Thread: Corroded brass

I have had the same but worse comparing to your pics. Shot an ipsc stage at our club with the AR. It was surpressed at the time, ammo was brand new shiney hornady off the shelf stuff when it went into the mag. When i unloaded it 10mins later it was black with soot and corroded green like a battery terminal can get like. It looked like it had aged 70 years in a matter of minutes.

I measure my cleaning times with a calander so probably no solvents etc in the mix, mags were possibly the GI alloy ones if i recall rightly. Hope this helps.

Funnily enough i have never seen this happen again but ive never shot with a supressor again either.
