The spring directly affects the total power output of the rifle in conjunction with air seal components. Low-quality springs may initially offer high power, but they often lose tension quickly, shorten, or even break under stress—especially if stored under tension. The POWER SPRING by Action Army is designed to deliver maximum power consistency in your bolt-action sniper rifle. Made from high-quality spring steel, it offers excellent durability and resistance to fatigue. We recommend combining it with other upgrade components by Action Army.
Consider your physical strength when selecting a spring. Stronger springs like M170+ can be extremely hard to pull back.
