The Steiner 3-12x50 Military/Tactical Riflescope model 5312 is made for outstanding flexibility. This scope is perfect for both the long range shooter and close range tactical shooter. You can accomplish everything from a long range sniper shot to an urban, “in your face”, combat situation. The 50mm objective makes the Steiner 3-12x50 riflescope very bright in a manageable 34mm tube size. This model lends itself to mounting very well on AR platform rifles. Like all Steiner military/tactical scopes the shooter can adjust the parallax without taking their eyes off the scope. The Steiner 3-12x50 military riflescope provides up to 5 mil of windage adjustment on each side, and up to 19 mil of elevation adjustment, with audible click adjustment knobs that give precise 0.1 mRAD/click adjustments. The reticle is a G2 Mil-Dot illuminated reticle which can be tuned from very dim to very bright very easily. All Steiner Military/Tactical riflescopes come with Butler Creek ocular and objective covers and are fully submersible waterproof , shockproof and nitrogen purged fog proof.
