The Athlon Ares BTR Gen3 HD 2.5-15×50 FFP Riflescope (Athlon part no. 212015J) pairs a wide-range zoom with a first focal plane, illuminated APRS13 MIL reticle. HD glass and advanced fully multi-coated lenses push more light and sharper detail to your eye, and a precision zero stop lets you return to your starting zero after dialing. The 30mm tube and exposed turrets suit a long-range hunting or PRS-style rifle that gets dialed often. Because the reticle sits in the first focal plane, its MIL subtensions stay true at every power setting.

Key Specifications

• Magnification runs 2.5-15x, a range that covers close targets and distant shots with one scope.
• The objective lens is 50mm, which gathers light for dawn and dusk shooting.
• The main tube is 30mm, giving generous internal travel for elevation and windage adjustment.
• The reticle is the APRS13 MIL in the first focal plane with illumination, so holdovers stay accurate at any magnification.
• Turret clicks are 0.1 MIL on exposed turrets, with 10 MIL per rotation and 29 MIL of total travel in both elevation and windage.
• A precision zero stop returns the elevation turret to your original zero.
• Eye relief is 3.9 inches, which keeps the eyepiece comfortable under recoil.

Frequently Asked Questions

Is the reticle in the first or second focal plane? It is in the first focal plane, so the APRS13 MIL reticle scales with magnification and its holdover marks stay valid across the zoom range.

What are the turret adjustments? Turrets click in 0.1 MIL increments with 10 MIL per rotation. Total elevation and windage travel is 29 MIL each, and the scope has side focus parallax adjustment starting at 10 yards.

What is the tube size? The tube is 30mm, so use 30mm rings or a 30mm one-piece mount.
