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

Bring modern tactical capability to one of airsoft’s most proven platforms with the 6mmProShop AK Spetsnaz Op. Airsoft AEG Rifle with Steel Receiver & M-LOK Handguard by CYMA – Stamped Receiver. Built around a rugged riveted stamped steel AK receiver and steel outer barrel, this modernized AEG combines classic AK construction with contemporary accessory mounting, adjustable ergonomics, and the proven reliability of a full-metal Version 3 gearbox.

This Stamped Receiver model is designed for players who want an unmistakable AK foundation without being limited to traditional furniture. A full-length M-LOK handguard, railed dust cover and gas tube, ergonomic pistol grip, buffer tube, and adjustable M4-style stock transform the platform into a highly configurable modern airsoft rifle.

Internally, CYMA’s established Version 3 AEG gearbox architecture with reinforced components provides the mechanical foundation, while the included 500-round hi-cap magazine gives the rifle substantial capacity straight out of the box.

With a manufacturer-rated velocity of 380–400 FPS, the AK Spetsnaz Op. is a serious modern AK platform built for players who value steel construction, modularity, and distinctive tactical styling.

01 // TRUE STAMPED STEEL AK CONSTRUCTION

The heart of this Spetsnaz Op. configuration is its riveted stamped steel receiver.

Unlike lightweight polymer-bodied AK platforms, the use of steel gives this rifle the substantial feel many players expect from a premium AK-style replica.

The receiver is complemented by a steel outer barrel, adding additional rigidity and contributing to the realistic weight and balance of the rifle.

For players specifically searching for a steel receiver CYMA AK AEG, this construction is one of the Spetsnaz Op.’s strongest features.

02 // FULL METAL VERSION 3 GEARBOX

Inside the rifle is a full-metal Version 3 gearbox with reinforced internal components.

The V3 gearbox is one of the most established internal architectures used in AK-style airsoft AEGs, giving the Spetsnaz Op. a familiar foundation for maintenance and compatible upgrades.

Rather than creating a proprietary internal system to match the rifle’s modern exterior, CYMA keeps the platform based around proven AEG technology.

This makes the Spetsnaz Op. an attractive option for players who want a modernized rifle without abandoning the familiar characteristics of an AK AEG.

03 // FULL-LENGTH M-LOK HANDGUARD

Traditional AK furniture has been replaced with a full-length M-LOK handguard, dramatically expanding the rifle’s customization potential.

Compatible mounting positions can accommodate a wide range of appropriate M-LOK accessories, including:

Rail Segments
Foregrips
Weapon Lights
Laser Units
Other Compatible M-LOK Accessories

The streamlined M-LOK system provides useful accessory space without covering the entire handguard in unnecessary rail sections.

It also gives the Spetsnaz Op. its aggressive, contemporary appearance.

04 // RAILED DUST COVER & GAS TUBE

One major difference between this Stamped Receiver configuration and other Spetsnaz Op. variants is its extensive upper rail system.

The rifle features both a railed dust cover and railed gas tube, creating a long 20mm RIS-style mounting platform across the upper portion of the rifle.

This gives players significantly more flexibility when positioning compatible optics and accessories.

A red dot or reflex sight can be positioned according to personal preference, while additional compatible accessories can make use of the forward rail area.

For players building a modern tactical AK, this extended rail system is a major advantage.

05 // ADJUSTABLE M4-STYLE STOCK

The rear of the Spetsnaz Op. moves away from traditional fixed AK furniture with a buffer tube and adjustable M4-style stock.

The adjustable design allows players to alter the rifle’s length of pull to better match their size, protective equipment, and preferred shooting position.

This can be particularly useful when transitioning between lighter recreational equipment and bulkier plate carriers or MilSim loadouts.

The M4-style buffer tube configuration also gives the rifle a distinctly modern appearance while offering additional customization potential.

06 // MODERN ERGONOMIC PISTOL GRIP

An ergonomic-style pistol grip complements the adjustable stock and M-LOK front end.

The result is a rifle that retains its AK controls and internal architecture while offering a more contemporary handling experience.

Players accustomed to modern M4-style ergonomics may find the combination of the adjustable stock and updated pistol grip more familiar than traditional AK furniture.

07 // MULTIPLE SLING MOUNTING OPTIONS

The Spetsnaz Op. provides multiple options for integrating a compatible sling.

A barrel-mounted sling loop provides a traditional forward attachment point, while QD sling swivel mounting points around the stock support more modern sling configurations.

This gives players the flexibility to configure the rifle around their preferred load-bearing setup.

08 // 500-ROUND HI-CAP MAGAZINE INCLUDED

Included with the rifle is a 500-round high-capacity AK AEG magazine.

The large capacity provides plenty of ammunition for longer recreational games and reduces the frequency of magazine changes compared with lower-capacity options.

Players who prefer MilSim-style loadouts can explore compatible mid-cap magazines separately, while the supplied hi-cap provides an immediately usable high-capacity option.

Magazine fitment can vary between AK brands and generations, so compatibility should always be verified when purchasing additional magazines.
