Thread: Suppressors with corrosive ammo

Hi, how do today's cans hold up to 7.62x39 ammo ?
Presumably it's corrosive.

The ammo from guncity says it's non corrosive but I always clean my rifle after firing it.
Interesting point about the suppressor though. Hadn't considered it.
I have only fired about 20 rounds of that stuff so far but will definitely be keeping an eye on the suppressor.

Got to read pack, says non corrosive steel case. Meaning case is covered by lakker so won't corrode.

I've put over a case(1250 rnds) of norinco steel case steel jacket through my Howa with a dpt muzzle forward can. I had a small amount of corrosion once due to my leaving the can on for a bit. I do know better but was distracted ,white stuff growing on the first baffle, ended up as light pitting. I usually spray with crc long life and leave in the sun or hwc and it's never happened since. The ammunition is quite dirty though and I agree the labels confusing non corrosive primer or case, or both.
My experience leads me to believe it means the primer.

Ask Friwi for best advice.

Effectively, consider all ammo more or less corrosive as far as suppressors are concerned. That's why the advice is to never store the can on the rifle especially leaving it on after firing and chucking the can away. The combustion by products collecting in the can followed by the condensing/cooling gasses dragging in any outside humidity creates a perfect corrosion condition...

Should store muzzle down if leaving on.
It take off for cleaning myself and leave off.
Was asking as maybe an all alloy like dpt way to go
The sonic one has steel inserts in it so may rust out?
