Vortex Diamondback Rifle Scope 2-7x35mm Rimfire V-Plex Reticle (MOA), 1" Tube

From Vortex:
TThe Diamondback—loaded with features! First, the solid one-piece aircraft-grade aluminum alloy construction makes the Diamondback riflescope virtually indestructible and highly resistant to magnum recoil. Argon purging puts waterproof and fogproof performance on the agenda, and advanced fully multi-coated optics raise an eyebrow when crystal clear, tack-sharp images appear in the crosshairs. Look for all this and more in a riflescope you'd expect to cost quite a bit more-but doesn't. We can live with that.
2-7x35 Diamondback Rimfire has a 50-yard parallax setting which makes it ideal for use at close range on 22 rimfire, shotguns and muzzleloaders.
V-Plex reticle is the single best all-purpose hunting reticle intended for a wide variety of hunting applications.
Parallax is set at 50 yards.
