Laylax PSS Under Rail and Magazine Catch for Tokyo Marui VSR-10 Series

Take your bolt-action tactical performance to the next level with the Laylax PSS Under Rail and Magazine Catch for Tokyo Marui VSR-10 Series. Custom-designed by Laylax under their renowned Prometheus Sniper System (PSS) line, this combination kit solves two major limitations of the standard factory VSR-10 setup: limited front mounting options and a recessed magazine release button that can be difficult to operate when wearing gloves.

Heavy-Duty 20mm Picatinny Rail Mount

The integrated under-rail section provides a rigid 20mm Picatinny mounting platform directly beneath the forend stock. Constructed from high-strength aluminum alloy, this rail serves as a solid foundation for attaching tactical bipods, foregrips, weapon lights, or laser designators. Unlike flimsy screw-on stud mounts that can wobble or strip out under heavy rifle weight, this engineered rail assembly distributes forces evenly across the receiver housing, ensuring your bipod stays completely stable when setting up long-range sniper shots.

Extended Ergonomic Magazine Release

Swapping magazines quickly in the field can mean the difference between landing a decisive tag or being pushed by enemy infantry. The included Laylax magazine catch features an enlarged, textured contact surface that extends slightly beyond the stock frame. This subtle enlargement allows you to locate and depress the release catch instantly by feel alone, even in low-light environments or while wearing thick tactical gloves. The drop-in catch retains smooth spring tension, preventing accidental magazine drops during woodland maneuvers while providing crisp, reliable ejection when pressed.

Key Features & Technical Benefits:

• Dual-Upgrade Utility: Combines a sturdy 20mm accessory rail with an enlarged, tactile magazine release button in one kit.

• High-Strength Metal Construction: Premium aluminum build provides maximum durability with minimal weight penalty.

• Enlarged Catch Geometry: Speeds up magazine reloads and improves tactile engagement while wearing tactical gloves.

• Stable Bipod Mounting Base: Eliminates wobble when mounting standard Picatinny-compatible bipods and foregrips.

• Direct Drop-In Fitment: Precision-manufactured for seamless integration with Tokyo Marui VSR-10 and compatible clone stocks.

Installation & Field Guidance

Installing the PSS kit requires removing the rifle action from the stock using basic hand tools. Unseat the factory front sling swivel stud and original flush magazine button, then align the Laylax housing within the factory mounting channels. Tighten the retaining hardware securely, taking care not to overtighten into synthetic stocks. Apply a micro-drop of silicone lube to the magazine catch pivot pin to ensure ultra-smooth spring return and reliable mag engagement.
