Specna Arms CNC ME PRO Hop-Up Chamber for M4/M16 (by Maxx Model)

A high-quality aluminum, precisely CNC machined recoil unit made by Maxx Model, suitable for electric M4/M16 airsoft guns. This recoil unit is compatible with, among others, Specna Arms, Tokyo Marui and similar electric airsoft guns.

Hop-up adjustment is in line with the current trend, with a rotary type. The rotary hop-up adjustment keeps the settings well in place and allows for very precise hop-up adjustment. So there is no longer a problem with hop-up "wandering". The pusher arms included in the package allow the use of both standard hop-up rubbers and IR/R hop-ups. Maxx Model hop-up chambers are designed to work best with 21.00-21.25mm AEG nozzles and are sized to be compatible with parts from almost all tuning part manufacturers. The inner barrel is attached to the hop-up unit with a CNC machined plastic so-called Delrin Locking C-Clip, which ensures that the barrel remains firmly attached to the hop-up unit. The barrel is centered with the brass centering ring included. The Maxx Model hop-up unit also improves tightness and can therefore increase the weapon's output power.

Compared to other Maxx Model hop units, the PRO model has a lever/mechanism that prevents bullets from falling out of the magazine when removed.
