Sig Sauer Romeo MSR Gen II Compact 1x20mm 2 MOA Red Dot Sight - M1913

The Sig Sauer Romeo MSR Gen II is a compact red dot sight purpose-built for modern sporting rifles and other long-gun platforms. Designed and assembled by Sig Sauer Electro-Optics, the Gen II update refines the proven Romeo MSR with refreshed electronics, a longer battery life, and the same lightweight, rugged housing that made the original a popular choice for AR-platform carbines.

At the core of the optic is a parallax-free 2 MOA red dot reticle projected through a 1x20mm objective window. The dot is powered by a side-loading CR2032 battery that delivers up to 35,000 hours of runtime, and brightness is controlled via a rotary illumination dial offering 12 settings - 10 daylight levels plus 2 night-vision compatible settings. The result is a crisp aiming point that stays visible from full sun to low light.

The Romeo MSR Gen II ships with a low-profile M1913 Picatinny mount, providing a secure, see-through co-witness with standard AR-height iron sights and direct attachment to most flattop rails. IPX-7 waterproof and fog-proof sealing ensures the optic holds zero through rain, mud, and brief submersion. At just 2.7" long and weighing approximately 5.7 oz, the compact housing keeps your rifle's sight picture uncluttered and its balance point forward.

Whether you're running a home-defense carbine, a 3-Gun competition AR, or a hunting rifle in matte black rifle-friendly trim, the Romeo MSR Gen II offers Sig Sauer electro-optic quality and a familiar, user-friendly feature set at an accessible price.
