Hello all -
I was at the range the other day and a man was disassembling his ar15. I noticed that he had a different cotter pin than what I had in my colt. I've looked it up, and its a KNS Perma pin? that is claimed to be the "original".
Anyone have info on this? The gentleman also claimed that this version of the cotter pin was of a higher quality. I've only ever bent one cotter pin, and took all of two seconds to find a replacement.Why is this supposedly better?
