New generation gearbox V2

25. 08. 2016

Based on feedback and experience from you and tech guys, we totally reworked gearbox ver. II.

Old data was deleted and everything was changed. The compatibility is now our main goal, so this new gearbox is compatible with basic parts and some known issues were repaired.

After one year of experience and testing, we have final version of our ANC gearbox – Airsoft Norms Compatible.

Material

With great experience, we are still using aircraft dural EN AW 7075. Whole gearbox is milled from one piece of material. No casting, no half-milling. Only one solid piece of dural. Unfortunetly after changing connection technology, gearbox now 20% larger. Quality and functionality is much more important than low cost CNC gearboxes.

Changelog

First big and noticable change is rounded upper part. Now you can fit this new generation gearbox to every M4 body without any customizations.
Inside of gearbox was reworked too. Place for trigger switch or trigger units is now compatiable with common parts. With that came also change of cut-off lewer unit.
We did a lot of edge cutting on whole gearbox, so it will now fit much easier in body.
After some experience with pin-connecting on both halves, we decided to remove them. We did on one half protrusions and the other half have grooves. So no more jamming, rusting or falling out. Both halves are now connected perfectly and easly removable.
Front part where is hop-up chamber was reworked, you can now use for example Prowin chambers (we do not recommend them). We recommend our RetroArms hop-up chambers what are made for this gearbox.
Upper part of gearbox has now ratchet for cocking lever.
Springs holders are now milled (they were screwed before).
Bushing holes have now 7,98 mm diameter. After some experience, this is the best diameter for holding 8 mm bushings and not deforming them. Bushing housing edge was cutted for better instalation under 90° angle.
We removed trigger position pin, this part is now milled.

All these changes + different dimensions of new gearbox leads to better compatiblity with common parts of different manufactures and easy instalation of them.
