Rapax 3J+ Light Pull Airsoft Sniper Spring

High-Power Easy Pull Sniper Spring for TAC-41, SRS, SSG10 and Precision Builds

If you’re building a serious long-range sniper rifle, consistency and smooth operation matter just as much as raw power. The Rapax 3J+ Light Pull Sniper Spring is designed for players who want increased Joule output and higher FPS without the heavy, punishing bolt pull often associated with high-power sniper springs.

Using Rapax’s renowned progressive spring design, this upgrade delivers smoother cocking action, quieter operation, and more efficient energy transfer while maintaining the power needed for advanced sniper and DMR builds.

Compatible with many of the most popular sniper platforms including the Silverback TAC-41, Silverback SRS, and Novritsch SSG10, the Rapax 3J+ spring is trusted by players looking to maximise long-range consistency without sacrificing usability during extended gameplay.

Why Choose the Rapax 3J+ Light Pull Spring?

• High-power 3J+ performance with smoother bolt pull
• Designed for long-range sniper and DMR builds
• Reduced spring “twang” for quieter operation
• Compatible with major sniper platforms and aftermarket pistons
• Built from premium tempered spring wire for long-term durability

Built for High-Power Precision Setups

Traditional high-power sniper springs often create harsh cocking resistance and excessive fatigue during gameplay. The Rapax Light Pull Spring is engineered to deliver:

• Increased Joule output
• More controlled compression
• Smoother bolt cycling
• Reduced strain during cocking
• More stable shot consistency

For sniper players spending hours behind the rifle during milsim events or woodland skirmishes, this creates a far more manageable and enjoyable shooting experience.

The quieter shot cycle also helps reduce the metallic spring resonance commonly found in standard sniper springs.

Compatible Sniper Platforms

The Rapax 3J+ Spring is compatible with many popular sniper rifle platforms including:

• Silverback TAC-41
• Silverback SRS
• Novritsch SSG10
• Modify Scout
• VSR-compatible sniper rifles
• Other common 13mm spring setups with 9mm guides

It also works particularly well with aftermarket heavy pistons including:

• Stalker Scorpion
• Sniper Mechanics WASP
• EdGi piston systems

Rapax 3J+ vs Standard Sniper Springs

Different sniper spring designs create very different shooting characteristics.

For experienced sniper players, the Rapax 3J+ Light Pull Spring offers an excellent balance between power, consistency, and usability.

Expected Performance

Performance depends heavily on:

• Barrel length
• Air seal quality
• Piston weight
• Hop setup
• BB weight selection

Typical outputs include:

• Approx. 2.8J on shorter G-Spec builds
• Around 3.4J on standard 420mm barrel setups
• 520+ FPS with 0.20g BBs on longer barrel configurations

Always chrono your rifle correctly and ensure compliance with your site’s limits and joule rules.

Installation and Tuning Tips

For best performance:

• Pair with heavyweight sniper BBs
• Properly lubricate spring and guide using lithium grease
• Fine-tune hop-up for heavier BB weights
• Combine with quality air seal and piston upgrades

The spring can also be trimmed carefully if lower FPS tuning is required for site compliance.
