2.8J Performance with Heavyweight BBs

The Rapax 2.8J spring has been tested using 0.48g heavyweight BBs in platforms including:

• Silverback SRS
• Silverback TAC-41 with 16-inch barrel
• Novritsch SSG10 with 430mm barrel

Actual Joule output will vary depending on barrel length, piston weight, air seal, hop-up adjustment and overall rifle configuration.

Always chronograph your rifle using the BB weight you intend to play with.

4mm Power-Up Spacer Included

If your rifle is producing less power than required and the setup allows additional adjustment, the included 4mm spacer can be used to increase spring preload and power.

This provides additional flexibility when tuning the spring to a particular sniper build.

Adjustable Power

If the spring produces more energy than required, coils can be carefully trimmed to reduce power without compromising the spring's integrity.

Make adjustments gradually and chronograph the rifle after each modification.

Premium Construction & Durability

Rapax 2.8J springs are manufactured in Europe using high-quality spring wire and feature an electroplated finish designed to improve corrosion resistance and reduce friction.

The spring is designed to deliver more than 10,000 shots without losing power, providing dependable performance for frequently used airsoft sniper rifles.

Installation & Tuning

For the most accurate results:

• Use heavyweight BBs when measuring Joule output
• Set your hop-up for the correct flight path before chronograph testing
• Apply suitable lithium or thick grease to the spring and spring guide
• Chronograph after installation and after making adjustments

Correct lubrication can also help reduce the characteristic spring "twang" produced by high-powered sniper setups.

Important UK Power Information

The Rapax 2.8J is capable of producing energy above typical UK airsoft site limits.

Sound-dampening components and other internal modifications can alter the final power output, but they should not be relied upon to guarantee compliance. The finished rifle must always be chronographed and remain within the applicable legal and individual airsoft site's energy limits.

For players building a precisely tuned TAC-41, SRS, SSG10 or other high-performance airsoft sniper rifle, the Rapax 2.8J provides a durable, adjustable high-power spring with excellent platform compatibility.
