It's long been standard practice to safety-wire critical connectors and fittings on aircraft. They used safety-wire to make 100 percent certain that nothing moved. Unfortunately, this process is not possible with your gun, even if it was it would be ugly. On the plus side, you get the chance to accomplish the same thing with a set of KNS anti-rotation pins.

Why Do I Need AR-15 Anti-Rotation Pins?

In quick succession, trigger and hammer pins coming loose and "walking out" during rapid fire is a common problem when firing full-auto AR-15s or firing semi-autos. If you as a AR owner is experiencing this problem, you have come to right place. The KNS Precision Generation 2, Modification 2 Non-Rotating Trigger and Hammer Pins eliminate this problem by attaching the two pins to one another with a set of exterior stainless steel retainers.

Undoubtedly, when you install a set of AR-15 anti rotation pins, you have taken the single best precaution to eliminate pin rotation and walk. Something as quick and simple to install as a little KNS hammer and trigger pin just gave you one less thing to worry about. A set of KNS AR-15 non rotating pins comes to you with a valuable, conical, brass guide. The design of this guide makes installing your KNS anti-rotation pins easy because it keeps tension on the trigger group during the switch.

KNS Hammer And Trigger Pin Are Easy To Install

Is installing a set of AR-15 anti rotation pins something you really should consider? Well, that depends on several things. Quite a number of things can cause your pins to walk out on you. Automatic fire, an improperly tuned gun, excessive recoil, and some receivers have holes that are a bit out of tolerance to begin with. Ultimately, if you shoot enough the pins will move. The answer is a KNS hammer and trigger pin set, it puts a stop to all pin movement. Stop rotation, stop pin walk, stop receiver wear, install KNS AR-15 non rotating pins. This mod will not interfere with operation of your AR-15's exterior controls in any way. In fact, the installation can be performed without any permanent modifications or gunsmithing knowledge!

  • A must!

    Posted by -Edgar on 17th Feb 2017

    I'm always working on the triggers on my rifles and this part is recommended, if you don't want your factory pins to walk out. If you like me and shoot around 600 round per weekend, its a must. Plus they look good on FDE!

    Dropped a 1 piece trigger in my daughter's AR Pistol, these red anti-rotation pins just add to the red. It is wicked.

  • easier than I thought

    Super easy to put in, I really like the brass button that helped punch out the older pins without losing tension. The green looks great.

  • Good Investment for Polymer Lowers

    Posted by John on 3rd Oct 2016

    I bought this to use in a polymer lower since the material is significantly softer than the usual aluminum (for you English types, please note there is only ONE letter 'i' in aluminum). Assembly was simple and quick, even with the very tight tolerances in my lower. I went with black, but pick the right accent color for your needs and sleep well knowing your trigger and hammer pins are stable!
