I been wanting a better tigger for my AR's for a while now. So I thought what the heck. Bought a RRA 2 stage trigger group from ADCO and a set of .154 KNS pins from Denny's Guns. Got the trigger group today and the instructions say I should use the .156 pins that came with the trigger. Will the KNS pins work?

I did some searching before buying the pins and every thing I read said that unless the receiver pin holes are warbled out the .154 pin size is the correct size to use. If I do have to use the RRA pins how are they going to fit in a .154 hole? Aren't they going to stretch out the hole to were .154 pins won't work anymore?

thanks for any and all help.

I have been told by Denny's Guns that the KNS pin size for the RRA triggers are the .1555 size.
These are the anti- spin pins ? Just so we are talking about the same product. But his answer was assuming the fact that we were using a RRA Lower.

Got two RRA USP lowers (from Pete). Both are set-up with RRA NM 2 Stage Triggers (1. came w/RRA M4 Entry Tactical complete carbine; 2. here on the EE) and .154 KNS Pins (from Teknic). They run great (MK12 MOD0 Clone & RECON). YMMV.

guam50, thanks for the reply. It won't hurt to try out the KNS pins. If they don't work then I'll use 'em with a stock trigger on one of my other AR's.

it'll work fine the bigger pins would keep the trigger's slop to a minimal though

I'm using the KNS .1555 pins(From Denny's) in my RRA 2-stage NM Lower. They were a perfect fit.
