Silverback MDRX Cylinder Head with Nozzle – CNC Aluminium

The Silverback MDRX Cylinder Head with Nozzle is a precision-engineered replacement or upgrade component designed for players running Silverback MDRX gearbox platforms. This complete assembly combines a robust CNC-machined aluminium cylinder head with an integrated stainless steel nozzle, delivering the durability and consistency that separates premium airsoft builds from budget alternatives.

Key Features

• CNC Aluminium Cylinder Head – superior durability and precise tolerances for consistent air compression
• Stainless Steel Nozzle – corrosion-resistant and optimised for reliable feeding and sealing
• NBR Piston Damper Included – reduces piston shock and extends gearbox component lifespan
• FKM O-Ring Sealing – premium elastomer ensures airtight seals across temperature ranges
• Return Spring Included – complete assembly ready for installation into compatible MDRX gearboxes

Real-World Use Cases

Whether you’re rebuilding a worn MDRX gearbox, upgrading internals for higher performance, or maintaining a milsim platform rifle, this cylinder head assembly is an essential component. CNC aluminium construction withstands the heat and stress of rapid semi and full-auto fire without warping, whilst the stainless steel nozzle resists corrosion from moisture and prolonged storage. The included damper and FKM ring mean fewer leak points and more consistent shot-to-shot performance – critical in tournament and organised skirmish scenarios.

Compatibility & Upgrades

This component is designed exclusively for Silverback MDRX gearbox systems. When installing, ensure all seals (o-rings and FKM ring) are clean and lightly greased with silicone-based lubricant for optimal compression and longevity. Pair with compatible MDRX piston sets, springs, and gears for a complete internal upgrade.

UK Legal & Site Notes

As an internal gearbox component, this cylinder head assembly is unrestricted and legal to own and modify in the UK. Many UK airsoft sites permit internal upgrades freely; always check your site’s chrono limits and FPS caps before game day. Cylinder head modifications can affect air volume and compression – test your rifle after installation.
