Indeed. an AK shorty, firing 75-round drums, one after another, till the handguards charred, then smoked, and finally fell off. I was there. It took 11 of the 75-round drums, as I recall, 800-plus rounds. And it was still working just fine, though a little difficult to hold. Film at Eleven!
I've an Australian pal whose service goes back to the days of the Australian L1A1 rifle and F1 *Lawndart* who generally likes the F88, though his real cherished toy is the F89 Minimi. But he tells me the early ones indeed had their problems, worsened after they'd been affected by cleaning solvents, so don't assume all the horror stories were BS- most any weapon requires a shakedown period for the troops to become accustomed to it, but that's a fair simulation of some of the abuse they'll receive during extended combat where maintenance may be spotty, at best. I can recall keeping my own CAR15 going with oil dripped off an M35A1 truck's dipstick during a busy time or two, but it kept going for me, mostly.

*Sigh*
I want an M35A1 truck. :(
