THE best sub $800 optic in existence
The Aimpoint T2 set the standard, but the Sig Romeo 4T Pro meets the T2 and even exceeds it in some ways for a lot less money. The original 4T series had been thoroughly tested in real world military and law enforcement applications and the feedback from those professionals was used to create the 4T Pro series. Improved caps, a kill flash, relocation of the buttons, removal of the solar feature, and the addition of a common-use lithium battery are just some of those improvements. The mount is very solid and can be swapped for any quality micro mount. The glass is very clear, the reticle bright and sharp, and the battery life is simply amazing. I have been using 4T's on duty for years, so when I first got my hands on the 4T Pro I was not expecting much of an upgrade. I was wrong. As good as the 4T is the Pro is even better. If you are looking at the T2 save yourself a bunch of money and get the 4T Pro. If you are looking at the Aimpoint RDS (or HS515) buy yourself a much better red dot for just a few dollars more.

Best bang for buck
Amazing duty-level red dot. Performance is excellent. Amazing battery life and I love that it uses AAA batteries. Great light transmission under night vision. Only thing I don't like is that the windage adjustments on my unit don't have very positive adjustments/clicks and is a bit mushy. The elevation adjustment does not have this problem. For the price, this optic easily beats out aimpoint, as it also comes with mounting options, scope caps, and an ARD

Excellent Red Dot
This red dot is truly great. It has great NV performance, battery life and built so rugged. I love the fact that you can switch up the reticles to what you want and they are very clear. Keep in mind that if you have an astigmatism it won’t look crisp but that has more to do with your personal eyes not the red dot. It’s priced above the cheaper red dots but below the upper tier in price but not quality or capability.

Great optic
Bought this optic after many hours of research on my first build. Great optic, took it to the range in 20 degree weather for 8 hours and it held up great, no regrets on this purchase.

Sold as new but this had to be some else’s defective return - I’ve been swindled
Bought this product as new in good faith, it was well over $500. On receipt all Packaging was intact, including the holographic SigSauer sticker on the seam of the lid. However, inside box was a disaster: the red-dot sight’s battery compartment was almost welded shut from what looks like a battery leak! How would this be possible for a new product?! Compartment was coated with the effluence that one typically gets from leaky batteries, the threads for the cap are corroded… who knows what else - May waterproofing was impacted. Wasn’t my fault I’ve had this piece of crap for only a few hours. this is either a return to SigSauer that made it into packaging as new, or somebody else in the supply chain tried to repurpose a return. I will be whole again (financially) once the return is processed but a lot of inconvenience. Printing return labels, purchasing a replacement, not using my rifle in interim…. Be warned. This was my first purchase from Sig (Romeo and Juliet) for almost $1K. Might well be my last based on this experience.
