Easy install. fits nicely. - KNS Precision AR-15/M16 Gen 2 MOD 2 Non-Rotate Trigger/Hammer Pins

I was worried about installing these as I've never taken a trigger out on an ar-15 before and I'm not super handy. I realized that if you just get your pin started then push the new pin with the little brass bullet looking piece in behind it, you can do it without ever uninstalling the trigger. One of the pins (I guess its the hammer pin) took a little bit of finagling to get it though but it really wasn't bad just keep your finger on the hammer when your pushing the kns through. No need for a vice and all that. The pins fit my spike's tactical lower perfectly. It's nice that they give you the two star head allen wrenches to tighten it from both sides.
