Sig Sauer® 3MOA 1X30mm Reflex Sight - Romeo1 PRO



It's no secret, that Sig Sauer's produced some of the most accurate and reliable handguns in the world. They've managed to push the envelope further by developing one of the most lightweight, compact and capable micro red dots, ever made: The Romeo1 PRO Reflex Sight.

To achieve its incredible size and weight, the Romeo1 PRO uses an aspheric lens: An ultra-thin, multi-curved plane of glass that only needs the smallest housing possible, while still retaining a wide field of view. The red dot sports a 3-MOA reticle for an easy and quick sight picture. Multiple brightness levels are easily adjusted with push buttons, and the entire unit's built with an IPX-7 waterproof rating. Sig Sauer says the Romeo1 is capable of handling .45 ACP recoil and more.

Loads of other features are stuffed into this micro-red dot too: TruHold Lockless Zeroing, utilizing twin adjustment springs that help endure handgun recoil and return to zero with each shot; MOTAC™, Sig Sauer's motion-activated on/off system; SpectraCoat™ and LensArmor™ lens coatings, and Sig's Infinite Guarantee™ lifetime warranty. See below for more info:
