When the shot is inside 300 yards and speed matters more than magnification, a low-power variable with a clean reticle and reliable zero is the right tool. The Athlon Helos BTR 1-4.5×24 delivers that with a precision zero stop, revolution lock, and the ATSR3 illuminated reticle featuring a 12 MOA service-rifle-match circle — built for fast acquisition without the complexity of a high-magnification optic.

The ATSR3 is a second focal plane reticle with an illuminated 12 MOA center circle sized to frame targets used in most service rifle matches, plus a 0.5 MOA center dot for precise aiming. Hash marks at 2 MOA intervals provide windage holdovers when needed. Subtensions are accurate at the maximum 4.5× magnification. At 1×, the illuminated circle works like a red dot for fast, both-eyes-open shooting.

Key Features

• 30mm one-piece tube with 80 MOA elevation and windage travel — sufficient adjustment range for most short and mid-range applications
• Precision zero stop with revolution lock — the zero stop provides a hard return to your confirmed zero, while the revolution lock prevents the turret from spinning past the intended revolution
• 100 ft field of view at 1× — wide enough for both-eyes-open shooting and fast target transitions in close quarters
• Advanced fully multi-coated optics with XPL coating — AFMC lenses deliver high light transmission, critical for a compact 24mm objective
• Argon purged — inert gas purging provides superior fog-proofing and internal moisture resistance
• Side focus parallax adjustment — adjustable from 10 yards to infinity, uncommon on a low-power variable and useful for precision work at known distances

Ideal For

Service rifle and CMP competitors who need a low-power optic with a reticle circle sized for standard match targets — the 12 MOA illuminated circle frames the target naturally at speed.

AR-platform and home defense builds where fast target acquisition at close range is the priority — the true 1× low end with illuminated circle provides red-dot speed with the option to reach out to 4.5× when needed.

Hunters in thick cover who take most shots inside 200 yards and want a lightweight, fast-handling optic with a reliable zero — the zero stop and revolution lock ensure the scope stays dialed where you set it.
