This is brand new support cube for AK type Hop-Up chambers. Support cube is manufactured from aircraft dural EN AW 7075, what have strenght of steel and weight of aluminium. It is best material for high performance parts. Cube is milled on CNC milling machine and has protective anodizing of 5µm black and red color (0,005mm). Cube supports Hop-Up chamber in AK's body in straight line, so it won't overturn. The original part in weapon's body is made from plastic and don't have any function. Reloading the magazines is problematic because of wrong leading into the body. So we made a support cube with plate, which preventes from wrong putting magazine into the body. Magazine clip is leaded by support cube's plate into the right position in body. It solves problematic reloading with magazines and offer's even fast reloading without damaging your mags.
