Athlon Optics Helos BTR GEN2 2-12×42 AHMR2 FFP IR MIL

Most LPVO-class scopes force a choice: fast acquisition at close range or usable holdovers at distance. The Athlon Helos BTR GEN2 2-12×42 bridges that gap with the AHMR2 FFP reticle — a 4 MIL illuminated center circle with a 0.3 MIL dot for precision, plus an integrated ranging reticle calibrated for deer-sized targets out to 600 yards.

The AHMR2 reticle pairs a wide center circle for fast target pickup at 2× with a fine 0.3 MIL center dot that becomes a precision aiming point as magnification increases. Below center, the Christmas-tree holdover grid extends to 8 MIL with windage dots that progressively widen at each drop line. A built-in distance ranging ladder — calibrated for an 18-inch target (whitetail buck) — gives rapid range estimation from 200 to 600 yards without a rangefinder. First focal plane keeps all subtensions accurate across the full 2-12× range.

Key Features

• 30mm one-piece tube with 32 MIL elevation travel — generous adjustment range with 25 MIL of windage and 10 MIL per revolution for fast dialing
• Locking turrets with precision zero stop — pull up to dial, push down to lock. The zero stop returns you to your confirmed zero with a hard, repeatable stop
• 55.7 ft field of view at 2× — wide enough for both-eyes-open shooting and fast target transitions at close range, narrowing to 9.6 ft at 12× for mid-range precision
• Advanced fully multi-coated optics with XPL coating — AFMC lenses deliver high light transmission across the spectrum, while the XPL protective layer guards against abrasion and environmental damage
• Argon purged — inert gas purging provides superior fog-proofing and internal moisture resistance compared to nitrogen-filled alternatives
• Side focus parallax adjustment — adjustable from 10 yards to infinity for parallax-free shooting at any distance

Ideal For

Hunters running one rifle from timber to treeline who need a scope that covers 50-yard brush shots and 400-yard cross-canyon opportunities with a single optic — the 2× low end and illuminated center circle handle close-range speed, while FFP holdovers stay accurate for longer pokes.

3-gun and multi-gun competitors who want FFP MIL holdovers in a lightweight 25.4 oz package — the wide field of view at low magnification handles close bays, while 12× provides enough reach for precision stages.

DMR and designated marksman builds where the rifle needs to function from CQB distances out to 600 yards — the integrated ranging reticle gives rapid distance estimation on deer-sized targets without breaking position to use a rangefinder.
