Best red dot rifle sight
This is the best red dot rifle sight. Mount does not come loose like the QD ones. Love the circle dot reticle. very light weight and rugged.

So far so good. Nice optic.
I am using Romeo4DR optics on my rifle caliber pistols, and got this for my primary Carbine. I wanted the solar power backup and the increased water resistance of this version while retaining the same reticle. I like the hex nut clamps as opposed to the Torx on the $DR as it is easier to torque properly and service in the field if necessary. The only complaint I have is that the manual does not address the removal of the flip up covers to use the optional cover and flashkill device. Additionally, i would prefer the marking for which direction to turn the windage an elevation adjustment to actually be on the adjusters as opposed to being laser etched in the body of the optic. The next generation should have tethered caps for the battery and adjusters.

You will want either this or the Romeo 4T
Very pleased with this product. Comes with everything you need and nothing you don't. Love the motion sensing technology and supplemental solar power. You are typically limited by either battery life or constantly switching a sight on and off, but this system turns it on when you pick it up and shuts it down after it hasn't been moved for a couple of minutes. Always ready without worrying about dead batteries. Low profile enough to stay out of the way and rugged enough to perform under abuse. Worth every penny.

Fake or broken

An iron site user is converted.
Don't get me wrong, its spendy. But it will turn an average shooter into an outstanding shooter with minimal practice. Worth the money. Very durable. Very happy with this optic. Variety of red dot sight pictures is a huge up, but I've always kept it on the circle & dot (eotech from what I understand).
