The Maxx Model CNC aluminum hop-up chamber, M4i – PRO, is designed and manufactured to work precisely and with extreme accuracy with ICS CXP/CS4/EBB (including older models) M4/M16 style AEGs.
The special feature of the new Maxx Model M4i – PRO is the alignment adapter located at the nozzle inlet, ensuring unprecedented precision in aligning the barrel, nozzle, and hop-up unit.
The hop-up adjustment uses a rotary-style mechanism, controlled by a large numbered adjustment ring. The rotary hop-up design allows for highly accurate and stable hop-up settings. The hop-up unit comes with different pressure arms, making it possible to optimize the unit for use with standard hop-up rubbers or R-hop patches.
On the sides of the hop-up unit are removable brass side wings that slide smoothly into the grooves on the outer barrel.
