OK, I am thinking about buying the Timney Drop In Trigger Kit for my Armalite AR-15. My question is, do I need the small or large pin kit? Can anyone help, I am in Afghanistan so I wont be able to install the kit untill I get home but I am going to oreder one in the next few days? Thanks R
So far as I know, Colt is the only company that currently uses the "large pin" version but I'm not 100% positive of that. If your Armalite is a newer gun, I would bet that the "small pin" is correct, if your Armalite is more than 3 or 4 years old then I would be in doubt.
EDIT, double checked, the current production Armalite is a small pin version.
