I'm an italian shooter,gun collector...and AR15 rifle enthusiast!
I recently got a RRA 2-stage NM trigger group that I'm planning to use in one of my AR type guns,specifically an Oberland OA-15
The instruction sheet that comes with the trigger stresses the use of the pins provided with the kit,but I own a set of KNS non-rotating pins and I would like to try them
Could I have functioning problems if I use this combination?Thanks for advice.

I would check both sets of pins with a micrometer and if they are the same diameter you should be fine with the KNS pins. The RRA pins are just pretty precise in diameter to eliminate extra movement.

I would recommend the .1555 KNS pins with the RRA 2-stage. I have seen the standard .154 pins work, but it seems to be hit and miss, depending on the lower.

I have the .155 pins installed on my new build with an RRA NM 2-stage...

It is tighter than a 12................

You get the point, it's awesome.
