"2C:39-1y."Large capacity ammunition magazine" means a box, drum, tube or other container which is capable of holding more than 15 rounds of ammunition to be fed continuously and directly therefrom into a semi-automatic firearm.
The key though, is "semi automatic". If it was a lever action or bolt action rifle, it could hold >100 rounds and still would be legal. Oh, and just to make it interesting "NJS 2C:39-1w(3) "Assault Weapon" means a semi-automatic shotgun with either a magazine capacity exceeding six rounds, a pistol grip, or a folding stock."
So, depending, the NJ magazine limit can be 6 rounds, 15 rounds, or no limit at all. You almost need a law degree to own a gun in New Jersey!
you should see Californias definitions of “assault weapons” even the district attorneys can’t agree on what is legal or not. what a joke “evil features”
So then it was the Marlin Model 60 in you image that could hold more than 15 rounds of .22 short, making the normally 14 round .22 LR rifle illegal.
Will the Marlin even cycle with .22 short?
