Built for serious long-range shooting, the Crimson Trace 5 Series 3-18x50mm Tactical Rifle Scope CTL-5318 combines premium Japanese ED glass, a First Focal Plane MR1-MIL illuminated reticle, and exposed tactical turrets in a rugged 34mm platform designed for hunting and precision shooting applications.
Unlike many optics in this price range, the CTL-5318 features premium Japanese ED glass for outstanding clarity, sharp edge-to-edge image quality, and improved low-light performance. The result is a bright, crisp sight picture with excellent colour contrast and target definition across the full magnification range.
The glass-etched MR1-MIL illuminated reticle sits in the First Focal Plane, allowing accurate holdovers and ranging at any magnification. Combined with precise 0.1 MIL exposed turrets, zero stop functionality, and a forgiving eyebox, this scope is equally at home on a long-range hunting rifle or precision range setup.
Constructed from a single-piece 6061-T6 aircraft-grade aluminium tube, the CTL-5318 is waterproof, fogproof, nitrogen purged, and built to handle demanding field conditions.
