Yeah, that big ass break on the 74s keeps it very flat and steady, combined with the higher weight compared to the AR15/M16/M4 series it is a very stable gun in full auto. The 7.62x39 guns aren't too bad though but theywere do bounce around enough that the effectiveness is only around 50 yards or so. Thats based off my limited skill and experience with full auto AKs though. With the FAL I was worried about blowing my toes off, the spread grew that large. Takes a fair bit of skill to keep a 7.62x51 rifle on target with the giggle switch engaged. But perhaps the SCAR is better in this regard? Never shot one personally.I've heard the 74s are insanely low recoil as well. I only have AKMs, so I can't really compare -- I don't think I'd even want to use full auto on an AKM due to the recoil / accuracy limitations to begin with.
But the FAL and G3 I have shot and they are downright violent in full auto, I can see why FALs were locked into semi auto fire after a while in their service.
