I have a d35382 3 sa op rod for a M1 rife and it appears to be made of stainless steel. There is a black spray painted finish on it and wherever the finish is
worn the metal is super bright. It will not take cold blue at all. Dis they make any all stainless steel op rods? Just curious.

I talked to John Lawson who worked on these in the Army and he said no such Army animal. It may be an after market one.

Never saw one that was stainless. Most of them that I've come across were regular ordnance-type steel that was parkerized

The gas cylinder is stainless, as is the piston on the end of the OP-rod; the rest is alloy steel. Oh, and a I think the poppet valve in the gas cylinder lock
screw may also be stainless. Don't be a wise guy and ask me what alloy ....

Sure enough, stumbled across a good article on Wikipedia on the matter:
The Garand was one of the first self-loading rifles to use stainless steel for its gas cylinder, in an effort to prevent corrosion. As the stainless metal could not be parkerized, these gas cylinders were given a stove-blackening that frequently wore off in use. Unless the cylinder could be quickly repainted, the resultant gleaming muzzle often made the Garand and its user more visible to the enemy in combat.That's really interesting, they always looked parked like the rest of the parts on the gun, that explains it. It would make sense considering they were designing the gun around corrosive primers and field use. Corrosive ammo and a gas-op system can be a PITA if the maintence is spotty. |

The original finish for the gas cylinder was some sort of paint coating that required curing in an oven. A good expedient today is to spray it with high temp
flat black paint that is marketed for wood stoves and BBQ grills.

Gunkote makes a high-temp bake-on coating, I wonder how that would do on a piston
