M4G Hop-Up chamber for VSR/GBB barrel [MAXX MODEL]

M4G- The chamber is dedicated to barrels and buckings in the GBB/VSR standard for AEG replicas

A new aluminum chamber, manufactured using CNC technology by Maxx Model, the M4G models, has been designed with precision performance in mind for M4 series replicas. Compatible with replicas in the VFC/Marui M4/M16 standard, this chamber stands out with the highest quality workmanship, guaranteeing repeatability and accuracy with every shot.
The chamber is equipped with a locking mechanism that automatically releases when the magazine is inserted, and prevents balls from falling out of the feeding channel when the magazine is removed. The side guides of the chamber have additional copper plates, which can be used both to extend the guides and to precisely set and level the chamber in the outer barrel.
A precise adjustment knob provides a wide range of hop-up pressure settings and eliminates the risk of accidental misalignment. The new solution for the locking pin of the pressure arm, based on an o-ring, allows for quick disassembly of the chamber and replacement of the spacer without the use of tools. Additionally, a specially designed barrel locking clip prevents it from changing its position, significantly improving shot accuracy.
The chambers in the M4G models have been equipped with washers that allow precise spacing of the chamber in relation to the frame, enabling accurate calibration of the nozzle in relation to the hop-up bucking.

An essential step to install the GBB/VSR bucking is to remove the side guide of the bucking. The Maple Leaf Wonder and Super series buckings do not require modification to be installed in the M4G chamber.

Barrels in the AEG standard as well as buckings will not fit this chamber
