Let’s Talk About KNS Precision Safety Detent
The KNS Precision Safety Detent is a small but critical component in the AR-15 platform, responsible for providing the tactile feedback and positive engagement of the safety selector. Manufactured by KNS Precision, a company known for its innovative firearm components, this detent promises enhanced durability and a more refined feel compared to mil-spec alternatives. For a price of around $1.70, it seems like an inexpensive upgrade, but the user reviews suggest a potential gamble regarding quality consistency, making a thorough review essential.
My interest in the KNS Precision Safety Detent stemmed from a persistent issue with the mushy, less-than-positive safety selector engagement on one of my AR builds. I was aiming for a crisp, decisive click with each safety position, and I hoped this part would be the simple, affordable solution. I had initially considered complete safety selector kits from other manufacturers, but the low cost of the KNS Precision Safety Detent made it an attractive first step in troubleshooting.
Upon receiving the KNS Precision Safety Detent, my initial impression was somewhat neutral. It looked like a standard detent, but the Black Nitride Finish gave it a sleek, professional appearance. The weight and feel suggested solid construction, but without close inspection, it was difficult to assess the machining quality described in some of the user reviews. I am familiar with other detents on the market, like those included in Radian Weapons Talon ambidextrous safety selectors, and while those complete kits are undoubtedly high quality, their premium price point made the KNS Precision Safety Detent a more appealing initial upgrade attempt.
First impressions left me cautiously optimistic. I was excited by the promise of improved safety selector engagement, but aware of the potential for inconsistent machining. This inexpensive part held the promise to be the solution I was looking for, or would become a cautionary tale about cutting corners on essential AR-15 components.
Real-World Testing: Putting KNS Precision Safety Detent to the Test
First Use Experience
I tested the KNS Precision Safety Detent at my local shooting range, replacing the original detent in my AR-15 lower receiver. The weather was dry and mild, making for comfortable conditions to assess the part’s impact on safety selector function. Installation was straightforward, requiring only a punch and a few minutes of time.
Immediately, I noticed a difference in the feel of the safety selector. The engagement was noticeably firmer, with a more pronounced “click” as the selector moved between safe, semi, and (though this is a civilian gun) the imagined full-auto position. This immediate improvement was encouraging.
No issues arose during the first range session. The safety selector operated smoothly throughout, providing consistent, positive engagement. I dry-fired the weapon multiple times, paying attention to how the safety selector felt, and it continued to impress, as opposed to the softer, mushier feeling of the factory detent.
Extended Use & Reliability
After several months of use and approximately 1000 rounds fired, the KNS Precision Safety Detent continues to perform well. There are no signs of wear and tear, and the Black Nitride Finish has held up admirably, showing no signs of rust or corrosion. The improved safety selector engagement remains consistent, providing a noticeable upgrade over the original mil-spec detent.
Maintenance is virtually nonexistent. I’ve cleaned the lower receiver several times during the testing period, and the KNS Precision Safety Detent requires no special attention beyond a quick wipe down with a lightly oiled cloth. It is as low maintenance as a simple part such as this can get.
Compared to my previous experience with the mushy mil-spec detent, the KNS Precision Safety Detent is a clear winner. The improved tactile feedback and positive engagement inspire confidence in the weapon’s safety, and the peace of mind gained from this is substantial. The change is small, but makes a huge difference in the perceived quality of the rifle.
