Model ONE S Gen.2 - Custom PCEP Precision Rifle

The Model ONE S Gen.2 represents the solid foundation of the 542 Accuracy vision in the field of precision airsoft. It offers a no-compromise custom experience focused on pure ballistic efficiency in an essential and highly durable configuration.

The beating heart of the replica is the advanced PCEP (Pre-Charged Electro-Pneumatic) system, specifically developed and engineered with a programmable CPU. The innovative hop-up unit with proprietary barrel and bucking is optimized for heavy BBs and extreme long-range precision. The custom chassis, manufactured with modern powder printing techniques and inspired by the Magpul Pro 700 design, offers maximum modularity. The standard stock interface fits M4 Buffer Tubes (with an optional Picatinny adapter available), while the grip utilizes a standard V2 AEG interface.

Exclusive Generation 2 Upgrades

The Model ONE S evolves by integrating top-tier technical updates:

• New Power System: European-made 300-bar air tank (tested to withstand up to 350 bar), easily interchangeable. An optimal fill of 200 bar is recommended, guaranteeing an autonomy of almost 500 shots on a single fill (at 1J power).
• New Regulator: Equipped with an enlarged pre-chamber for flawless shot-to-shot consistency.
• New Barrel & Hop-Up: Updated internal geometries for the barrel, hop-up system, and TDC tensioner.
• Updated Electronics: New CPU engine firmware update.

S Version Equipment

The Model ONE S version is designed for the straightforward shooter, offering:

• Aluminum Outer Barrel: A robust and clean design solution that ensures excellent torsional rigidity and high reliability in any environment.
• Essential M4 Stock: Mounted on a standard Buffer Tube interface, without a cheek rest to maintain a slim profile and manageable weight.
• Standard Trigger Unit: Responsive and reliable, perfect for managing shooting dynamics with the PCEP system.
• Custom 90° Grip: Ensures superior control and stability. It conveniently houses the Allen key used for micro-adjusting the PCEP pressure (allowing you to easily stay within legal limits based on BB weight).
