Roll Pin Sizing

[Minfred]

Other than length is there a difference between the AR bolt catch release roll pin and the CZ 75B front sight roll pin?

[gunzip]

A used CZ 75B front sight roll pin in my collection is 0.080" in diameter.

Wouldn't a CZ roll pin be metric and AR pin SAE?

Wouldn't a CZ roll pin be metric and AR pin SAE?

Exactly. That 0.080 inch roll pin is much more likely a 2mm roll pin.

American roll pins are much more likely to be fractional inch size (e.g. 1/16", 3/32", 1/8") than decimal. That 0.080" does not convert to a convenient fractional size.

How long is that used front sight roll pin?

How long is that used front sight roll pin?

The front sight roll pin on all CZ 75s is 2mm dia. x 10mm long. Is that what you're asking?

Yes, thank you.
