The Leupold Mark 4 MR/T 2.5-8x36 with illuminated Mil Dot reticle and M2 turrets is the correct optic for a Mk12 SPR Mod 0 / Mod 1 clone build. This is the exact scope — same magnification range, same reticle, same illumination, same turret configuration — that Naval Special Warfare and Army SOF designated marksmen ran on documented Mk12 SPRs in Iraq and Afghanistan. Part number 67895 (TS-30 Mod 1 variant).
The MR/T uses Leupold's 30mm main tube for maximum elevation travel, front focal plane reticle (actually, this model is second focal plane — Mil-Dot subtensions are true at 8x), and the M2 external adjustment turrets with 0.25 MOA clicks. The Mil Dot reticle is wire-etched and illuminated for low-light and night-vision use. Matte black finish, argon-purged, waterproof, and built to the Mark 4 standard that has earned Leupold its reputation in military optics.
Mount it on a LaRue LT104 at 1.5" centerline over a Mk12 upper and you've got a textbook SPR. Original Mark 4 MR/T scopes are out of production and the supply is finite.
