Colt Large pin question.

AR/M4 AR Technical Discussion

I was looking thru the brownells colt parts and they have listed a .170 and .171 pin listed. I was just wondering why the difference.

Thanks

To the best of my knowledge it’s a typo.

Hello,

Actually, .1713" Diameter Pins are available - the pin is plated.
