R-15 trigger pin diameter

.204

New member
I'm @ work and trying to order a trigger off the net and my [beeep] digital micrometer battery is dead. I was wondering what the pin diameter is on the R-15. .154" or .170"? I have another micrometer @ home and could do it after work but that would cut into my yote calling this evening.

almost all ARs except early colts are small pin, the early colts experimented with large pin. I don't know the exact diameter, just large and small. R-15's are small pin.
 
That is correct, you need the .154 pins. Only Colt uses the .170 pins and most current Colts also use the .154 pins (as well as many of the older Colts), when working with Colts it is best to measure them.
