You have standard (.154") hammer and trigger pins

Anytime

The ARs with the larger hammer and trigger pins were Colts. For many years Colt semiautos shipped with .170" hammer and trigger pins. They transitioned back to standard .154" pins a year or two ago. It was sometimes a pain in the ass trying to find an aftermarket trigger for a large pin Colt. Since I have ARs in both sizes I stock both sizes of trigger parts, so it wasn't a big deal for me.

Don't mean to hijack the thread, but I thought this would be a good opportunity to ask. Do the new Colts wih the smaller pins still have that damn trigger block or not?

Colt has not used a pinned in place sear block in a long time.  The lower receiver will be webbed to prevent the use of an DIAS, though.  This in no way affect the bolt carrier or any aftermarket triggers like the sear blocks did.

The only people who will be affected are the ones who have RDIAS.  That is a very small number of people overall.
