I’ve got little discrepancy with real model of this shotgun. Photo
First: In game this shotgun accept stock replacement. But this is bullpup shotgun.
Two: In game this gun have occupied “underbarrel” slot. Real model is have underbarrel rail.
Third: Maybe, move builtin mod to “magazine” section, that make free “underbarrel” slot for front grip(also popular mod for real shotgun)?
Excuse me for bad translation.
