Would I need a small or large pin timney trigger for a spikes stripped AR 15 lower?

Asked by: CorpDavid
Small pin. Older Colt rifles are the ONLY ones that ever used large pin.

I have a Ruger sr 762  do I need the small pin? I think it is the Colts that take the large pins. Looks like you have them in stock

Asked by: Texaspops
Correct, a Ruger would use the small pin and some Colts use a large pin.
