Sightmark Ultra Shot A-Spec Reflex Sight 1x33x24, Multi-Reticle Red, Matte Finish, Picatinny Mount
Sightmark
The Sightmark Ultra Shot R-Spec reflex sight is a versatile, non-magnified optic built for shooters who value flexibility and durability. Whether you're running a defensive rifle, sport shooting setup, or hunting platform, this 1x33x24 reflex sight delivers a wide, unobstructed field of view with four switchable reticle patterns—5 MOA dot, 3 MOA dot with 50 MOA circle, 3 MOA dot with 50 MOA crosshair, or 3 MOA dot with 30 MOA circle/crosshair—so you can dial in the subtension that matches your shooting style and distance. The dual red/green reticle options (10 brightness levels each) make it easy to pick up your sight picture in any light, from dim indoor ranges to bright outdoor hunts.
Built from aluminum 6061-T6 in matte black, this reflex sight is built to handle hard use. The anti-reflective, scratch-resistant lens coating protects your glass while maintaining sight picture clarity. The parallax correction system (set at 25 yards) keeps your point of aim true across a broad range of distances. Windage and elevation both offer 120 MOA of adjustment range in 1 MOA clicks, giving you room to zero and re-zero on different firearms or after an optic change. The Interlock internal locking system holds your adjustments where you set them. Rated for .50 BMG recoil, this sight won't flinch on anything in your safe.
On a single CR123A battery, you'll get between 200 and 2000 hours of runtime depending on your brightness setting—meaning you can keep it running bright at the range or dial down and stretch battery life for overlanding or backup use. The package includes the sight, a quick-detach Picatinny mount, adjustment tools, battery, and a protective neoprene cover, so you're ready to mount and shoot out of the box.

You get four switchable patterns: a 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 30 MOA circle/crosshair. Each reticle is available in red or green, and brightness is fully adjustable across 10 levels plus off, so you can tune your sight picture for any lighting condition.
The Ultra Shot R-Spec carries an IP55 water-resistance rating, meaning it's protected against water spray and brief submersion. It's suitable for wet weather and water crossings in the field, though it is not fully waterproof. The matte black aluminum body and AR-coated lens are also built for durability against scratches and weathering.
The package includes the reflex sight, a quick-detach Picatinny mount, adjustment tools, a CR123A battery, and a protective neoprene cover.
A single CR123A battery will deliver between 200 and 2000 hours of runtime, depending on the brightness setting you use. Lower brightness levels extend battery life significantly, making this sight practical for extended field use or backup roles where you're not constantly running maximum brightness.
