"redundant recoil controls" would mean several recoil systems that do similar things, so that you either get more of an effect from it or are covered in case one fails.
And the antipersonnel bit ain't too redundant in any case. You think guns are always gonna be the size they are now, or that you'll get a bit more effect, pound-for-pound, in a couple centuries. I've got a disposable grenade launcher somewhere that's half the size of this thing.
Venom: No, that's where you put your other hand. Thing must weigh 20+ pounds at least, you couldn't treat it like a pistol for too long- particularly if you're actually using it.
