Looking at picking up a trigger.  It says it for "small pin .154".  Is this, or is it not, the size for standard lowers?  Looking at putting this in a Spike's lower.  


Thanks for the help.

Small pin is for standard lowers.  The only ones that used large pin are some older colts. You will be fine with small pin in your spikes. You won't be disappointed with your new Geissele trigger

^ what he said. Spikes will use small pin fire control groups (0.154), only some colt receivers will use large pin trigger groups.
