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



Sig Sauer's one of those big names when it comes to accurate and high-quality firearms. That also holds true for their surprisingly affordable red dots, like the Romeo MSR Red Dot Sight. It's built from a tough, one-piece aluminum housing. The optic's also fully sealed, it's waterproof, and it has a brightness knob mounted right on top with 10 daytime and 2 night vision settings.

The Romeo MSR Red Dot Sight will improve your accuracy with ease. The red dot is parallax-free, so no matter the angle you look through the glass, wherever you see the dot is where the bullet will impact. It's lens covers are see-through, so you can still use the Romeo MSR while protecting the lenses from dust and debris. The top-loading battery compartment houses a CR1632 battery, providing up to 20,000 hours of life. For all this, the Romeo MSR only weighs 4.9 ounces - less than half a pound.
