Use them for all triggers - RISE Armament Trigger Anti-Walk Pins AR-15

I use these things on all triggers. I used these on a Larue Tactical 2 stage trigger and Rise armament trigger. You have to have these when installing a drop in box trigger. I use purple Loctite to hold the screws in place. I have never had them walk out.I wish they kind of sent this with a tiny drop of Loctite just so that I don't have to remember to make sure I have some on me.
