term lifespan will depend on the specific firearm and ammunition used. Maintaining the spring is simple: clean it with a brush and lightly oil it as part of routine firearm maintenance.

Accessories and Customization Options

The KNS Precision Reduced-Power AK Recoil Spring does not come with any accessories. However, it is designed to work in conjunction with other AK aftermarket parts, most notably adjustable gas pistons. It is also compatible with a wide range of AK-pattern firearms and accessories.
