March Scopes March-F Tactical 1-10x24mm LPVO 30mm Tube Rifle Scope w/Custom Unimount First Focal Plane DR-TR1FB Reticle Black D10SV24FDIML-P-DR-TR1FB. The technical and assembly challenges with respect to dual reticles are extreme and they are pushing the limits of the state of the art in reticle design. The tolerances required in assembly of the DR-1 are such that very few are able to do it especially with a 10X zoom ratio. Any deviation from these extremely tight tolerances will be visible in the 10X zoom range. The assembly of this scope like all March Scopes other offerings is meticulous. This is want they are known for: superb assembly of extremely strong fine works of art.
