<p>There are large window RMR Optics, and then there’s the Omega red dot sight. Featuring a huge lens window and competition-ready features, the Omega is designed to speed up target acquisition and improve accuracy without costing you an arm and a leg. We’ve engineered the features you need, like a dual-MOA circle/dot reticle, adjustable brightness, and a long battery life that’s extended by our innovative low-power mode with shake-to-awake technology, then matched that engineering to materials that are ready for the rigors of field use in dynamic tactical situations. Shoot better with an extra-large window dot sight from a company you can count on to have your six.</p> <p><strong>Big Sight Picture, Small Groups</strong><br />The large lens on the Omega red dot sight gives you a big sight picture without blocking out your field of view–always dangerous in a duty or defensive tactical situation. This makes it the perfect pistol optic choice for shooting competitions, range work, as a duty weapon, or as a backup reflex sight on larger firearms.</p> <ul> <li>The 7075-T6 aluminum housing is made from the same material often used in components for the m-16 rifle and other firearms.
