Springs

The spring puts pressure on the piston, and is responable for the compression of air to the bb.

Some springs are measured in Percentages. these are based on the standard Tokyo Marui springs, which are at 280 FPS (100%). The Modify SP Springs are equal to the M designation (SP100 = M100)

These values are estimates! Maintenance and parts are very influential!
