True... however, I wouldn't want a 30 round mag for that ROF. I'm doing the M16 mag mods, yet getting 120-round midcaps, probably. Or, if I get a raise or so, perhaps even an electric auto-winding 1000 round drum mag : )
I like multiple safeties, really... simple solution to the front one, just don't turn it on in the first place. Back one's always there, and it's the same mechanism as every other one. However, I'll admit changing from semi-full's a bit confusing... ah, well. Who needs Semi with that rate of fire?
