Review: Step up your shooting game - Like other Sig products, this red dot is clear and accurate.
Review: 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
*by L***M on December 21, 2024*

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
