Magazine Upgrade

Sure Cycle magazine upgrades greatly improve the capabilities of the stock magazine tube on your shotgun. These kits include vital mag tube upgrade components for a number of makes and models of shotguns.

Each kit comes with a replacement stainless steel magazine spring at the appropriate length for your shotgun which provide both corrosion resistance and strong tension strength. Both a model specific red anodized aluminum low-drag follower and 3 shot plug are also included.

Sure Cycle offers individual followers as well when you want the high performance / visibility of an aftermarket follower but have no use of a plug or new spring.
