bought a Reap Ir. Haven’t had a chance to hunt with it yet. Just played around the house with it a little to get used to the menus. One thing I noticed is that the shuttered eye cup they send with the unit is a nice idea. However when I mounted it on my AR it’s impractical. I have to tilt the rifle at an angle just so my eye can activate the rubber piece so I can see though the darn thing. I figure it’s better off just taking it off for hunting. Are all thermals eye reliefs like this?
