The XS Sights GLR201P6N: R3D 2.0 sights are a top-tier choice for anyone seeking a traditional notch and post sighting system. Engineered for high performance, they promise a more luminous, sturdy, and effortlessly installable sighting system to boost your defence readiness. The R3D 2.0 rear is cleverly designed with serrated features to minimize glare, and is equipped with tritium lamps for effective sight alignment regardless of light conditions.The rear sight, with its 0.170 wide notch, aids in improved visibility on either side of the front sight post, promoting swifter sight alignment, particularly in inadequately lit conditions. Following in the footsteps of the original R3D sights, the 2.0 family also incorporates a ledge for simpler one-handed manipulations.In comparison to the original model, the R3D 2.0 sights employ more radiant tritium lamps in the rear sight, guaranteeing visibility in suboptimal lighting circumstances. The black PVC ring that encircles the rear sight lamps further sharpens the edge on the rear sight lamps. This enhances the sight picture while differentiating the front lamp from the rear sight lamps.
