There are many levels of the Spyder. These are usually divided up into the groups of markers that have mechanical triggers and electronic triggers. But let’s not forget the pump action Spyder Hammer. These markers are manufactured by Kingman International. We won’t go into heavy duty history here of the evolution of the Spyder.
The Spyder has become one of the most copied body types on the paintball market. This is the reason behind the vast amount of upgrades and available modifications available to a new Spyder owner. This also applies to those who are owners of Spyder clones. Most of these markers do use the same parts and many times the parts are interchangeable.
The Kingman Spyder semi-automatics are a stacked tube design. They are also a open bolt blow back type. The blow back part means that part of the gas expelled during firing is used to re-cock the bolt and make it ready to fire again. The basic difference between an open bolt marker and a closed bolt marker is the starting position of the bolt before firing. The open bolt starts with the bolt in the rear position behind the feed tube and a closed bolt starts forward of the feed tube. Several sources claim that closed bolt markers are more accurate than open bolt markers. We say if the physics involved apply to real world guns in their action then it also applies to paintball markers. Typically a closed bolt “bolt action” rifle is much more accurate than it rapid firing counter part of the same caliber.
Lets get on with the mods. The Kingman Spyder is a durable reliable marker right out of the package from the factory, however it has some issues that you can address to make it perform much better.
