Ratings & Reviews
Necessary trigger/hammer pins accessory
by Rob K
As recommended for trigger upgrades on a S&W M&P15-22 the KNS pins provide anti-rotation and anti-walking of stock pins. The KNS pins functions perfectly as designed though I would have preferred these aftermarket pins & fasteners to not have a raised profile on receiver, but flush instead. Overall still a very good product and functional.

Factory pins rotate out under rapid fire. KNS Pins eliminate this problem. Easy install. Highly recommend.
good deal! they work well and the trigger pins definitely will not be going any where!

Good folks selling good products at good price

I was happy to find the KNS non rotate pins for my M&P 15-22 at Primary Arms. Their Website is easy to use and they were quick to ship my order!The elegantly designed KNS Non-Rotate Trigger/Hammer Pins install as easy and work great.
Just what I needed. Installed a POF drop in trigger in my 15-22 and found out the hard way that the included KNS pins didn't fit since the 15-22 lower receiver is just slightly wider than a standard AR. Ordered these pins from Primary Arms and had them at my house and installed 4 days later. Perfect fit and rifle functions perfectly.
Simple to install and works perfectly
by D. Workman
KNS solution eliminated my worry of the hammer/trigger pins loosening in the polymer lower of my M&P 15-22. KNS's design is elegantly simple in every way including their simple installation. Looks great too. I installed the pins with just a small plastic hammer to gently tap in the new pins that displace the old. I then used the supplied torx key to gently snug the screws that have thread lock pre-applied. Done!Worthy every penny.

Pick these up because my trigger pin from my 15-22 kept rolling half way out, so got some of these KNS pins and they remedied the problem. They also make my MOE 15-22 look that much sexier. Thanks Primary Arms for the deal and the quick shipping. You guys got my business for all my black rifle needs for sure.

Primary arms shipped this fast. I will be doing future business with them!
Great part and service
by Shawn Fyffe
This non-rotating pin set fits the 15-22 and solves the problem that some have of the pins walking out of their holes and parts. I haven't had any problems and now I know I won't. They took about 3 minutes to install and not much longer to get to my house after I ordered them. This was my first order from Primary Arms, but won't be my last.

This set from KNS was specific for the Smith and Wesson 15-22. It arrived quickly, and was extremely easy (5 mins) to install. Its an inexpensive, easy and great looking upgrade for the 15-22, and removes all concerns about those stock pins, which just seem too short.
KNS pins did the trick
Wanted security and peace of mind, got it wiith these pins and the service of Primary Arms.Liked them so much I went onto ebay and bought a Burris Tac30 1-4 scope with their mount from their online auctions.
Fair price and fast Shipping. Thank you!!
Perfect fit! Nice and tight no side to side slack like on my m&p 15 kns pins. As always easy install and the "dog bone" style looks pretty good. Was sceptical at first but does look cool!

Very happy with the product. Fits perfect and easy install. Love the look and the security of knowing the pins won't come out on there own now.
Best there is

These are a must have for a 15-22 if you shoot any volume. I have them on 3 guns and just ordered a 4th set for a 2nd 15-22. One set has been in a 15-22 for over 5 years with well over 50K competition rounds and never an issue. I run all hiperfire triggers and the work great with them.
