Handmade Rapax springs: manufactured in Europe to provide the best and quietest performance for your sniper airsoft replica, such as SRS / VSR / SSG24.

Confirmed results of reaching 3+ Joules with a standard SRS. FPS may vary depending on the configuration used in SRS, SSG24, or VSR-10.

Results:

• The 3+ spring delivers between 3J (G-Spec) and 3.8J for longer SRS inner barrels.
• The Hulk spring delivers between 3.5J (G-Spec) and 4.9J for longer SRS inner barrels.
• The 2+ spring delivers between 2.3J (G-Spec) and 3J for longer SRS inner barrels

If the Rapax spring shoots too hot for your field limits, you can cut a few coils without damaging the integrity of the spring, as long as it is done correctly.

The first thing you will notice is a lighter pull compared to standard springs — in short: less effort for more joules. The Silverback M160 spring and the Rapax 3+ J require similar pulling force, but the Rapax 3+ J spring delivers more FPS / joules in comparison.

All springs have the same length, use the same material, and have the same number of coils, etc.
The spring wire used in the production of Rapax springs is of the highest quality, ensuring a longer service life compared to other springs.

The tempering process of these springs is carried out to ensure long lifespan and very minimal FPS / joule loss over time.

The springs are manufactured with strict diameter tolerances, preventing the "twang" sound in sniper airsoft replicas.
