Excuse me gents, is it ok to use corrosive ammo in an AR-15 type weapon, providing it is cleaned promptly after use, or will it still gum up the gas tube?

Just received an ammo purchase and apparently I did not read the fine print.

my understanding of corrosive ammo is that it makes non CL parts rust so as long as you clean them you should be fine. I don't see how it can gum the gas tube: the corrosive part is just a chemical around the primer, when heated it deposits residues that can make non protected part rust.


hum, that's not too clear isn't it ? anyway, as long as you clean your rifle after shooting, you should be ok (Windex or other ammonia based solution help).

that's my opinion until a specialist prove me wrong

It will not hurt your weapon as long as you clean it right away , use warm soapy water first and then after drying use solvent .

Thanks gents !!

BTW what's your ammo ? Got a upper in 7.62x39 ?

Clean with hot soapy water or a thin light machine oil prior to using any bore solvent. The material in the primers is what is corrosive. It also forms a strong acid when it mixes with an ammonia based bore solvent and causes etching of chrome linings. I shoot quite a bit of it and mostly clean with break free and have never had any issues.
I know its an older subject but figured I would throw in a reply.

Necropost for me too!

The perfect solution for corrosive ammo is called 'GUNZILLA"
This stuff is magic! Before I started using it, my VZ would start rusting on the way back from the range (seriously). With Gunzilla I'm at +700 rounds and weeks since the last cleaning. I am pretty sure I'll find some rust but nothing as extreme as before with CPL or grease.

Anyway, I am not related to them in any way, but for corrosive stuff, that's my answer.
