Strike Industries Modular Magazine Release Kit for AR-15/LR-308 - Black

Fine-tune your AR-15 or LR-308 magazine controls with the Strike Industries Modular Magazine Release Kit for AR-15/LR-308. This drop-in kit solves a common shooter frustration: one-size-fits-all mag buttons that don't match your hand size, grip angle, or operational preference. Instead of swapping out the entire magazine catch assembly, you get three interchangeable button options—Standard, Extended, and Oversized—so you can dial in the ergonomics that work best for your rifle and shooting style, whether you're running drills at the range or in the field.

The kit ships complete and ready to go. You'll find all three textured polymer buttons, a steel magazine catch, the magazine spring, and the stainless steel shaft sleeve and adapter needed for a true drop-in installation. The real genius is the modular design: swap button styles without removing the mag catch. A simple push and a small object—a round or even a pen—lets you swap buttons in seconds. This is ideal for shooters who run multiple setups or want to experiment without gunsmithing.

Build quality reflects Strike Industries' reputation for no-nonsense AR parts. The buttons pair lightweight polymer with a SUS630 stainless steel shaft sleeve for durability and corrosion resistance. The textured surface gives you confident thumb placement under stress or in cold/wet conditions. Whether you favor a low-profile Standard button, need the reach of an Extended option, or prefer the palm-friendly Oversized profile, this kit covers you—and lets you change your mind at the next range session.
