Leupold Mark 4 TS30-A2 2.5-8x36mm — TMR Reticle Illuminated, Mk12 SPR Scope
SOCOM selected the Leupold Mark 4 TS30-A2 for the Mk12 SPR program for a clear reason: it works. This is the optic that sat atop Mk12 Mod 0 and Mod 1 rifles in the hands of Army Rangers and Navy SEALs performing the designated marksman role in Afghanistan, Iraq, and across multiple theaters. The 2.5x to 8x magnification range gives you the flexibility to engage targets from close quarters out to the extended distances where the Mk12's 18" precision barrel earns its keep. For a clone-correct Mk12 build, this scope is not an option — it is the specification.
TMR Reticle: Built for Ranging and Holdover
The Tactical Milling Reticle (TMR) was designed specifically for the ranging and holdover work that designated marksman operations demand. Mil-based stadia lines allow the shooter to estimate target range using known target dimensions — a fundamental skill for precision shooting at unknown distances. The holdover marks provide reference points for applying ballistic corrections without adjusting the turrets between shots. In operational scenarios where a designated marksman may engage multiple targets at different ranges in rapid succession, a reticle that facilitates quick holdover application is a genuine capability advantage.
Illumination for Low-Light Operations
The illuminated reticle keeps the scope operational in low-light environments — dawn, dusk, and the overcast conditions that reduce available light in operational theaters. SOCOM operations do not stop when lighting conditions degrade; the equipment cannot either. Leupold's illumination system on the Mark 4 series is designed for the reliability demands of military use, not simply for commercial appeal.
