I have these M1 Gas Cylinders . . . .
I bought a lot of them from Century when they were closing them out, and 4 of them are sandblasted on the outside, and unfortunately on the inside too. Should I even bother to find someone with a gauge to check them?

The GI gage reject is a very small ware limit as the military had lots of cylinders and the rifles were being returned to possiable combat. For us not so fortunate and demanding I have found cylinders as large as .531 work just fine with a new oprod piston. I use Smith Ent .528 oprod pistons with the worn cylinders. Don't throw any away, sand blasting probably didn't hurt them, clean them up and measure with a plug gage. You can make your own gage out of magnum rifle cases and using a micrometer. Several years ago I posted a "HowTo" on Culver Tips, if that's still around. Ivan

Ivan, I remember that "How To", and thank you for sharing; makes for a great, cheap gunshow gauge.

Some Gas Cylinders "Slip" on, some are "Pushed" on, some are "Tapped" on, and some are "Driven" on. I like it when you must drive it on with brass and a big hammer.
