First Impressions of Kaw Valley Precision Extra Power 17-4 SS Pistol Caliber Carbine Recoil Spring
Pistol Caliber Carbines (PCCs) chambered in 9mm, .40 S&W, .45 ACP, and 10mm are incredibly fun to shoot, but they can be notoriously hard on the AR-15 platform they are built on. A poorly tuned blowback system can lead to accelerated wear and tear, and even component breakage, particularly in the lower receiver. That’s where the Kaw Valley Precision Extra Power 17-4 SS Pistol Caliber Carbine Recoil Spring comes into play, promising to tame these beastly PCCs and extend the life of your firearm.
My journey to this particular recoil spring began with a desire to optimize my 10mm AR PCC build. Recoil felt a bit too snappy, and I noticed some excessive bolt bounce, which are telltale signs that the system wasn’t running as smoothly as it could. I’d heard whisperings of “heavy buffers” and “extra power springs” being the key to a happy PCC, so I decided to dive in and explore my options.
Upon receiving the Kaw Valley Precision Extra Power 17-4 SS Pistol Caliber Carbine Recoil Spring, I was immediately impressed by its clean, stainless steel finish. The spring felt robust and noticeably stiffer than the standard carbine spring it was intended to replace. The build quality appeared excellent, suggesting it could withstand the rigors of repeated cycling in a blowback system.
I considered a few other options before settling on the Kaw Valley Precision spring. I looked at springs from JP Enterprises and Sprinco, known for their high-performance AR components. Ultimately, the Kaw Valley Precision spring won me over due to its attractive price point and the positive reviews highlighting its effectiveness in taming PCC recoil.
My initial reaction was one of cautious optimism. While I was excited to see if it would deliver on its promises, I also knew that simply dropping in a stiffer spring wasn’t always a guaranteed fix. The true test would come at the range.
Real-World Testing: Putting Kaw Valley Precision Extra Power 17-4 SS Pistol Caliber Carbine Recoil Spring to the Test
First Use Experience
My first outing with the Kaw Valley Precision Extra Power 17-4 SS Pistol Caliber Carbine Recoil Spring was at my local outdoor range. I primarily tested it with my 10mm AR PCC, feeding it a mix of 180gr and 200gr full metal jacket ammunition. The weather was clear and sunny, offering ideal shooting conditions.
The difference was immediately noticeable. With the new spring installed, the felt recoil was significantly reduced, and the bolt cycled much smoother. The “snappy” feeling I had previously experienced was gone, replaced by a more controlled and predictable recoil impulse. The extra pre-load of the spring definitely helped keep the bolt closed for longer, reducing the blowback effect.
There was a slight adjustment period, as the increased spring pressure required a bit more effort to charge the weapon initially. However, this was a minor inconvenience compared to the improved performance. I didn’t experience any malfunctions during the first range session, which was a promising sign.
Extended Use & Reliability
After several months and hundreds of rounds, the Kaw Valley Precision Extra Power 17-4 SS Pistol Caliber Carbine Recoil Spring continues to perform admirably. There are no signs of significant wear or fatigue, and the spring tension remains consistent. The 17-4 stainless steel construction appears to be holding up well against the constant cycling and stress of a blowback system.
Maintenance is simple; a quick wipe down with a lightly oiled cloth after each range session is all that’s required. The stainless steel finish makes it easy to clean and prevents corrosion. I haven’t experienced any issues with rust or pitting, even after shooting in slightly damp conditions.
Compared to my previous experience with a standard carbine spring, the Kaw Valley Precision spring is a clear winner. It significantly improved the shooting experience of my 10mm AR PCC and has demonstrably reduced the wear and tear on the internal components. It has exceeded my expectations, providing a simple and cost-effective solution to a common PCC problem.
Breaking Down the Features of Kaw Valley Precision Extra Power 17-4 SS Pistol Caliber Carbine Recoil Spring
Specifications
The Kaw Valley Precision Extra Power 17-4 SS Pistol Caliber Carbine Recoil Spring is designed specifically for pistol caliber carbines utilizing the AR-15 platform. It’s constructed from high-quality 17-4 stainless steel, which offers excellent corrosion resistance and durability. The spring is designed to be compatible with carbine-length buffer tubes and is suitable for 9mm, .40 S&W, .45 ACP, and 10mm calibers.
The key specification is its extra power design, which provides increased pre-load compared to standard carbine springs. This increased pre-load helps to keep the bolt closed for a longer duration during the firing cycle, which is particularly important for blowback operated systems. This translates to reduced felt recoil, quieter operation (especially with a suppressor), and decreased wear on internal parts. The 17-4 stainless steel material ensures longevity and resistance to corrosion in various environmental conditions.
Performance & Functionality
The Kaw Valley Precision Extra Power 17-4 SS Pistol Caliber Carbine Recoil Spring excels at its primary function: taming the recoil and improving the cycling of pistol caliber AR-15s. It effectively reduces felt recoil, making the firearm more comfortable to shoot, especially during extended range sessions. By increasing the dwell time, it ensures more consistent and reliable cycling, reducing the risk of malfunctions.
Its strength lies in its simplicity and effectiveness. It’s a drop-in replacement that requires no modification to the firearm, making it easy to install for even novice users. The only potential drawback is the slightly increased effort required to initially charge the weapon due to the increased spring pressure. However, this is a minor trade-off for the overall improvement in performance. It absolutely meets, and arguably exceeds, expectations considering its simple design and affordable price.
Design & Ergonomics
The Kaw Valley Precision Extra Power 17-4 SS Pistol Caliber Carbine Recoil Spring boasts a simple yet effective design. The 17-4 stainless steel construction ensures durability and corrosion resistance. The spring’s weight is negligible, so it does not noticeably impact the overall balance or handling of the firearm.
It is a user-friendly component, with no learning curve involved. It is a drop-in replacement, easily installed by anyone familiar with basic AR-15 disassembly procedures.
Durability & Maintenance
The 17-4 stainless steel construction suggests this spring will last for a very long time. My months of usage haven’t shown any notable degradation.
Maintenance is straightforward. Regular cleaning and light lubrication are all that’s needed to keep the spring in optimal condition.
Accessories and Customization Options
The Kaw Valley Precision Extra Power 17-4 SS Pistol Caliber Carbine Recoil Spring is a standalone component and doesn’t require any specific accessories to function. However, it is often used in conjunction with other upgrades to optimize PCC performance. A heavier buffer is a common pairing, as it further increases the reciprocating mass and helps to smooth out the recoil impulse.
While it’s compatible with any standard carbine buffer, pairing it with a Kaw Valley Precision heavy buffer, or a similar product from another reputable manufacturer like Angstadt Arms or Blitzkrieg Components, is highly recommended. It’s also compatible with various aftermarket buffer tubes, stocks, and other AR-15 components.
