wwillson Posted June 17, 2011 Report Share Posted June 17, 2011 I got back from shooting PD's three weeks ago and put my ARs back in the safe. I got them out last weekend to clean and found green corrosion on the back of the bolt of my brand new Bushmaster! It wasn't too bad yet, but nonetheless, it was there. What in the powder/primer leaves a residue that's corrosive? I'm I misguided in believing that smokeless powder rifles don't need to be cleaned immediately after use?Thanks,Wayne Quote Link to comment Share on other sites More sharing options...
BarryinIN Posted June 17, 2011 Report Share Posted June 17, 2011 Being green in color, my first thought is that it's from copper fouling being sent down the gas tube to the bolt tail, where it reacts with any ammonia from solvent remaining there. Perhaps something in your oil eats on copper also.I have seen bolt tails kind of copper-washed, so it does get there. Quote Link to comment Share on other sites More sharing options...
wwillson Posted June 17, 2011 Author Report Share Posted June 17, 2011 Barry,This AR was brand spanking new, so I'd never cleaned it, just looked it over to make sure there were no obstructions etc.Wayne Quote Link to comment Share on other sites More sharing options...
BarryinIN Posted June 17, 2011 Report Share Posted June 17, 2011 I wonder what lube/cleaner they use at the factory that would have been left in there then. Quote Link to comment Share on other sites More sharing options...
FNFAL308 Posted June 27, 2011 Report Share Posted June 27, 2011 I would be interested in what type of ammo you were shooting, might it have been WOLF?The ammo may not have been corrosive per se as I have noted some greenish grud on the gas piston of my FAL's after shooting S/A Ball for example. In your case it may have just been some dirty stuff.. If there was no rust noted I'd say your GTG.. Clean, lube and put it back in the safe.. Modern ammo loaded (or hand-loaded) with smokeless powders do not need to be cleaned right away.. Even living in FL I usually don't clean anything right away "except" guns fired with corrosive ammo.. These are usually Bolt Gun, although I do fire some corrosive ammo in my AK's, and some other auto loaders. If I plan on shooting a specific rifle/s in the next couple weeks I just wipe it down good and put it away.. Once I'm done with that particular piece fora bit it gets thoroughly cleaned and lubed than put away.. Quote Link to comment Share on other sites More sharing options...
wwillson Posted June 27, 2011 Author Report Share Posted June 27, 2011 These were my handloads with CCI primers and Hodgdon H-335. Certainly nothing corrosive with those loads. I'm still a bit perplexed.Wayne Quote Link to comment Share on other sites More sharing options...
FNFAL308 Posted June 27, 2011 Report Share Posted June 27, 2011 Nope that load is GTG all day long..Prolly nuthin at all, as mentioned I've gotten green stuff on the Pistons before.. Clean it off and apply a touch of lube.. Quote Link to comment Share on other sites More sharing options...
