Element - Upgrade Oil Temper Irregular Pitch Spring M165ST (520-600fps)- IN0110

The Element M165 AEG spring is an irregular pitch spring. The non-linear pitch of the spring makes it easier to compress the spring for installation and reduces stress on the piston during pick up by the sector gear. Note: The "M" rating of a spring is often related to a general velocity rating imparted by the spring, in this case, "165" notes 165 meters per second, which converts to ~540 FPS, depending on gearbox factors, such as gear stroking and compression efficiency.
