As compared to the RMRs bottom-mount battery, the SRO’s battery is accessed from the top and does not require sight removal to access, nor does it need a battery sealing plate. Life of the CR2032 battery is three years when left on setting four.

Most dots are “sparkly” to me, but the SRO was better. The glass is visibly clearer, and the dot crisper compared to the HRS and the DPP. You feel like you are looking through a pistol mounted MRO with a wider field of view and less of the frame blocking your view. Using a round shape makes it natural for the eye to pick up. The auto brightness setting worked fine for me moving from inside to outside and back. Just like the RMR, you can use manual control as needed. It still co-witnesses suppressor sights but barely.  Each sight set is a bit different and mounts on 1911s seemed to work best. 

Bottom Line

Less or no tube effect, less occlusion, wider field of view and easier to see dot were the takeaways compared to the RMR. Changing the battery from the top is huge, as is losing those annoying sealing plates. If you already have a Type 2 RMR or an HRS you may not want to make the swap, but if you are still looking, you really need to look at the SRO first—it really is better. Maybe not a game changer for some, but better. The SRO should be at the top of anyone’s list, but especially for concealed carry and duty applications.

The 2.5-MOA dot proved quick and also allowed for precision shots at 50-plus yards. The internals of the SRO are designed to last 30,000 rounds, the sight is waterproof and submersible to 10-feet. Overall, it’s a measureable improvement over the company’s previous benchmark-optic, the RMR.
