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!

For a sturdy upgrade to your AEG the FPS X-Ring is a piston head seal with a quadrilobate section, which during dynamic stresses are not subject to seal rounding.

X-Rings have less wear than O-Rings as they require less radial pre-stress which results in lower contact pressure.
A lubricant reservoir can be created between the sealing lips using silicone.

Installing this ring will optimise the sealing effect thanks to a better pressure distribution due to the square section.
The X-Ring eliminates any negative effects due to the closing line of the mould, as this is located in the groove between the two lips.

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. 

If you're looking for a strong and lightweight nozzle for your Airsoft AEG, this is worth a look!

A replacement original KRYTAC part which fits version 2, 3, 6 and 7 gearboxes. This cylinder is a Type 1, meaning it has a port in the side intended to reduce the air volume for use on short barrelled platforms (<363mm inner barrel) and prevent the "suck back" phenomenon.

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!

An AEG cylinder head for version 2 gearboxes found in M4/AR15 AEGs and SMG-5 AEGs. This KRYTAC part features a dampening pad, intended to reduce the noise from the piston impacting the cylinder head and give you a smoother sounding gearbox. The cylinder head is constructed from high density polymer with a brass inner nozzle and a rubber dampening pad.

The Bolster Armouries AOE Correction Washer is the perfect easy upgrade for your Airsoft AEG. It fits behind the piston head and ensures your replica has the perfect angle of engagement. This is the angle at which the first tooth of the piston toothing comes into contact with the toothing of the sector gear. If the AOE is incorrectly adjusted, the piston guiding rails and the first piston tooth are subjected to increased wear.

The correct AOE adjustment significantly increases the lifetime of a piston, it can also reduce the chance of your Airsoft platform jamming, which often occurs when the angle of correction is not correct. The FPS will also be more consistent due to a smoother and more precise engagement when firing the AEG.

Treat your Airsoft AEG to the Bolster Armouries AOE Correction Washer and watch as its performance becomes more consistent and the piston survives many more skirmishes.
