This Gun features an Electric Blow Back System.
The CXP-UK1 comes standard with an ICS POM reinforced piston, metal H-UP unit and a reinforced pinion and bevel gear via MIM process. These enhancements make it one of the most durable AEGs out of the box. The body pins have tracks on them keeping them attached to the lower receiver when disassembling the gun. The gun also has an ambidextrous charging handle allowing both right handed and left handed shooter to be comfortable. The selector switch also releases the spring tension when moved to the safe position – another feature that will prolong the life of your gun.
