Why Choose the Rapax 2+J Sniper Spring?

• 2+ Joule performance in standard sniper setups
• Easier bolt pull while achieving higher FPS than conventional springs
• 13mm outer diameter for broad sniper rifle compatibility
• Reduced spring "twang" for a quieter firing cycle
• Consistent power delivery
• Premium spring wire for increased durability
• Special tempering process helps minimise FPS/Joule loss over time
• Compatible with popular aftermarket heavy pistons

Power & Performance

Actual power depends on your rifle's barrel length and internal setup.

Typical performance:

• Approx. 1.9J with a 300mm barrel
• Up to approx. 2.8J with the longest barrel configurations
• Approx. 450–500 FPS with 0.20g BBs using standard barrel lengths

Always chronograph your rifle after installation, as different barrel lengths, air volumes, pistons, hop setups and air seals can significantly affect muzzle energy.

Compatible Airsoft Sniper Rifles

The Rapax 2+J Airsoft Sniper Spring is compatible with:

• Silverback TAC-41
• Silverback SRS
• Novritsch SSG10
• Novritsch SSG96
• Novritsch SSG24
• Modify Scout
• Many other compatible sniper rifle platforms using a 13mm OD spring

It is also an excellent fit for aftermarket heavy pistons including:

• Stalker Scorpion
• W.A.S.P. Piston
• EDGI pistons

This makes the Rapax 2+J an excellent choice when building or upgrading a TAC-41 sniper rifle, SRS sniper rifle or other high-performance airsoft sniper platform.

Getting the Best Performance

For accurate power measurements, adjust your hop-up using the heavyweight BBs you actually intend to use rather than relying solely on readings taken with 0.20g BBs.

Correct hop adjustment provides a more realistic indication of your rifle's Joule output and actual field performance.

For smooth operation, apply lithium grease or another suitable thick grease to the spring and spring guide. This can also help reduce spring noise and wear.

Adjustable Power

Need to reduce your rifle's power?

The Rapax 2+J spring can be shortened by carefully cutting coils, allowing the output to be tuned for your specific rifle setup.

Make adjustments gradually and chronograph the rifle after each change.

Built for Long-Term Performance

Rapax springs are manufactured from premium-grade spring wire and undergo a specialised tempering process designed to provide excellent durability with minimal power loss over time.

The result is a high-performance airsoft sniper upgrade spring that combines strong power output with a smoother bolt pull and dependable consistency.

Important

The Rapax 2+J does not guarantee a specific Joule output. Depending on your rifle configuration, output can range from approximately 1.9J to 2.8J.

Always chronograph your airsoft sniper rifle after installation and ensure it complies with your site's power limits before use.
