The Holosun ARO EVO SPR Green Dot Sight (ARO-EVO-SPR-GR) is an enclosed-emitter rifle green dot sight with Holosun's Special Purpose Reticle — a 1.5 MOA green centre dot, a 65 MOA circle, three 1 MOA BDC holdovers and a ranging reticle calibrated for M193 5.56 at 3050 FPS — behind a 26 mm (1.02 in) window, weighing 4.33 oz (123 g).
The SPR is what makes this sight unusual. Most non-magnified sights give you an aiming point and nothing else; the SPR adds holdovers and a ranging feature, so a 1x optic can be used past the distance where a plain dot runs out of useful information. The human eye is most sensitive to green, so a green reticle often appears brighter than a red one at the same power setting. Solar Failsafe and Shake Awake back the CR2032, and the 6061-T6 aluminium housing is IPX8 rated and tested to 1000G.
How It Compares
The same sight is offered as the ARO EVO SPR red dot sight and the ARO EVO SPR gold dot sight. If you would rather have a single uncluttered aiming point, the ARO EVO green dot sight is the same housing with a plain 2 MOA dot, and the ARO EVO Dual red dot sight adds an integrated green and IR laser. Browse all enclosed red dot sights, offset red dot sights and straight-pull rifle optics, or read our guide to choosing an optic for an AR-pattern rifle.
Ideal For
- Civilian Service Rifle and practical rifle shooting, where the BDC holdovers extend a 1x sight's useful range
- Practical shotgun and 3-Gun stages, where the 65 MOA circle is quick to pick up
- Night fox and vermin control, where the night-vision settings and Solar Failsafe earn their keep
- Straight-pull AR-pattern carbines in 5.56, which is what the ranging reticle is calibrated around

Frequently Asked Questions
What is the Special Purpose Reticle on the Holosun ARO EVO SPR?
The Special Purpose Reticle combines a 1.5 MOA green centre dot, a 65 MOA circle, three 1 MOA BDC holdover dots below the centre, and a ranging reticle calibrated for M193 5.56 ammunition at 3050 FPS.
What is the ARO EVO SPR ranging reticle calibrated for?
The ranging reticle on the Holosun ARO EVO SPR is calibrated for M193 5.56 at 3050 FPS. Used with any other calibre or load, the holdovers and ranging marks will not correspond to the same distances.
Will the Holosun ARO EVO SPR co-witness with AR-pattern iron sights?
Yes. The Holosun ARO EVO SPR is supplied with both a 1.63 in (41 mm) lower-1/3 co-witness mount and a low mount, so you can co-witness with standard AR-height irons or sit the sight low on a rail.
What battery does the Holosun ARO EVO SPR take and how long does it last?
The Holosun ARO EVO SPR runs on one CR2032 coin cell and is rated for up to 50,000 hours. Solar Failsafe supplements the cell in daylight, and the side-loading battery tray lets you change the cell without taking the sight off the rifle.
Is the Holosun ARO EVO SPR an enclosed green dot sight?
Yes, the Holosun ARO EVO SPR uses a fully enclosed 26 mm window and the 6061-T6 aluminium housing is rated IPX8 for water immersion and tested to 1000G, so mud, rain and debris cannot reach the emitter.
How does the ARO EVO SPR differ from the standard ARO EVO?
The two sights share the same 26 mm enclosed housing, mounts, battery and electronics. The standard ARO EVO has a single 2 MOA dot, while the ARO EVO SPR carries the Special Purpose Reticle with a circle, BDC holdovers and a ranging feature.
