Most Popular Firearm Springs
Constant Force Springs
Constant Force Springs provide consistent force, for each round, from first to last. Offering higher force in a compact space, constant force springs make for smoother reloads than traditional compression magazine springs, allowing for easier use of higher capacity magazines.
Power Springs
Power Springs are used in drum and rotary style magazines for high capacity, reducing the need for reload. They provide high-cycle life and quality material for superior and constant performance.
Wire Forms
Wire Form Springs are available with a wire size capability of .008”-.177”, which aid in retention locking applications.
