Airsoft Hop Up FLATPRESSING sistem. Long Hop.

cults3d

System for rotativ Hop Up chamber of AEG replicas. This system aims to keep the nub fixed and press through the entire window of the Inner Barrel over the hop up rubber. The arm is designed to exert on the nub and implicitly on the Rubber a pressure perpendicular to the direction of propelling the ball. The nub is designed with progressive elasticity, so the first part of the nub has a low resistance to allow the ball access to the hop up chamber, in the middle it develops a normal resistance that progressively decreases allowing the ball to calm down after the shock resulting from the contact and sending the ball to the barrel with a rectilinear continuous trajectory. This system is suitable for hop up R-HOP. Must rectify internal barrel window at 7,5mm long, or cut the back of the NUB at 4mm Tested on a personal R-Hop system that I will make public soon.
