This gearbox is manufactured from one solid block of aircraft aluminum (Dural)\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eEN AW 7075 T651\u003c\/strong\u003e, which has higher strength (\u003cstrong\u003e590MPa\u003c\/strong\u003e), than common construction steel (\u003cstrong\u003e390MPa\u003c\/strong\u003e). Because of used material, our gearboxes have the\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003ebest durability and resilience\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ethan 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.\u003c\/p\u003e\n\u003cp\u003eSplit gearbox means, that this gearbox is designed as a\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003etwo part\u003c\/strong\u003e, Upper and Lower.

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.\u003c\/p\u003e\n\u003cp\u003eRecommended nozzle length is\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e21,3mm\u003c\/strong\u003e. 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.\u003c\/p\u003e\n\u003cp\u003ePackage includes: CNC Split Gearbox V2 (8mm) – QSC in chosen color, set of screws and QSC spring guide.\u003c\/p\u003e\n\u003cp\u003eWe made some useful improvements into our CNC split gearboxes V2:\u003c\/p\u003e\n\u003cul type=\"disc\"\u003e\n\u003cli\u003eSpring holders have grooves, so the springs for tapped plate and trigger switch will not jump off.\u003c\/li\u003e\n\u003cli\u003eAdded groove for safety lever, so it will hold during installation.\u003c\/li\u003e\n\u003cli\u003eAdded groove for trigger spring, for better fitting.\u003c\/li\u003e\n\u003cli\u003eAOE control hole.\u003c\/li\u003e\n\u003cli\u003eSockets for bushings\/bearings have smaller diameter about -0,02mm (7,98mm), for non-overturning the bushings during installation.

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.\u003c\/p\u003e\n\u003cp\u003eSpace for trigger switch is designed for compatibility with trigger switches, trigger units from common manufacturers for example: Gate, etc.\u003c\/p\u003e\n\u003cp\u003eCNC gearbox V2 has\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eprotective anodizing\u003c\/strong\u003e, even when it is problematic to anodize aluminum\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eEN AW 7075 T651\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e(Dural), because of its high strength and hardness.

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.\u003c\/p\u003e\n\u003cp\u003eYou can use in our CNC gearbox\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eany spring of your choice\u003c\/strong\u003e, but be aware that stronger springs will result in lower durability.\u003c\/p\u003e\n\u003cp\u003e!! do not use MAXX cylinder head !!\u003c\/p\u003e\n\u003cp\u003eInstallation of the inner parts and gearbox\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003erequires professional knowledge, experience and skills\u003c\/strong\u003e.

This is the main problem with a lot of inner and outer parts from different manufacturers which can be same product, but with different dimensions. We recommend using only parts from manufacturers with Tokyo Marui compatible parts, where should not be a problem with compatibility with our CNC gearbox.\u003c\/p\u003e","brand":"retro arms","offers":[{"title":"Default Title","offer_id":44681407627491,"sku":"6576","price":225.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0534\/3074\/7324\/files\/2680_split-hop_3203.png?v=1781666943","url":"https:\/\/dmzcanada.com\/products\/copy-of-retro-arms-cnc-split-gearbox-v2-8mm-qsc","provider":"DMZ  Paintball \u0026 Airsoft","version":"1.0","type":"link"}
