Silverback MDR-X Micron, V3 - Black

The Silverback MDR-X MICRON is a high-performance airsoft replica officially licensed by Desert Tech. Built to mirror the real MDR-X 5.56 rifle, this model blends authentic design, robust construction, and cutting-edge internals into one sleek bullpup package.

Compact Bullpup Design with Realistic Build

Thanks to its bullpup layout, the MDR-X MICRON offers a shortened overall length without compromising barrel size, making it ideal for close-quarters combat (CQB) while retaining accuracy at longer ranges.

The outer body combines a 6000 series aluminum receiver, outer barrel, and muzzle brake, with reinforced PA6 nylon polymer used on the stock, grip, and handguard. A rubber buttpad ensures better shoulder comfort, and the rifle features full ambidextrous controls (fire selector and mag release), along with QD sling mounts for convenient carrying. The handguard uses M-LOK slots at 3 and 9 o’clock for mounting accessories.

High-Quality Gearbox – Ready for Any Mission

Inside, the MDR-X MICRON boasts a precision-engineered gearbox with premium materials and thoughtful design:

• CNC aluminum wide bore cylinder (26 mm – 19% wider than standard AEG) for greater air volume (up to 22.5cc with 75% ventilated design)

• Quick-change spring system for easy FPS adjustments

• CNC aluminum cylinder head with NBR piston damper and stainless steel nozzle

• CNC ventilated piston head with FKM O-ring and POM glider ring

• CNC aluminum and stainless steel spring guide with thrust bearing and 3-lug alignment design

• “Tappet plate-less” architecture for greater reliability

• CNC aluminum piston body with hardened 16-tooth MIM steel rack

• 18:1 torque-up gearset, made of hardened MIM steel

• ADC12 aluminum gearbox shell with 10 mm ball bearings

• Neodymium high-torque motor (19,000 RPM, 11.1V ready, short axis)

This gearbox was built not only to deliver consistent performance but to handle stress from demanding setups with ease.

Advanced Programmable Electronics (ECU)

The built-in Electronic Trigger Unit (ETU) and programmable ECU (developed with T238) give players full control over their weapon’s behavior:

• Compatible with 11.1V and 7.4V LiPo batteries

• Hall Effect sensors monitor gear cycle and fire selector position

• Customizable firing modes: semi, burst, binary, DMR cooldown

• Rate of fire (ROF) settings, pre-cocking, active braking, and sleep mode

• Low-voltage battery protection and MOSFET thermal safety

• Compatible with brushless motors (check manual for limitations)

This system allows you to tailor the gun’s behavior to your playstyle, whether you’re an aggressive CQB player or a precision shooter.

Precision Hop-Up System and Inner Barrel

The hop-up design is just as refined:

• Constructed from durable polycarbonate with TDC-style rotary ring

• Incremental “click” adjustment using ball plungers (36 positions)

• Two nubs included:

  • Low nub (installed): for standard BBs, range 0–750 µm

  • High nub (included): for heavy BBs (0.32g+), range 500–1250 µm

• 330 mm brass inner barrel, 6.05 mm bore, AEG-style hop cut, chemically treated for durability

• 70° flat hop bucking for stable BB flight path and better consistency

This setup provides accurate, consistent shots — whether you're running 0.25g or pushing heavier ammo for precision builds.

Included in the Box

• MDR-X MICRON rifle

• 120-round AR15-style magazine

• 4 pairs of magazine spacers (PA6 nylon) to reduce wobble

• Two additional power springs for quick tuning

• Pin puncher for fast battery access and field disassembly

• 2mm and 5mm Allen keys

• High hop-up nub for heavy BBs (0.32g and up)

• Spare ball plunger for hop-up unit

The MDR-X MICRON is not just a replica — it's a versatile platform designed for serious airsoft players. Whether you're clearing rooms in tight CQB environments or laying down precision fire on open fields, this rifle offers the performance, durability, and customization you need to stay ahead.
