Rapax 2.8J Airsoft Sniper Spring

Please note that the stated FPS is higher than UK site limits - these high-power springs are designed to be used in conjunction with sound dampers, which reduce the overall noise produced by a sniper's spring at the cost of FPS output, allowing for maximum performance to be maintained. 

Wide Compatibility

The Rapax 2.8J spring is made for seamless integration with popular sniper replicas, including:

• Silverback SRS & TAC41
• Novritsch SSG10, SSG24 and SSG96
• Modify sniper models

Easy Adjustment with Spacer

If you still have room for extra performance, simply use the included 4mm power-up spacer to gain more power.

Proven Durability

Crafted in Europe from the highest-quality spring wire, the Rapax 2.8J spring:

✔ Delivers over 10,000 shots without losing power.
✔ Features an electroplated finish for rust resistance and reduced friction, giving you smoother performance and longer spring lifespan.

Optimized for 2.8 Joule Limit (with 0.48g BBs)

The Rapax 2.8 J spring has been tested with heavy BBs in:

• Silverback SRS, Tac41 spring (16″ barrel)

🔹 Note: Joule output may vary based on barrel length, piston weight, and hop-up settings.

Ready for 2.8J Airsoft Sniper Field Limit
