Bolt Shotgun

The Bolt Shotgun is one of the most cheapest and primitive weapons to 
be created, the design is so simple that you can easily make one out of 
the scrap you find in your shed.
The Bolt Shotgun is not classed as a legitimate firearm due to its 
simplicity, The Bolt Shotgun can appear in different shapes and styles 
according to the users preferences, All the weapon needs is a spring 
hammer and a barrel which you can slot a shell in similar to blunderbusses.
But Bolt Shotguns should not be underestimated, depending on the 
design structure some Bolt Shotguns can fire very high caliber shells 
which can cause devastating damage to vehicles and personal however use
 of high caliber shells can lead to the shotgun breaking.
Bolt Shotguns are not very accurate as they tend to lack barrel support and sights.
The most advanced Bolt Shotguns to be made had a drop down magazine 
so when the cocking handle is cocked it would eject the previous empty 
shell and load a new round.
