6MMPROSHOP AK SPETSNAZ OP. // CYMA AK AEG // STEEL RECEIVER // M-LOK // V3 GEARBOX // MILLED STYLE // 380–400 FPS

Combine classic AK durability with modern tactical modularity using the 6mmProShop AK Spetsnaz Op. Airsoft AEG Rifle with Steel Receiver & M-LOK Handguard by CYMA – Milled Style Receiver. Built for players who want the rugged construction and proven gearbox architecture of an AK while gaining the accessory support and adjustability expected from a modern airsoft rifle, the Spetsnaz Op. delivers a strong balance of realism, durability, and field-ready versatility.

At its foundation is a riveted stamped steel receiver, steel outer barrel, and full-metal Version 3 gearbox with reinforced internal components. Around that proven core, 6mmProShop and CYMA add a full-length M-LOK handguard, hinged 20mm optics rail, ergonomic pistol grip, adjustable M4-style stock, and multiple sling mounting options.

With a manufacturer-rated 380–400 FPS range and a 500-round hi-cap magazine included, this modernized CYMA AK AEG is ready to serve as a distinctive primary platform for outdoor games, MilSim-inspired loadouts, and players who simply want something different from another conventional M4.

01 // RIVETED STAMPED STEEL RECEIVER

A proper AK-style airsoft rifle should feel substantial, and the Spetsnaz Op. starts with a riveted stamped steel receiver.

Steel construction provides the rifle with the rigidity, durability, and realistic weight that experienced AK players look for.

The receiver is paired with a steel outer barrel, further contributing to the solid feel of the platform.

This particular configuration features the distinctive Milled Style Receiver appearance, combining traditional AK-inspired styling with the rifle’s considerably more modern furniture and accessory system.

02 // FULL METAL VERSION 3 GEARBOX

Internally, the Spetsnaz Op. uses a full-metal Version 3 AEG gearbox with reinforced internal components.

The V3 gearbox architecture is widely associated with AK-style electric airsoft rifles and provides a proven foundation for regular field use.

For players who prefer platforms built around established AEG technology, the CYMA-based drivetrain gives the Spetsnaz Op. a familiar internal foundation beneath its highly modernized exterior.

As with any AEG, internal compatibility should always be confirmed before ordering aftermarket upgrade components.

03 // FULL-LENGTH M-LOK HANDGUARD

The traditional AK front end has been replaced with a modern full-length M-LOK handguard.

This dramatically increases the rifle’s accessory flexibility.

Compatible M-LOK positions can support appropriate:

Rail Sections
Vertical or Angled Grips
Weapon Lights
Laser Units
Other M-LOK Accessories

The result is an AK platform that can be configured around a player’s preferred equipment rather than being limited by traditional furniture.

It also gives the rifle its aggressive modern Spetsnaz-inspired appearance.

04 // HINGED 20MM OPTICS RAIL

Optics mounting can sometimes be challenging on traditional AK platforms, but the Spetsnaz Op. addresses this with a hinged rail positioned over the dust cover.

The 20mm RIS-style mounting surface provides a convenient location for compatible optics and accessories.

Players can configure the rifle with an appropriate red dot, reflex sight, or other compatible aiming system without relying exclusively on a traditional AK side-mount solution.

The hinged design also maintains the rifle’s distinctive modern tactical profile.

05 // ADJUSTABLE M4-STYLE STOCK

At the rear, the rifle uses a buffer tube with an adjustable M4-style stock.

This gives players considerably more flexibility in adjusting the rifle’s overall fit compared with a fixed traditional AK stock.

The adjustable length can be useful for accommodating different player sizes, protective equipment, plate carriers, and seasonal clothing.

It also opens the door to compatible stock options for players who want to further personalize the rifle’s appearance and ergonomics.

06 // ERGONOMIC PISTOL GRIP

The Spetsnaz Op. features a comfortable ergonomic-style pistol grip rather than a basic traditional AK grip.

This complements the modernized handguard and adjustable stock while providing a more contemporary feel.

For players transitioning from M4-style rifles to an AK platform, the modern grip and adjustable stock can make the overall handling characteristics feel considerably more familiar.

07 // MULTIPLE SLING MOUNTING OPTIONS

A practical field rifle needs appropriate sling support.

The Spetsnaz Op. includes a barrel-mounted sling loop along with QD sling swivel mounting points around the stock system.

This gives players several options for integrating a compatible sling into their equipment setup.

Whether building a traditional two-point arrangement or another field-appropriate configuration, the rifle provides useful attachment options directly from the factory.

08 // 500-ROUND HI-CAP MAGAZINE INCLUDED

The rifle includes a 500-round high-capacity AK AEG magazine.

That substantial capacity is particularly useful for longer recreational games where players want to reduce the frequency of magazine changes.

It also means the rifle arrives with a compatible magazine, allowing players to begin building their AK loadout around the included configuration.

Additional magazine compatibility can vary, so fitment should be confirmed when purchasing aftermarket AK AEG magazines.
