re: #85 Dark_Falcon
They aren’t military grade is the thing. Military weapons based on the AR-15 platform are full-automatic or three-round burst. As for large caliber rifles, they just aren’t used by criminals. Normal pump-action shotguns are far more likely to be cut down and turned into a crime gun that a Barrett .50 cal.
They’re also weapons that could just as easily be substituted by bolt or lever-action rifles of similar caliber.
