KNS Precision The Discarder Review

First Impressions of KNS Precision The Discarder

The KNS Precision The Discarder promises a smoother, more controlled shooting experience for FN SCAR owners. As someone with over a decade of experience in tactical gear and weapons platforms, I’ve seen countless aftermarket modifications promising similar results. What sets this apart is its tool-less adjustability and focus on mitigating the SCAR’s notoriously aggressive recoil impulse. I was eager to see if this little device could truly tame the beast.

I needed to solve the problem of over-gassing on my suppressed SCAR 17 SBR. I was looking for a way to reduce felt recoil and internal wear. The promise of extending the lifespan of my rifle was definitely appealing.

My first impression upon unboxing the KNS Precision The Discarder was that it was a well-machined piece of kit. The nitride and nickel boron finish looked durable and ready for hard use. Its compact size was also a pleasant surprise, reinforcing the claim of suppressed use compatibility even with short barrels.

I considered the PMM (Parker Mountain Machine) SCAR Gas Control Screw. I also looked at purchasing additional OEM FN gas jets in various sizes. I ultimately chose The Discarder because of its adjustability and the claim of tool-less operation once installed.

I was cautiously optimistic. I’ve used other adjustable gas systems with varying degrees of success. The KNS Precision The Discarder had the potential to be a game-changer, or just another paperweight.

Real-World Testing: Putting KNS Precision The Discarder to the Test

First Use Experience

I tested the KNS Precision The Discarder at my local outdoor range, utilizing both suppressed and unsuppressed configurations with my SCAR 17 SBR. The initial conditions were dry with a slight breeze. This allowed for a good baseline to assess the impact of the device on recoil and muzzle rise.

The installation was straightforward, and the tool-less adjustment worked as advertised. Even with a full-length rail, the front sight post provided enough clearance to make on-the-fly adjustments. After a few magazines, I could noticeably feel the difference in the recoil impulse, especially when suppressed. It was softer, more manageable, and less violent.

The most immediate issue was finding the optimal setting. With too little gas, the rifle wouldn’t cycle reliably. Too much, and I was back to the original problem.

Extended Use & Reliability

After several range trips spanning multiple weeks and hundreds of rounds, the KNS Precision The Discarder has proven its worth. There are no visible signs of wear and tear on the device itself. The finish has held up exceptionally well.

Cleaning is as simple as wiping it down with a cloth and applying a light coat of oil. It is much easier than trying to remove and clean individual gas jets. The adjustment detents remain crisp and tactile, holding their position even during rapid fire.

Compared to using stock gas jets, the KNS Precision The Discarder offers a dramatically improved shooting experience, especially when suppressed. The recoil reduction translates to faster follow-up shots and greater overall control. I am now able to keep the red dot optic on my target even during rapid fire.
