Sometimes you can check the hole size with a drill bit.

Or a Roll pin punch. I have one in the gas port now keeping things aligned, if not totally fastened, while I order more pins.

I've done that, and I have a 115 piece drill bit set. But if it's slightly loose the next size up won't fit, and if it's slightly too tight then then the next size down will be way too loose.

Unless it fits perfectly, it just gets you a ballpark.

I had problems replacing a firing pin on a revolver. The firing pin shaft was 1/4" exactly, but the hole was too tight for it to go in and I couldn't figure out what was going on. The drill bits didn't help and I had to take it to a gunsmith and let him deal with it. Turns out the hole was peened ever so slightly making it just barely smaller than the firing pin shaft. I mean it was sooooooo close but the firing pin just would not go in.
