gas plug rust

[rascal1]

This is interesting. Every time I pull my gas plug I have been greasing the plug threads. To date, I haven't encountered any problems. Mind you I don't shoot tons of ammo through it either. Maybe 200-300 rounds per year. A 2007 import, purchased new in 2008.

1000 rds through mine with never seize on the gas plug threads. No issues and ensures that you can get it off again if it has been sitting for a while.

That's the other thing. If you don't use something on the threads, it tends to weld itself in place and is a PITA to get off.

Ah, so my answer would be, "use it LOTS" LOL!

How about - shoot it today, when you put it away, take off the gas plug and store it with your ammo???

Looks like it was assembled dry and left to sit a while. Smokeless powder is hygroscopic and h2o is a byproduct of combustion. Add ambient humidity and heat in proximity to iron and you get iron III oxide aka rust. I've bought two rifles from CGNers that never saw corrosive ammo but were shot and left uncleaned for months. Both have minor pitting in the bores. I always clean powder fouling and oil steel surfaces after shooting. Corrosive cleaning gets the copper removed too.

Neither smokeless powder or its residues are hygroscopic in any way. I don't clean guns unless they have been shot enough to need it, and some of them have had fouled bores for over a decade, there is no sign of any kind of pitting or corrosion. In fact I have seen guns that showed signs of corrosion everywhere except where surfaces were covered with firing residues: the soot deposits appear to have protected the steel, possibly by soaking up oil and holding it close to the metal.

And rust is not simple iron(III) oxide. It is complex mix of iron oxides and hydroxides, mostly hydrated, with the specific proportions varying depending on oxygen availability at any given point.

Maybe cleaned properly, but put back together with moisture still in the threaded area?
