Non-linear spring for AEG replicas - M100 to M150 - UNICORN AIRSOFT

The UNICORN AIRSOFT brand offers this steel propulsion spring for AEG replicas, which features an irregular (non-linear) coil design that optimizes compression consistency. Available in 6 power levels, from M100 to M150, it allows you to precisely adjust your replica's power according to its intended use: for example, an M100 spring is suitable for CQB, while an M150 provides more power and is therefore better suited for long-range configurations such as sniper setups.
