iRay USA ACE-H50: The ACE is compatible with bolt action or semi-automatic rifles using standard 30 mm mounts and rings. The combination of an internal USB-C charging battery and a removable 18650 style rechargeable battery allows users to hot-swap batteries in the field to run indefinitely. A 1-3x ocular magnifier provides optical magnification of the 2560x2560 round Amoled display inside the eyepiece. The Vision+ system pairs this high-resolution display with a 15 mK Netd sensor for an incredibly detailed and precise image.
