Lonex M4 Air Group Set

To avoid the hassle of choosing from the multitude of parts available on the market, you can opt for a complete set responsible for the pressure in the replica. Thus, the set includes: piston head, cylinder head, cylinder, and nozzle, all ready to be installed in gearboxes that are 100% compatible with each other.

This set is intended for the version 2 gearbox found in M4 type replicas with a barrel length between 290 and 363 mm.

The piston head is made of reinforced polyacetal and features ventilation holes for the expansion of the o-ring, while on the opposite side it is equipped with a pressure bearing for improved efficiency in spring compression.

The cylinder head is made of aluminum and is equipped with a double o-ring for better sealing, while the front part has a shock-absorbing pad, both made of rubber.

The cylinder is made of high-quality steel and features external grooves.

The nozzle is also made of polyacetal and has an o-ring inside for better compression against the cylinder head.

Another advantage of the complete set is the reduction in acquisition costs.
