Our Billet Aluminum High Vis Low-drag Follower & Enhanced Safety replaces the factory plastic & steel components, with our CNC machined profile just like the factory profile for 100% direct fit. The main feature of our Enhanced Safety is the custom CNC design. Implementing curved ridges help guide your finger naturally and more securely, which leads up to our extended stop for extra surface area when releasing. This overall design is more comfortable to use, more secure, and more durable than the stock oem plastic piece. The Follower offers high visibility for quick assessment of the magazine tube for added safety. The aluminum material will not rust or corrode & therefore will last for years of use.
