  • CNC Aluminium construction
  • Replacement original part
  • Compatible with CYMA CM.057 & Real Sword SVD

If you need a new nozzle for your CYMA CM.057 or Real Sword Dragonov SVD, CYMA has you covered! The Aluminium Nozzle for CYMA/Real Sword SVD/SVU is constructed from CNC machined aluminium and compatible with the CYMA CM.057 SVD/SVU AEG series and the Real Sword Dragunov SVD AEG. 

This is a replacement original part specifically designed for the Real Sword pattern SVD gearbox used in the CYMA CM.057 series and is not compatible with A&K SVDs or others. If you've built a beast of a DMR with your SVD and you want to get ahead of any potential parts failures this is a great part to have in the toolbox!

  • Alloy construction
  • Replacement original part
  • For CYMA CM.098 series SR25 AEGs

If you've lost an SR25 selector switch, this should be helpful! The CYMA Selector Switch Set for CM.098 SR25 AEGs is a replacement original parts set for the CM.098 SR25 series and includes the left and right side selector switches, mounting screws, springs and ball bearings for that lovely "click" between modes. 

The switches themselves are constructed from alloy and match the KAC-style selectors found on the CM.098 series, including the scallop on the right side selector and the undercut on the left side selector to allow for full auto fire. Selector switches are always going missing, but with this set handy, your CM.098 won't miss a beat even if the worst happens!

  • Stainless steel construction
  • Ribbed for reduced heat build-up
  • Fits CYMA/Real Sword SVD & CA/CYMA SR-25

If your CYMA CM.098 or CM.057 needs a revamp, the CYMA Stainless Steel Cylinder for CM.057 SVD & CM.098 SR-25 AEGs should be of use. This stainless steel cylinder is ribbed to promote heat dissipation and polished on the inside for minimal friction. 

This cylinder is a standard bore unported cylinder and is compatible with version 2 long gearboxes found in CA/A&K SR-25 AEGs and CYMA CM.098 SR-25 AEGs and also fits the Real Sword spec SVD gearbox used in the CYMA CM.057 SVD/SVU series and the Real Sword SVD Dragunov. 

  • CNC Aluminium construction
  • Double O-Ring configuration
  • For CYMA CM.057 & Real Sword Dragunov

If you need a new cylinder head to fix up your Dragunov, check this out! The CYMA Aluminium Cylinder Head for CYMA/Real Sword SVD/SVU is constructed from CNC machined aluminium and is fitted with two O-rings to seal any gaps between it and the cylinder for perfect efficiency and minimal air loss. 

The cylinder head also has a sound dampening pad installed on the rear face which reduces gearbox noise and protects the piston head from the force of repeated impacts. A replacement original part for the CYMA CM.057 SVD/SVU series, this cylinder head is also compatible with the old Real Sword Dragunov SVD!

  • Alloy construction
  • Replacement original part
  • Compatible with most SMG-5 AEGs (not K or PDW)

If your SMG-5 trigger is a bit worn out or you have a flat trigger inside and you want a more classic SMG-5 look, the CYMA Trigger for SMG-5 AEG is what you need. This trigger is only for SMG-5 AEGs which use a version 2 gearbox and will not fit the version 3 gearbox equipped SMG-5K and SMG-5PDW series. The trigger itself is constructed from alloy and has the curve of the original SMG-5 trigger, making for an appropriately realistic look. Included with the trigger is a trigger return spring, so if you have lost this part you're in luck!

Maybe you have lost a spring, or your tappet spring got chewed up after a long and hard life? This spring set should give you all you need to get your AR36 doing its dirty work once again!

  • Replacement original parts
  • Includes HOP-up chamber, bucking and nub
  • For CYMA CM.027 SMG-5 series

If you have HOP-up woes with your SMG-5 this could be what you need to fix it up! The CYMA HOP-Up Chamber with Rubber and Nub for SMG-5 AEG is a replacement original part for the CM.027 SMG-5 series but should also work in any TM based SMG-5 AEG (not NGRS variants). The set includes a complete HOP-up unit with the HOP-up arm and also includes a basic HOP-up rubber and nub, giving you everything you need to replace the entire unit in a single package. 

This set is designed for the CM.027 which is a copy of the Tokyo Marui SMG-5 AEG and should also work with similar designs but is not compatible with the Classic Army SMG-5 or the later CYMA CM.041 series SMG-5 AEGs. 

  • Replacement original parts
  • For CYMA CM.098 SR-25 AEG
  • Fix up your old AEG!

