Solink M130 High Power Spring

Want to push your AEG past the outdoor cap into DMR territory? The Solink M130 spring is what you drop in when 330 FPS stops being enough and you need to clear 425, 450, or even 500 on a chrono.

What the M130 rating means. Spring weights are lettered M90 through M140+, and the number is a rough guide to velocity in an otherwise standard setup. An M100 lands around 320–330 FPS on 0.20g BBs, so the M130 puts you squarely in semi-only DMR range. Rated 420–500 FPS on 0.20g, which clears most outdoor AEG caps and reaches into bolt-action territory at the top end. Your actual number depends on cylinder volume, barrel length, air seal quality, and BB weight, so chrono with your own load before game day.

Fits every gearbox. This spring works with all Version 2, 3, 6, and 7 AEG gearboxes. Stainless steel construction throughout, which resists the metal fatigue that kills lower-quality springs after extended runs.

Before you buy. An M130 is a heavy spring. It raises stress everywhere: your gears, piston, motor, and wiring all feel it. Pair it with a high-torque motor and CNC steel gears, and make sure your air seal is solid—a leaking piston head O-ring wastes all that extra compression. On a stock gearbox with stock internals, you’re asking it to pull weight the components weren’t designed for. A well-shimmed box with a sorbothane pad on the cylinder head is also smart—the impact on a non-firing cycle is the everyday cause of a cracked shell.

This is a spring only. Spring guide, piston, and all other internals are sold separately.
