Well, after a bunch of tweaking, switching parts, and after drilling the gas port out a little, finally have my ORF Imbel working exactly like I want it to. I even have it zeroed almost perfectly. Despite my early misgivings, I am growing kind of fond of it. It is more controllable than my AK, even during rapid fire. It is also now just about equally reliable (no malfunctions in the last 500 rounds or so) and way more accurate.
The only problem I have left with it is that it is a magnet for rust. Every time I take it apart I find rust in the gas block and gas tube. I cleaned it yesterday and the entire gas system was crusted in fragile, speckled surface rust that was working at getting a foothold. The gas regulator was rusted fast eventhough I just moved it when I adjusted the gas to work with SA surplus last weekend.
It wasn't a big deal to clean and it didn't cause any damage, but still...
This seems to happen every time.
I have shot mostly Portugese and SA surplus, but also a little British and Austrailian stuff, as well as some handloads.
Should I just go ahead and assume that ALL foreign ammo is corrosive? Could that be my problem? This stuff doesn't look like the red wheatfield looking rust that I have seen result from corrosive ammo before, but I guess it could be.
The gun is parkerized. Is that kind of finish less resistant to rust?
Can anyone help me out with this?
