Like the PRO chamber, it includes an adjustable feeding shaft.\u003c\/p\u003e\n\u003cp data-start=\"414\" data-end=\"970\"\u003eNew features include an adjustable nozzle shaft, designed to shift the chamber slightly forward when necessary. This is particularly useful for tuning the chamber’s longitudinal position—helping to improve feeding reliability or alignment with the magazine. The position can be adjusted in 0.2 mm increments using the included shims. Please note that this feature may require the use of nozzles with different lengths. The adjustable nozzle shaft will be available in multiple outer diameters, allowing you to choose the best option for your gearbox shell.\u003c\/p\u003e\n\u003cp data-start=\"972\" data-end=\"1244\"\u003eAnother new feature of the ULTRA chamber is the inner barrel securing mechanism.

This gearbox is manufactured from one solid block of aircraft aluminum (Dural) EN AW 7075 T651, which has higher strength (590 MPa) than common construction steel (390 MPa). Because of the material used, our gearboxes have better durability and resilience than common zinc-aluminum gearboxes.

Having a split gearbox has many advantages, such as easier installation of the inner parts.

In this design, you need to secure the spring guide with a screw—commonly, in AR15 (M4) replicas, this is done with the stock screw. In situations where you have folding stocks or no stock at all, you must secure the spring guide with a QSC screw. Otherwise, the spring guide may get stuck with the spring.

We are manufacturing these gearboxes on our precise CNC milling machines in our factory. \u003cbr\u003e\u003cbr\u003eDetail in bracket (8mm) means diameter for bushings\/bearings. Split gearbox means that this gearbox is designed with two parts: Upper and Lower. Having a split gearbox has many advantages. For example: much easier installation of the inner parts into the gearbox. \u003cbr\u003e\u003cbr\u003eDuring installation of a cylinder set, there is no need of removing the whole gearbox from your receiver, only the upper part can be dismounted because its 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. The 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. \u003cbr\u003e\u003cbr\u003ePackage includes: CNC Split Gearbox V2 (8mm) – QSC in chosen color, set of screws and QSC spring guide. \u003cbr\u003e\u003cbr\u003eWe made some useful improvements into our CNC split gearboxes V2: \u003cbr\u003e\u003cbr\u003e- Spring holders have grooves, so the springs for tapped plate and trigger switch will not jump off. \u003cbr\u003e- Added groove for safety lever, so it will hold during installation. \u003cbr\u003e- Added groove for trigger spring, for better fitting. \u003cbr\u003e- AOE control hole. \u003cbr\u003e- Sockets for bushings\/bearings have smaller diameter about -0,02mm (7,98mm), for non-overturning the bushings during installation. The socket edges are cut down for better installation. \u003cbr\u003e- We enhanced grooves for wiring for 1mm, you can now use wirings with 2,5mm diameter. - Added protecting edge for wiring against the motor. \u003cbr\u003e- All threads are now shaped instead of cut for better strength. \u003cbr\u003e- Both of the gearbox parts are centered by milled grooves and edges. \u003cbr\u003e- Added hole for releasing anti-reverse latch. \u003cbr\u003e- 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 is huge radius. \u003cbr\u003e- Added groove for anti-reversal latch spring, so it will not jump off. \u003cbr\u003e- Outer edges are now cut off.\u003cbr\u003e\u003cbr\u003eRetroArms gearbox has quick spring change system (QSC), where you can remove the whole spring guide with a hex key and change the spring without 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. \u003cbr\u003e\u003cbr\u003eSpace 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). \u003cbr\u003e\u003cbr\u003eCNC gearbox can be installed only in Airsoft replicas with Tokyo Marui compatible standard. That means even the inner parts. Do not use brute 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 brute force, if you want to be sure that screws will sit perfectly, use thread glue or thread locker. \u003cbr\u003e\u003cbr\u003eYou can use in our CNC gearbox any spring of your choice, but be aware that stronger springs will result in lower durability.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003e!! do not use MAXX cylinder head !!\u003c\/strong\u003e \u003cbr\u003e\u003cbr\u003eInstallation of the inner parts and gearbox requires professional knowledge, experience and skills.
