EOTech 518-2 Holographic Weapon Sight (EOT-518-2)

If you want the “runs on AAs” convenience without giving up the side-button layout and quick-detach mount people love on the EXPS-style footprint, the 518-2 is the lane. It’s built for speed up close, but the reticle gives you extra aiming references when you add a magnifier.

What you’re getting with the 518-2

• AA-powered optic: uses two AA batteries (supports lithium, alkaline, or rechargeable).
• Side buttons: easier control access when running the optic close to a magnifier.
• Locking quick-detach mount: fits 1" Weaver and MIL-STD-1913 (Picatinny) rails.
• Duty-ready build: water resistant to 10 ft (3 m) and designed for hard use.

Reticle: 68 MOA ring with two 1 MOA dots

The 518-2 “two-dot” reticle keeps the big speed ring for fast indexing, then adds two 1 MOA dots so you can use additional aiming references, especially when magnified. Many listings describe these as ballistic dots or a two-dot reticle.

Magnifier and Laser Battery Cap compatibility

The 518 line is commonly paired with a magnifier, and the side-button layout helps keep things compact on the rail. The 518-2 is also frequently listed as compatible with EOTech drop-in Laser Battery Caps (LBC) designed for visible and IR aiming options.

Who this optic is perfect for

• Home defense / duty setups: fast reticle acquisition with a rugged housing.
• Rifles that live on AA logistics: if you already stock AAs, it’s a simple win.
• Magnifier users: side buttons + two-dot reticle are a solid combo when you’re switching between 1x and magnified.
