AR15 (M4), M16 made by manufacturer ICS from Taiwan in EBB (Electronic Blow Back) version.

This gearbox is manufactured from one solid block of aircraft aluminium (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-aluminium gearboxes. We are manufacturing these gearboxes on our precise CNC milling machines in our factory.

Package includes CNC Upper Gearbox ICS AR15 (EBB), set of screws.

We made some useful improvements into our CNC gearboxes V2:

Spring holders have grooves, so the springs for tapped plate and trigger switch will not jump off.
All threads are now shaped instead of cutted for better strength.
Both gearbox parts are centered by milled grooves and edges.
For better durability, we added more material around cylinder head part of the gearbox, this was the most critical part and we added 100% more material where huge radius is.
Outer edges are now cutted off.
CNC upper gearbox ICS AR15 (EBB) has protective anodizing, even when it is problematic to anodize aluminium 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 grey spots with rotten look).

CNC gearbox can be installed only in airsoft replicas made by ICS. 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 colour.

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!!
