The Holosun ARO EVO SPR, part number ARO-EVO-SPR-RD, is an enclosed-emitter 1x rifle sight carrying Holosun's Special Purpose Reticle behind a 26 mm (1.02 in) window.
Most non-magnified sights give you an aiming point and stop there. The SPR adds 1 MOA holdovers below the dot and a ranging feature, so a 1x optic keeps telling you something useful past the distance where a bare dot runs out of information.
The reticle combines a 1.5 MOA red centre dot, a 65 MOA circle, 1 MOA holdovers and a ranging reticle calibrated around M193 5.56 at 3050 FPS. Illumination has 12 settings, 8 for daylight and 4 compatible with night vision, adjustment is 0.5 MOA per click across ±50 MOA, and a CR2032 in a side-loading tray is rated for up to 50,000 hours with Solar Failsafe and Shake Awake behind it. The housing is 6061-T6 aluminium, IPX8 rated, tested to 1000G and weighs 4.33 oz (123 g).
Both a 1.63 in lower 1/3 mount and a 1.05 in low mount come in the box, along with auto-brightness and a lockout mode that stops the settings being nudged in a case. The honest caveat is the calibration: the ranging marks and holdovers were worked out for M193 5.56 at 3050 FPS, so with another calibre or a different load they no longer correspond to the distances printed against them.
Both mounts supplied fit a MIL-STD-1913 Picatinny rail: the 1.63 in mount co-witnesses with standard AR-height irons, the 1.05 in mount sits the sight low. If the ranging reticle is more than you want, the ARO EVO with a plain 2 MOA dot is the same housing simplified; the same SPR reticle in green is the ARO EVO SPR green, and the ARO EVO Dual adds an integrated green and IR laser.
