The biggest advantage of the Mark IV series over the previous Mark II and III models is the new simplified disassembly system.
The firearm can now be easily disassembled with the press of a single button. The lower and upper parts of the firearm are connected by a pin, and when disassembling, the upper part tilts upward. This eliminates the complex and time-consuming disassembly process found in the Mark II and III series. Other new features include adjustable sights, which are available as standard on all models. Additionally, the Hunter model is equipped with a fiber optic front sight.
