[ARCHIVED THREAD] - trigger pin size?

Posted: 8/30/2006 9:44:18 AM EDT

Sorry all, I'm absolute newb to the black rifle. I searched and couldn't find the answer.

How does one determine whether their lower requires the small pin or large pin for the trigger?

Thanks.

Only Colts have the ~~smaller~~ LARGER trigger pins - ~~0.155"~~ 0.170"

The rest have ~~larger~~ SMALLER trigger pins - ~~0.170"~~ 0.155"

The trigger and hammer pins are identical/interchangable.

They look like this.. www.gunaccessories.com/AR15-M16Parts/TP-KNS1.jpg

Hey Mike, I just read something from Midway. It says:

Customers with older Colt rifles, or rifles from Bushmaster, DPMS, or almost any other source have a hammer and sear pin diameter of .154" and should purchase "small pin" parts.

Current production Colt rifles, have a pin diameter of .169" - .170".

Customers with current production Colt rifles should purchase "Large Pin" parts.

So that is opposite of what you said?

Mil spec pin size is .154" (small pin)
Includes most lowers, past and present, except large pin Colts.

Colt is the only manufaturer that I am aware of that uses .170" pins in new production rifles. (large pin)

I think Mr Wilson had a brain fart or something.

I recently purchased the KNS pins kit with the .154 pins and they were just a little too small in my Colt M-4 law enforcement carbine. It was purchased 3 years ago and I thought it would be mil-spec, but the pins allow everything to wiggle just a little. Do I need to get the .155 pins or go all the way up to the .170 size. I think they would be way too big for the holes. Does anyone know exactly which size is good to go? Thanks

Taking about being delexic.

The mil-spec FCG receiver hole sizes are .155, and most of the newer colt receivers are the same.

The older colts receivers had the .170 trigger pins/FCG.

, talk about being ass-backward, My apologies, I did get this wrong.

Colts have the larger pins and the rest are the smaller diameters.
