KNS Precision Non-Rotating Pins AR-15 .154" - Black

Worth their weight in gold. I got them on sale for 25$. They are better than milspec they make the rifle more durable and reliable. They weigh nothing. They are made in usa. They look good. They are easier to install than stock. There is no cons to having these pins besides they stick out each side 2mm like they are supposed to. This is not a fad it is a real improvement on the original design all Eugene stoner rifles should have these they are one of the cheapest nest bang for your buck upgrades out there for the m16. KNS stands behind their products. What more can I say buy them you will like then.

Works great...no more sloppy trigger! Works so good I bought two more.

Worked perfectly for my 9mm AR build. A+

Worked great with Timney trigger, easy installation, great service and best price anywhere. Will shop with PA again.

While the KNS pins may not be a function requirement for the average semi auto. It gives the lower receiver the finished high quality look.

While I was somewhat skeptical as to the practicality and functionality of these pins, I am now a firm believer. I installed these on two new builds using DTI lowers and Stag LPK's. While everything was already exceptionally tight and the appropriate trigger components had been polished there was still the ever present slight creep in the trigger pull. Even though KNS doesn't tout these pins as helping with trigger creep, they do. Once they were installed the slight play that was present in the trigger group completely disappeared. These are definitely worth the money and I like the added assurance that there will be no receiver wear around the pins in the distant future. These KNS pins will become a standard component on all of my future builds.

when you have a trigger and or a hammer pin walking on you, you need this. it take care of the pin walking out on you. and with the stainless steel pins the trigger feels slightly softer.

What else can be said about KNS products? They are totally professional in their manufacturing and the fit of these antirotation pin set is perfect!This as also perfect as the Customer Service at Primary Arms!The Good Guys to deal with in Texas, of course!

Very well made and finished.Do wish that KNS would include a spare screw just to have on hand.

Very fast order turnaround, and everything as expected. I'll be using these chaps a lot more now.
