Man, a question I might know something about
First, I have tons of hours behind the ReapIR it’s a beast and taken tons of hard use without issue. The key points on ReapIR are its small and lite weight for a thermal scope (works great as a scanner also) , great high end construction/feel, it’s simple to use and the joy stick is faster with custom presets(Nuc/zoom/etc) vs MK III and clarity is awesome.
The MK III 60mm plus I’ve owned a MK I and MK II 35mm in the past for reference. Once again the MK III housing is first rate feels like a Nightforce scope construction quality wise high end all the way, menu knobs are great and easy to use however I wish there was a quick one way NUC button vs having to go back to menu, the 60mm lens provides a awesome picture at longer ranges. MK III is a beast when it comes to overall performance.
Now if I could only have one? Right now it would have to be the ReapIR the size and weight is just freaking awesome and the 2.5X mag meets 90% of my shooting needs. I also think the menu and joy stick is faster to use in the field. I preset my four most used settings for the quick set menu so within 2 seconds I can Nuc/zoom/take a pic with ease.
This takes nothing away from the MK III 60mm it’s a incredible weapon sight and flat out will provide a better image at longer ranges. I just find most all my shooting occurs under 100 yards and the bigger FOV of the ReapIR works better at closer range or up in timber/woods. The weight and size is also a big factor I walked 4 miles of trail last night carrying the MK III 60mm and I felt the weight end of hunt. The MK III is my long range setup that said shots at 50 yards it works fine.
