Most Popular Gun Springs Used for Firearms
Constant Force Springs
Constant Force Springs provide continuous force from your firearm’s first round to the 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 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.
Torsion springs offer precision and accuracy to trigger and hammer mechanisms. They are also used in dust covers and flip-up sights.
We offer compression springs which can be used in a variety of applications such as detent mechanisms, buffer tube assemblies, AR style lower and upper receiver springs, sights, trigger spring assemblies, ejector springs and mounts.
Wire Form Springs are available with a wire size capability of .008”-.177”, which aid in retention locking applications.
