The SHS M100 AEG spring (TH1023) is a non-linear spring rated as an M100 / SP100 equivalent. It is a common choice for refreshing or tuning a standard AEG.
The spring is made from high-tensile tempered steel with ground flat ends, which help it seat squarely in the gearbox. It fits V2, V3, V6 and V7 gearboxes.

UK Legal & Site Notes
Springs are internal parts, not imitation firearms, so no defence is needed. A new spring changes your power, so chrono the rifle with your usual BB weight and check it against your site’s limits before you play.
