Rapax springs comparison

Rapax spring comparation. Rapax 2+J Rapax 3+J and Rapax Hulk springs on test

Comparison of Rapax springs, including Rapax 2+J, 3+J, and Hulk springs, was conducted during testing. Your personal results may vary depending on your setup, particularly the length of your inner barrel and the piston used in your rifle. Testing your rifle’s performance with Rapax light pull springs is a recommended method, as Rapax 2+, 3+, and Hulk springs maintain a consistent strength across batches. You can always expect to achieve the same fps/J as others if your setup is optimal.
