Fantastic optic! by Dan, March 4, 2019
Overall I love this optic! I’ve had several Eotechs and trijicon MRO optics and found that for the price this optic is just as good with better features and lower price point! In addition, it’s not as bulky and offers two reticles!

I prefer the Leopold pro red dot reticle and the features on the sig Romeo 3. The look of the 3 is also more flush than the 4. That being said it is on one of my favorite rifles the Blackrain socom 458.
