Mine has had a steady diet of German surplus 7.62 NATO date coded from 1959 up to the late 80's. Some of it even the slightly tarnished bulk stuff. In the 80's the surplus German stuff was cheaper than even 5.56, and we shot tons of the the stuff.
I will say that my experience you should not run the HK "wet" like an AR. It's not needed, and appears to trap & suspend more carbon that would normally get blown out with ejection. So light lube for the critical areas is what I've found works best.
I'm going to have to disagree.
I carried one for 7 years, and the weapon gets dirty as hell in my opinion. We always kept the rifles well lubed, both internally and externally. My experience with DI AR's is limited, but I helped shoot 1000 rounds through a C8 SFW in a few hours once. It was pretty dirty, but 1000 rounds through a G3 would be hell.....especially the barrel extension/trunnion area, as well as the chamber and barrel.
It the weapon was not lubed, the fouling would harden and build up quite rapidly. We found a very good technique for cleaning the extension, by using a plastic cleaning rod meant for the cocking lever housing and what is best described as cleaning yarn:
It's not about surviving, it's about winning!
