Sig Sauer Romeo MSR Red Dot Sight, 2MOA 1x20mm



Sig Sauer has been known for high quality both for their handguns and for their rifle parts. In keeping with that practice, we bring you the Romeo MSR Red Dot Sight by Sig Sauer. It features a sealed design and has a top-mounted brightness adjustment knob for 10 daytime settings and 2 night vision settings.

The Romeo MSR Red Dot Sight features a parallax-free operation, meaning no matter the angle you look through the glass, wherever you see the dot is where the bullet impact will be. It's also got slipover seethrough flip up lens covers, so you can still use the Romeo MSR while protecting the glass from dust and the elements. The brightness adjustment dial is integrated with the top-loading battery compartment and houses a CR1632. The glass itself is fog-proof, and the Romeo5 is waterproof up to a depth of 1 meter.
