Corrosive .223?

Its been a couple weeks but surprising for ammo sold as non corrosive. The tavor has all sorts of interesting and hard to reach nooks and crannies and certainly not a rifle I want to run corrosive thru.

I tried to get a better quality pic but the camera was being uncooperative.
 
I don't think Tula is or has been corrosive but with all off shore ammo it is always a possibility. Years ago back as far as the 80's there were a few imports of ammo from South Africa, China, the Philippines with corrosive primers but it was the odd time to encounter it. Odds are today that you are not going to encounter any. I just cleaned my Tavor for the first time since I bought it last winter. Didn't see any corrosion but I will be more vigilant about cleaning after seeing your pic.

Get the lot number of the stuff if you can. It'll help everyone to cross check theirs
 
I had the exact same thing happened as original poster. I figured it wasn't the ammo though From new the gun has a coat of some kind of anti-corrosion and when the gas burns it off it looks just like that. It went away after a few hundred rounds. The gas tube had a light blue-ish gray haze smoke on it and where those orange specs are in your pics mine had crusty blue and gray type of ash that had to be scribed off.
 
ok not a single bit of lube or oil on that part in the photo, heat can course that. if it was corrosive ammo it would look alot worse then that.
try cleanign and oiling you gun and se if it happens again
ive shot about 5 cases of this stuff and never see that issue.

I agree. Bare metal covered in carbon mixed with moisture will cause that if not cleaned/oiled. Will likely wipe away with no real evidence.
 
i have a crate of the "CJ95" 2 x spam cans from norinco and shot maybe 100-200 rounds thru a CQA.
I cleaned the CQA right after(it sports a "yankee hill" flash suppressor).
2 weeks later i checked the gun out and there was a lot of green "oil" in the chamber(i oil liberally)
the flash suppressor was rusty and i had to scrub it and oil like crazy.

i believe the norinco spam can stuff is mildly corrosive.
 
Norinco spam can CJ95 isnt corrosive...

I've got an AR that shot more than a thousand between mid june and mid july and has been sitting in its case. Just cleaned it tonight (5 aug 16) no rust at all.

Dirty but not corrosive
 
Never used the 62gre Tula but I used lots of the 55gr and didn't find any sign of it being corrosive. And it's not like I clean my AR's after every range outing, far from it. Can't see them switching the primer for the 2, so I would say you have other issues.

Tavor piston isnt supposed to be oiled. My safe has dessicants inside, all other guns are fine. Did not wipe away with "no evidence" the rust has begun pitting into the piston and needed an abrasive to work off. I work with steel for a living and I know surface rust when I see it. It's the same corrosion that covered the piston on my old sks, that fuzzy looking ####.
 
Just because the ammo is non corrosive doesn't mean steel will magically not rust.

Steel.. Moisture in air... Rust...

A clean rifle can rust too if it's not oiled, is the cleaning product corrosive then?

Edit: as an additional note I shot ~300 rounds of 62gr Tula through my one T97 and didn't clean... Zero issues at all.
