The TacFire MAR090R is an AR15 rear takedown pin with ring, machined from black steel for reliable field stripping and reassembly. If you're building, maintaining, or replacing wear parts on an AR platform rifle, a quality takedown pin is one of those small details that matters—it needs to be durable enough to handle repeated disassembly without stripping or bending, and simple enough that it works every time you need it. This pin is designed to do exactly that.
Takedown pins are easy to overlook until you need them, but they're critical to how your AR functions. A worn or damaged rear pin can make field stripping frustrating, introduce binding or wobble during assembly, or worse, compromise the integrity of your receiver. The TacFire MAR090R gives you a straightforward replacement or upgrade option with the durability of steel and a ring design that makes handling intuitive, whether you're doing maintenance on a range day or in the field.
This is the kind of part you don't think much about until you own a firearm that doesn't have one—then it becomes obvious how much smoother your workflow is with a solid takedown pin. Black steel construction stands up to regular use, and the ring configuration is a time-tested design that keeps your pin secure and easy to manage during disassembly.
