NcStar ATRLS Tri-Rail Universal Barrel Mount 5mW Red Laser

The NcStar ATRLS is a compact 5mW red laser sight built around a tri-rail universal barrel mount that clamps onto most standard rifle barrel diameters without requiring any modification to the host firearm's rail system. The integrated tri-rail provides three Picatinny surfaces for stacking additional accessories, lights, or grips right at the front end of the rifle.

The laser delivers 5mW of red light at a 635-655nM wavelength, producing a clean 1mm aiming dot for fast target acquisition. A simple side-to-side on/off toggle switch keeps operation intuitive, and the unit is powered by two included AG13/LR44 button-cell batteries for a no-tools-needed install. The body is constructed from aircraft-quality anodized aluminum with a black anodized finish for corrosion resistance, paired with high-impact polymer components to keep total weight down to just 2.80 oz.

Installation is straightforward: the over-barrel clamp secures the laser and its tri-rail around a standard barrel, making the ATRLS a versatile aiming and accessory-platform solution for rifles that lack a top rail or need a forward-mounted aiming reference. Whether running a classic sporting rifle or a modern defensive carbine, this NcStar unit gives you a dependable red aiming point and a hard-mounting platform in a single lightweight package.
