Bolt a flashlite (excuse me, tac light) to the mag tube, like guys do for a shotgun.
Folding stock is mandatory.
Picatinny rail on top with a Ecog or similar. Co-witnessed to a peep, duh.
Low-mass firing pin.
Heat shroud on the barrel.
Tactical loading port hatch.
Thread barrel for a flash suppresor.
Hard chrome the whole [bleep] thing. Or Parkerize.
Replace fore-end with a tri-rail. Hell, a quad rail. Mount a sling attachment point, laser illuminator, and........... something else to it. Oooh! One of those vertical grips.
Gotta have extra ammo somewhere for those mutant cannibal firefights. Elastic loop thingy on the folding buttstock?
