Rapax HULK Sniper Rifle Spring, APS 13mm - 4J+

The Rapax HULK High Velocity spring is the most powerful spring in the Rapax lineup, designed for players who want maximum muzzle energy and extreme range from their sniper rifles.
Like all Rapax springs, the HULK is handmade in the EU from hardened spring steel and features a progressive coil design for slightly smoother cocking. However, make no mistake – this is an extremely strong and demanding spring, placing heavy stress on both the user and the rifle’s internals.

It delivers very high power levels and is recommended only for experienced players with rifles upgraded with reinforced internals. Perfect for sniper platforms such as SRS, TAC-41, VSR-10 and more.
