Battle Arms Development Bad-Eps-Al-Red Bad Alumn Takedown Pins Red
Battle Arms Development takedown pins in red anodized aluminum offer a straightforward way to personalize your AR-15 lower receiver while keeping functionality front and center. These CNC-machined pins are built to mil-spec tolerances, fitting all standard AR-15, M16, and M4 lower receivers with .250-diameter pivot and takedown pin holes. Whether you're assembling a new build, refreshing an existing rifle, or just tired of looking at plain steel hardware, red anodized aluminum pins deliver a clean aesthetic without compromise.
What sets Battle Arms Development's Enhanced Pin Set apart from basic mil-spec hardware is the engineering behind the details. The low-profile pin heads sit flush and won't snag or catch during assembly, disassembly, or carry—a real advantage over taller aftermarket alternatives. The ambidextrous safety-compatible design ensures smooth operation with any standard safety selector, and the bullet-tip guide eases installation and helps prevent cross-threading or damage to your lower receiver's takedown pin holes.
Battle Arms Development has been designing and manufacturing AR components since 2009, focusing on incremental improvements that shooters actually notice. These pins are a perfect example: they're not revolutionary, but they're thoughtfully engineered and finished to a standard you won't find in bargain bins. Red anodized aluminum resists corrosion and looks sharp on any build—whether you're running a tactical carbine, a precision rifle, or a hunting AR.