  • SR25 Style Gearbox

This SR25 Gearbox set by CYMA is designed to fit right into most SR25 / AR25 / AR10 style Airsoft Rifles / Guns. Included is a Piston, Cylinder, Gear Set, Tappet Plate, Nozzle. This GEARBOX set does not come with the shell, internals only.

  • High speed gear set
  • Fits most Airsoft gearboxes
  • 13:1 Ratio - Great for high ROF builds

Building a speed demon of an AEG? You will need high speed gears to get the most out of it! The CNC steel High Speed Gearset from CYMA has a 13:1 ratio, which means every 13 motor turns the gearbox will cycle once, which is a step faster than standard 18:1 Airsoft gears. These gears pair perfectly with a high speed motor to provide a demonic rate of fire, as can be seen in the latest upgraded versions of CYMA's Platinum series AEGs. This gearset is designed for use with M120 springs and below only, so should be fine for most UK legal Airsoft AEGs but is not suitable for a DMR rifle with high FPS. This gearset is a version 2/3 set so should work in any AEG with a V2/3 gearbox and many others which share the same gears.

  • Complete V2 Gearbox for SMG-5 AEGs
  • MOSFET, High-speed motor & high-speed gears
  • Pre-wired to Deans and ready to drop in!

Whether you are upgrading your SMG-5 or repairing it, the CYMA CM.041G/CM.041H Complete Gearbox E-Edition High-Speed is a great excuse to do both at the same time! This gearbox is a Version 2, designed for CYMA CM.041 series SMG-5 AEGs but should fit most SMG-5 AEGs on the market (not SMG-5K) and also includes a high-speed motor of the long shaft variety.

As the heart of the CYMA E-Edition High-Speed Platinum AEG series, this gearbox is absolutely packed with upgraded parts. Highlights of the internals include the CYMA MOSFET/ETU system, steel high-speed 13:1 ratio gears, an aluminium silent piston head and cylinder head and a quick change spring system. Being a replacement original parts set, this gearbox is the exact setup found in the superb CM.041G and CM.041H AEGs, meaning if you have ever been envious of their performance you can now make your SMG-5 shoot just as nicely!

  • Complete V2 gearbox
  • Compatible with M4/AR-15 AEGs
  • Quick change spring, ETU/MOSFET & high torque motor

If you have had a gearbox failure and you don't fancy opening it up, the CYMA Complete Version 2 Gearbox w/High Torque Motor & ETU is a pre-upgraded and pre-wired replacement which can be installed with minimal effort and no need to solder or open the gearbox shell. As always, we recommend you have some technical experience before installing a new gearbox, but when it comes to Airsoft upgrades this is about as easy as they get.

This gearbox set is designed for M4/AR-15 AEGs and has the correct nozzle length and selector plate for the task and is also pre-wired to a Deans connector so you can benefit from a lower resistance connector for increased electrical efficiency. Also included with the set is a CYMA high torque Neodymium magnet motor, providing a very snappy trigger response and the power to handle stronger springs than a standard motor.

The icing on the cake is the pre-installed MOSFET/ETU which prevents gearbox lock-up on semi-auto, provides further improvements to the trigger response and a boost to the rate of fire. If your M4 gearbox has issues or you want to freshen up an old M4 with a brand new and pre-upgraded gearbox this set would be a fantastic choice, avoiding the messing around and getting you back to shooting with minimal effort!

Maybe you have lost a spring, or your tappet spring got chewed up after a long and hard life? This spring set should give you all you need to get your AK doing its dirty work once again!

If you have damaged your HOP-up unit and are looking for a replacement, CYMA are now offering their original HOP-up units as an aftermarket part.

The gears are constructed from steel and come as a set of 4, replacing all gears inside the unique SVD gearbox. These gears are not compatible with the A&K Dragunov SVD, only the CYMA CM.057 series and the Real Sword Dragunov. 

  • MOSFET & Wiring
  • Replacement original parts
  • For version 2 gearbox equipped AEGs

If your CYMA MOSFET has met its end, or you want a cheap and cheerful upgrade, the CYMA MOSFET for V2 Gearbox; Front Wired is ideal. This MOSFET is a replacement original part for the CYMA Platinum AEG series and should work with any AEG which uses a version 2 gearbox. When installed, this MOSFET should improve trigger response and rate of fire, along with eliminating the chances of your trigger contacts becoming corroded. 

The MOSFET is pre-wired with two sets of spade connectors and is set up for front-wired AEGs. Please note, certain gearboxes will need modification to install this MOSFET/ETU unless they already have a slot in the shell designed for an electronic trigger. We only recommend this part for experienced users!
