Athlon Optics Midas Beam TSR1 Red Dot Sight

A bigger window means faster target acquisition — and the Midas Beam has the largest window in Athlon's pistol red dot lineup. The 32x24mm lens with an RMR footprint gives you the widest possible field of view for picking up the dot on presentation, while the included picatinny mount makes it equally at home on an AR, shotgun, or PCC. Same 50,000 hours of battery life and motion-sensor wake as the Burst, in a platform that crosses over from pistol to long gun.

The motion-activated sleep mode puts the Beam to rest after 5 minutes of inactivity and wakes it the instant it detects movement — the dot is live when you need it without burning through the CR2032 sitting idle. Ten brightness settings cover indoor to full-sun conditions, and Athlon built the chassis from aircraft-grade aluminum in a one-piece, nitrogen-purged design that's waterproof, fog-proof, and shockproof. Windage and elevation turrets adjust at 1 MOA per click.

At 1.95 oz and 1.77 inches, the Beam adds minimal weight whether it's riding a slide or sitting on a riser. The 0.68" center height (without mount) keeps the profile low on a pistol slide, while the included picatinny mount options provide 0.90" (low) or 1.57" (high) center heights for rifle and shotgun setups.

Key Features

• 32x24mm window — the largest lens in Athlon's Midas red dot line for the fastest dot acquisition on presentation
• 50,000 hours battery life — over 5 years of constant-on runtime at medium brightness
• Motion-activated sleep/wake — sleeps after 5 minutes of inactivity, wakes instantly when movement is detected
• 3 MOA red dot — balances fast acquisition with defensive precision
• RMR footprint + included picatinny mount — mounts directly to RMR-cut pistol slides or to any picatinny rail for rifle, shotgun, and PCC use
• Fully multi-coated lens — maximizes light transmission for a bright, crisp dot
• Aircraft-grade aluminum chassis — nitrogen purged, waterproof, fog-proof, and shockproof at just 1.95 oz

Ideal For

Pistol shooters who want a larger window — the 32x24mm lens makes picking up the dot faster on the draw compared to smaller micro dots, especially for shooters still building the muscle memory for dot presentation.

Multi-platform setups — the RMR footprint handles the pistol, and the included picatinny mount moves the same optic to an AR, shotgun, or PCC without buying a separate sight.

Competition and home defense where 50,000 hours of battery life and motion-wake mean the optic is always ready — mount it, zero it, and trust it.

Compatibility

RMR-style footprint mounts directly to slides milled for Trijicon RMR or compatible adapter plates. The included picatinny mount provides two height options: low mount (0.90" center height) for co-witness setups, or high mount (1.57" center height) for comfortable heads-up shooting on rifles and shotguns.
