Like potato chips...you can't just have one...

I now have 3 of these Romeo 5's and will keep buying them for budget builds. These little red dots are so sweet. The motion activated reticle pops on when the gun moves. This allows for extending the battery life. I typically get 3 to 6 months per battery, which are common and easy to find. The reticle is crisp and these little gems hold their zero perfectly. I have never had any issues with that, nor any problems with battery contacts. The Romeo is notoriously tough, a google search will reveal severe testing done on these without failure. Negatives are mainly that the turrets are not covered but it hasn't been a problem for me. Comes with low and high mounts and they will also work with any Aimpoint TI mounts are these are basically clones. The Romeo has acquired a reputation as a tough as nails performer, and I have found that to be the case as well.
