Sightmark Ultra Shot A-Spec Reflex Sight 1x33x24, Multi-Reticle Red, Matte Finish, Picatinny Mount

The Sightmark Ultra Shot A-Spec reflex sight is a versatile 1x33x24 red dot designed for shooters who need a fast, no-magnification sight on rifles, shotguns, and carbines. This is a working optic built for hunters, sport shooters, and defensive rifle users—not a precision long-range tool, but a point-and-shoot solution that keeps both eyes open and lets you track moving targets or engage multiple threats without slowing down. The matte-black aluminum body handles hard use, and the Picatinny mount goes on any modern rifle, carbine, or tactical shotgun.

What sets the Ultra Shot A-Spec apart is its multi-reticle flexibility: four selectable red patterns (a clean 5 MOA dot, a 3 MOA dot with 50 MOA circle, a 3 MOA dot with 50 MOA crosshair, and a 3 MOA dot with a 30 MOA circle/crosshair combo) let you dial in the sight picture that matches your shooting style and intended distance. Ten brightness levels plus dedicated night vision modes mean you're covered in dim conditions or on night-vision gear, and the auto-off feature stretches battery life to as much as 2000 hours on a CR123A cell. The sight is parallax-corrected at 10 yards, so your point of aim stays true across a reasonable range of head position—important in a fast-shooting scenario.

Build quality is solid: the aluminum 6061-T6 housing is shock-proof to 8 feet, the AR-coated lens resists scratches, and recoil handling is rated all the way up to .338 (and beyond, if you're running .50 BMG). The sight is water-resistant to IP55, so rain and splashes won't kill it. Elevation and windage both adjust across 120 MOA in 1 MOA clicks, giving you the flexibility to zero for different distances or ammunition. The quick-detach mount lets you swap it off when needed, and compatibility with the XT-3 magnifier means you can add magnification without replacing the entire sight.

This is a honest, no-frills reflex sight: parallax-corrected for close to mid-range work, reliable in the field, and affordable enough not to break the bank on your next build or upgrade.

Frequently Asked Questions

Will the Ultra Shot A-Spec work with a magnifier?

Yes. The Ultra Shot A-Spec is compatible with the XT-3 magnifier, which you can attach behind the reflex sight to add magnification when needed without replacing the sight itself.

What battery does it use, and how long does it last?

The sight runs on a single CR123A 3V battery. Battery life ranges from 200 to 2000 hours depending on which brightness setting you use. The auto-off feature helps extend runtime, and a low-battery indicator alerts you when power is getting low.

Is this sight weatherproof?

The Ultra Shot A-Spec has an IP55 water-resistance rating, which means it can handle rain, splashes, and wet conditions. It is not fully submersible, but it will perform reliably in typical field and hunting weather.

What reticles are included?

The sight offers four selectable red reticle patterns: a 5 MOA dot, a 3 MOA dot with a 50 MOA circle, a 3 MOA dot with a 50 MOA crosshair, and a 3 MOA dot with a 30 MOA circle/crosshair. You can switch between them to suit your shooting scenario.
