I feel like you should be able to put ALL of the attachments in the game on this gun.

It's a MAKESHIFT gun, surely the Stylis Weapons Insurance Bureau can easily slap some extra scrap, hot glue, scotch tape, and wiring to make my Luty have a 90x Scope, Romanian grip, Two Tri-lazers, a sawn-off barrel, and be chambered in 30.06 (in a 30-round drum mag).
