CNC split gearbox V2 designed for airsoft replicas AR15 (M4), M16 and other ones with V2 gearbox.
This gearbox is manufactured from one solid block of aircraft aluminum (Dural) EN AW 7075 T651, which has higher strength (590MPa), than common construction steel (390MPa).
Because of used material, our gearboxes have the best durability and resilience than common zinc-aluminum gearboxes.
We are manufacturing these gearboxes on our precise CNC milling machines in our factory. Detail in bracket (8mm) means diameter for bushings/bearings.
Split gearbox means, that this gearbox is designed as a two part, Upper and Lower.
Having a split gearbox has many advantages.
For example much more easy installation of the inner parts into the gearbox.
During setups of you cylinder set, there is no need of removing whole gearbox from your receiver, only upper part can be dismounted, because it‘s mounted on one receiver pin.
This gearbox can be installed even into the receivers AR15 (M4), what are not completely straight, with any AR15 (M4) Hop Up chamber of your choice.
Recommended nozzle length is 21,4mm.
Be aware that nozzle length can be influenced by many factors, for example angle of the tapped plate or different length of front part of the Hop Up bucking.
In these scenarios, you will need a different nozzle length.
Package includes:
CNC Split Gearbox V2 (8mm) – QSC in chosen color, set of screws and QSC spring guide.
We made some useful improvements into our CNC split gearboxes V2:
RetroArms gearbox has quick spring change system QSC, where you can put out whole spring guide with hex key and change the spring without need of opening the gearbox.
In this solution, you need to secure spring guide with screw, commonly with AR 15 (M4) replicas, it is by stock screw.
In situations where you have folding stocks or no stock at all, you have to secure the spring guide with QSC screw.
Otherwise there could be situation, where the spring guide will stuck with the spring.
This is because the spring guide is not fixed in the gearbox but has will for easy removing with hex key.
Space for trigger switch is designed for compatibility with trigger switches, trigger units from common manufacturers for example: Gate, etc.
CNC gearbox V2 has protective anodizing, even when it is problematic to anodize aluminum EN AW 7075 T651 (Dural), because of its high strength and hardness.
If we did not anodize products from this material, there is huge risk of corrosion (huge gray spots with rotten look).
CNC gearbox can be installed only in airsoft replicas with Tokyo Marui compatible standard.
That means even the inner parts.
Do not use rude force during installation.
Use only 1Nm tightening moment on screws, otherwise the screws will overturn in heads.
There is no need of tightening screws with rude force, if you want to be sure that screws will sit perfectly, use thread glue or thread color.
You can use in our CNC gearbox any spring of your choice, but be aware that stronger springs will result in lower durability.
!! do not use MAXX cylinder head !!
