Geissele trigger pin walking

Why? The problem started when he added a 3rd party trigger. Why would S&W need to know or what would you expect them to do about it?

We all know the trigger hammer pins are too short for the 15-22 lower receiver. S&W saved $ on their design by using OEM AR FCG parts. The KNS pins are longer and made exclusively for the extra wide 15-22 lower receiver. My J spring was defective from the first shot. My pins started walking on the 15-22 from day one. I've been reading about how a dozen people here have had the same problem. I wonder how many people, who do not post here, have experienced walking pins. The KNS pins work and are cheaper, faster, more convenient and a better long term solution than sending your rifle back to S&W IMHO.

Three 15-22s in the family - mine and my two grandson's. None have had any problem with walking pins or broken anything. I have a single stage Jard adjustable in mine and the other two are stock FCG. Mine has 12K plus through it.

The KNS pins are a solution IF there is a problem. but I'm of the school that doesn't spend money to solve a problem I don't have.
