Laylax Picatinny Rear Stock Base for TM M4 Patriot High Cycle – Precision, Strength & Modularity for Your Custom Build

Upgrade your Tokyo Marui M4 Patriot High Cycle with enhanced stability, modularity, and mounting options using the Laylax Picatinny Rear Stock Base. Designed by Laylax/Prometheus—one of the most respected names in premium Japanese airsoft engineering—this rear stock adapter transforms the compact TM Patriot platform into a more versatile, sling-friendly, and accessory-ready setup built for performance-focused players.

Whether you’re customizing for CQB dominance, improved ergonomics, or enhanced weapon handling, this precision-machined stock base delivers the reliability and compatibility you need.

Lightweight & Durable Aluminum Alloy Construction

Crafted from high-quality lightweight aluminum alloy, the Laylax stock base offers the perfect balance between strength and minimal added weight. The robust construction ensures a rock-solid fit while maintaining the Patriot’s lightweight handling characteristics—a must-have for players who demand fast movement, tight angles, and responsive rifle control during high-intensity CQB matches.

This durability ensures long-term performance, even under demanding field conditions where cheap plastic adapters often fail. Laylax has engineered this component to be rigid, professional-grade, and ready for hard use.

Integrated Picatinny Rail for Unmatched Modularity

The highlight of this upgrade is its rear-mounted Picatinny rail, giving players the flexibility to attach a wide range of stock systems, accessories, and adapters. Unlike standard fixed stock mounts, the Picatinny interface makes the M4 Patriot far more customizable, allowing for:

• Folding stock adapters

• Adjustable combat stocks

• Compact PDW-style stocks

• Specialty modular setups, depending on your build

This adaptability is especially valuable for players who want to tailor their rifle to fit their body, play style, or specific mission role.

Equipped With a QD Sling Swivel Mount for Enhanced Mobility

The Laylax Rear Stock Base includes an integrated QD sling mount, giving you fast, reliable attachment points for modern sling setups. This feature allows players to transition smoothly between shoulders, adjust rifle tension mid-game, and maintain retention during movement.

Whether you run a single-point sling for CQB or a two-point sling for precision engagements, the QD mounting capability dramatically improves handling and ergonomics.

Compatible With Laylax Rail Stock Pipe Adapter (Sold Separately)

For players seeking an even deeper level of customization, the Picatinny rail works seamlessly with the Laylax Rail Stock Pipe Adapter (sold separately). Once attached, this adapter lets you mount a wide range of M4 AEG buffer tube stocks, including:

• Standard M4 LE stocks

• SOPMOD/Crane-style stocks

• Minimalist lightweight stocks

• Fully adjustable tactical stocks

This expands the Patriot’s potential far beyond its compact factory configuration, giving you the option to build anything from a stable long-range platform to an ultra-compact PDW.
