KNS Precision Hammer and Trigger Pin Mod. 2 Non Rotating .154 Inch

Great product...put it on a RRA 2 stage match trigger. and aero lower. Would definitely buy again and there's no going wrong with primary arms.

Great products and great service from PA

Great quality - use these in all my builds. Especially if you go full-auto or use the Slide Fire stocks.

Great service, fast shipping, and an incredible deal. I use these on all my builds. They look really cool on the lowers and gives that secure feeling.

Hammer & trigger pins were easy to install. Looks good. I will be buying a second kit for my other rifle.

Have not installed yet, waiting for trigger kit first. found great price in this site and now I'm a loyal Customer,

Have these pins on all of my AR's with the exception of the last two builds. Now that they are all installed I am confident of no problems.

HIGHLY RECOMEND PRIMARY ARMS... SUPER FAST SHIPPING ,SAME DAY.... EXCELLENT SERVICE ... HAD A QUESTION ON MY ORDER AND RESPONDED BACK IN MINUTES... THANK YOU PRIMARY ARMS FOR YOUR SERVICE....

Honestly, I bought this for the looks & it was on sale

I always make sure to install these on every AR that I build. If you run these on a softer billet lower, like a 6061 home-build or billet lower, these anti-rotate pins will help keep your lower running fine forever. No worn out hammer/trigger pin holes, and no accidental double fires from oval'd out holes.Also, another thing that makes these so valuable is that it gives your trigger finger a perfect place to hold on to when you running & gunning. That way if you slip or fall or something, there is a positive thing to grip with your trigger finger that will help prevent accidental discharges. For that reason alone, every AR should have these.
