Transform Your SMG9 Into a Modular, Tactical Powerhouse

Upgrade your CYMA Platinum SMG9 with the 5KU Adjustable ACR Style Folding Stock, a precision-engineered enhancement designed for players who demand comfort, adaptability, and modern styling. Built to give your SMG9 a more aggressive, mission-ready profile, this ACR-inspired stock delivers a blend of durability, ergonomic performance, and customizable fit—perfect for CQB players, outdoor competitors, or anyone wanting a more refined shooting setup.

Crafted with a balance of aluminum alloy reinforcement and high-strength polymer components, the 5KU ACR stock provides rock-solid stability while staying lightweight and maneuverable. Whether you’re clearing tight corners or posting up for long-range engagements, this stock ensures your SMG9 stays controlled, comfortable, and fully adaptable to your playstyle.

ACR-Inspired Tactical Design

One of the standout features of this upgrade is its authentic ACR-style folding stock, giving your SMG9 a sleek, modern, and highly functional platform upgrade. The folding mechanism allows players to instantly reduce the rifle’s overall length, making it easier to transport, store, and operate in ultra-tight CQB environments.

Fold the stock to navigate cramped interiors or deploy it quickly when you shift into a more controlled shooting position. The ability to switch between compact and stabilized modes makes this stock ideal for mixed-field play where mobility and stability are both essentials.

7-Position Adjustability for a Perfect Fit

The 5KU ACR stock is engineered with 7 adjustable length-of-pull positions, allowing players to fine-tune the overall length for comfort, sight alignment, and playstyle. Whether you prefer a tight, compact shoulder position for rapid movement or a fully extended configuration for stability and accuracy, this stock adapts instantly.

You can adjust it on the fly, ensuring the rifle always fits your stance and loadout—making it easier to engage targets quickly and maintain consistent performance.

Adjustable Cheek Riser for Better Sight Alignment

To support a wide range of optics and sighting setups, the stock includes an adjustable cheek riser. This small but powerful feature ensures your eye lines up perfectly with your red dot, scope, or holographic sight, improving comfort and reducing neck strain during prolonged games.

Better cheek weld = better consistency = better accuracy. The riser gives you the freedom to set your preferred cheek height and maintain the same sight picture every time you shoulder the weapon.

Drop-In Upgrade — No Hassle, No Extra Tools

Designed specifically for the CYMA Platinum SMG9 Airsoft Electric Submachine Gun, this stock fits seamlessly as a drop-in upgrade, requiring little to no modification. Installation is simple, secure, and fast—perfect for players who want an immediate enhancement without complicated fitting or internal adjustments.

Spend more time playing and less time tinkering.

The SMG9 is a high-performance CQB powerhouse, and the stock you attach should match that level of durability. 5KU constructed this stock with a combination of:

• Aluminum alloy for enhanced strength and structural rigidity

The result is a rugged, reliable upgrade that stands strong through fast-paced gameplay, aggressive movement, and extended matches.
