Important notes before you buy

• QD connector not included - please select either QD EU 4mm or QD US 4mmadaptor.
• SSG-10 compatibility: for SSG-10 builds, the stock trigger must be replacedwith a standard VSR-10 type trigger.

How it works (simple, effective design)

SDiK is essentially a gas cylinder unit that cycles when you operate the bolt. When you load the rifle, the unit moves back, fills with air, then delivers a measured burst of air directly into the hop-up chamber when you pull the trigger - resulting in stable output and consistent performance.

Key features

• Quick, drop-in installation SDiK installs in place of the piston inside the cylinder. Route the air line through the trigger box, connect to your regulator, and you're ready to go.

• Extremely consistent FPS When assembled correctly, SDiK can achieve under 1 FPS spread between shots for excellent repeatability.

• Easy bolt operation / light "spring feel" The unit is returned forward by a soft spring (around M100 AEG spring equivalent), keeping the action smooth and easy to cycle.

• Wide, precise power adjustment Tune output from very low power up to around 650 FPS by adjusting regulator pressure - ideal for matching site limits or building for specific roles.

• No electronics Fully mechanical operation - no batteries, no wiring, no weather-related electronic issues.

• Upgrade-friendly You don't need to change your trigger, cylinder, or hop-up to run SDiK, but it remains compatible with many popular tuning parts if you decide to upgrade later.
