Vortex Diamondback Tactical 4-12x40 SFP VMR-1 MOA Rifle Scope
Built for shooters who want tactical-style precision in a streamlined package, the Vortex Diamondback Tactical 4-12x40 SFP VMR-1 MOA Rifle Scope delivers reliable performance without unnecessary complexity. Its 4-12x magnification range is ideal for mid-range shooting and hunting, offering a perfect balance between field of view and target detail. The VMR-1 MOA reticle provides clean, effective holdover and windage references, while the second focal plane design keeps the reticle consistent and easy to read. Exposed tactical turrets with zero-reset allow fast, repeatable adjustments, and the fibre optic rotation indicator gives a clear visual cue of turret position. With XD glass, fully multi-coated lenses, and a rugged 1-inch aluminium tube, this scope is built to perform in real-world conditions with dependable accuracy.
