Firing Pin Protrusion Gage/Gauge - Who Sells Them?

I’m looking for a military-style gage (the one that looks like a flat strip of metal with max and min notches on each end). The only one I can find is sold by Bushmaster. Does anyone else sell these things?

Thanks.

Brownells is your friend, but they are currently out of stock. I do have one of these:

You can set them up to notify you when they are back in stock, that usually happens pretty quick.
