Pushing a precision rifle to 1,000 yards in PRS-style matches or long-range steel challenges demands an optic with enough magnification to spot impacts, enough elevation travel to dial the distance, and repeatable turrets you can trust round after round. The Athlon Ares BTR GEN3 HD 4.5-27x50 delivers 27x magnification and a precision zero stop with HD glass in the same 27.3-ounce chassis as its close-range sibling.

Key Features

• HD low-dispersion glass with advanced fully multi-coated lenses and XPL protective coating delivers bright, color-true images with reduced chromatic aberration — the Gen3 glass represents a meaningful upgrade over the Gen2 platform
• 80 MOA total elevation and windage adjustment in a 30mm tube, with 25 MOA per revolution for predictable tracking — enough to dial confidently past 1,000 yards on most centerfire cartridges without a canted rail
• Precision zero stop returns to your exact zero with a hard, repeatable stop — no counting clicks back from an arbitrary reference point
• 0.25 MOA clicks are loud, distinct, and free of slop or lash — the Gen3 stainless steel turret redesign is wider, shorter-profile, and delivers the best tactile feedback in Athlon's lineup
• First focal plane APLR13 MOA reticle with illuminated center — hash marks at consistent MOA increments with a fine floating center dot that provides a precise aiming point without obscuring the target. Subtensions are accurate at every magnification
• 4.5-27x magnification range with a 6x zoom ratio — the 4.5x low end keeps you usable for moderate-range shots, while 27x gives you the resolution to read mirage, spot splash, and make precise corrections at extended distance
• Side-focus parallax adjustment from 25 yards to infinity covers the full range of centerfire precision shooting distances
• 30mm one-piece aircraft-grade aluminum tube, argon-purged and sealed — waterproof, fogproof, and shockproof
• Gen3 upgrades include redesigned stainless steel turrets, integrated throw lever, threaded sunshade, and threaded metal lens caps with magnetic closures

Ideal For

PRS and NRL competitors — 80 MOA of elevation travel, a zero stop, and Gen3 turrets give you the dial-and-shoot confidence that stage-to-stage precision rifle competition demands. At 27.3 oz in a 30mm tube, this scope keeps your rifle light enough for positional stages while delivering the magnification and tracking you need at distance.

Long-range precision shooters building around 6.5 Creedmoor, .308 Winchester, 6.5 PRC, or similar cartridges — the 4.5-27x range and 80 MOA of elevation put your first-round hits at 800-1,200 yards well within reach. The HD glass and FFP reticle let you read conditions and correct without lifting your head from the stock.

Budget-conscious tactical shooters who want FFP, zero stop, and quality turrets without spending $1,200+ — the BTR GEN3 delivers the core feature set of the Vortex Viper PST Gen II 5-25x50 at a lighter weight with a wider low-end magnification range, and includes the throw lever, sunshade, and magnetic metal caps that competitors sell as accessories.

Hunters who want more magnification than the 2.5-15x50 for western open-country hunting where shots at 600+ yards are realistic — the 27x top end lets you positively identify game and read wind at distances where the 15x model starts to fall short, while the 4.5x low end still gives you enough field of view for closer encounters.
