dunno if its been addressed already, but i would like to see a proper Dao-12 hit the market. maybe more than just the regular 3 barreled shotguns as well, be cheaper than the CAW revolving nade puncher, but more of a spray than the regular spaz 12 or m3
pretty simple too, loads like a revolver, shoots like a shotgun.
shells would have to be gas, like a smaller version of the regular 40mm
could have a variety of different shells too, 8mm, dummy (just cram junk into it and fire, baby powder is nice for this).
