If you’re looking for budget‑friendly electro‑optics, the AT3 Tactical RD50 reflex sight is an ideal choice that combines essential features at a low cost. A durable, machined‑aluminum build, a precise 2 MOA dot and an easy brightness control make the AT3 reflex a great match for both AR‑15 sport rifles and hunting rifles. This version comes with a .83" high mount.

The AT3 Tactical RD50 offers the user:

• Excellent target visibility and quick target acquisition
• A low‑profile, universal form factor suitable for many long‑gun platforms
• Natural, both‑eyes‑open aiming for maximum shooting dynamics
• A precise 2 MOA dot with multi‑step brightness adjustment via a convenient knob
• Unlimited eye relief, allowing use on a wide range of firearms
• Advanced lens coatings that reduce glare and increase light transmission
• A mount dedicated for AR‑15 rifles enabling an absolute cowitness setup

The housing is made from anodized aluminum, ensuring low weight and high durability. Inside sits a simple optical system that provides true 1× magnification, so two‑eye aiming is comfortable and natural. The low profile of the body does not significantly restrict the field of view and makes it easy to track targets.

The 2 MOA dot allows precise aiming even at longer distances. The sight offers easy zeroing thanks to marked adjustment drums and a positive click. Parallax is eliminated to ensure accuracy, while unlimited eye relief means the sight can be used in any shooting position on virtually any firearm. With the .83"‑high mount you can achieve an absolute cowitness with A2‑height iron sights on most rifles.
