Athlon Optics Cronus BTR GEN2 UHD 4.5-29×56 APLR5 FFP IR MOA

The Athlon Cronus BTR GEN2 UHD 4.5-29×56 APLR5 FFP IR MOA is Athlon's flagship long-range scope, pairing UHD extra-low-dispersion glass and a 34mm tube with 110 MOA of elevation travel, an illuminated FFP reticle, stainless steel turret internals, and a precision zero stop — delivering the optical clarity and mechanical precision that serious competition and long-range hunting demand. The Cronus sits at the top of Athlon's lineup, using premium glass and coatings that deliver noticeably sharper, brighter, more color-accurate images than the Ares and Midas lines below it. Independent reviewers consistently rank the Cronus GEN2 UHD among the best scopes in its price class for resolution and chromatic correction.

Key Features

• UHD extra-low-dispersion glass with advanced fully multi-coated lenses and XPL protective coating delivers bright, color-true images with minimal chromatic aberration — the UHD glass uses extra-low-dispersion elements that virtually eliminate color fringing, even when glassing high-contrast edges at max magnification. Reviewers describe the image quality as competitive with scopes costing significantly more
• 110 MOA total elevation and 64 MOA total windage adjustment in a 34mm tube with 25 MOA per revolution — the 34mm tube provides the internal space for generous adjustment range, giving you the travel to dial confidently past 1,000 yards on virtually any centerfire cartridge without a canted rail
• Exposed elevation and windage turrets with stainless steel internal components produce sharp, loud, tactile clicks that are easy to count and track. The stainless internals resist wear and maintain consistent feel over thousands of adjustments — a premium feature that sets the Cronus apart from scopes with softer alloy turret mechanisms
• Precision zero stop returns to your exact zero with a hard, repeatable stop — essential for dialing back after long-range engagements
• 0.25 MOA clicks with tracking that independent testers have verified as dead-on through the full adjustment range
• First focal plane APLR5 MOA illuminated reticle — etched glass with MOA-based holdover references that stay accurate at every magnification. The illumination provides visibility in low-light conditions at dawn and dusk, and can be turned off entirely for daytime use
• 4.5-29x magnification range with a 56mm objective — 29x gives you the resolution to read mirage, spot splash, and identify targets at extreme distance, while the 56mm objective gathers enough light to maintain a bright, usable image across the power range. The 4.5x low end provides a wide enough field of view for target acquisition and situational awareness
• Side-focus parallax adjustment from 25 yards to infinity — handles everything from mid-range precision work to extreme distance
• 34mm one-piece aircraft-grade aluminum tube, argon-purged and sealed — waterproof, fogproof, and shockproof

Ideal For

PRS and NRL competitors who want flagship-grade glass and mechanical precision — 110 MOA of elevation travel, a zero stop, stainless steel turret internals, and crisp 0.25 MOA clicks deliver the mechanical features that top-level competition demands. The UHD glass gives you an edge in target identification and mirage reading that cheaper optics cannot match. At 35.8 oz in a 34mm tube, this is a purpose-built competition optic.

Long-range precision shooters building around 6.5 Creedmoor, .308 Winchester, 6.5 PRC, or magnum cartridges who want the best glass Athlon makes — the 34mm tube and 110 MOA of elevation put confident dialups to 1,000+ yards within reach, and the UHD glass lets you read conditions and correct at distance with clarity that competes with scopes at twice the price.

MOA-system shooters who prefer quarter-minute clicks and MOA-based holdovers — the 0.25 MOA clicks and APLR5 MOA FFP reticle keep your turrets and reticle in the same language, and the 25 MOA per revolution makes tracking your position on the elevation dial straightforward.

Western big-game hunters who glass at distance and need to make precise shots across canyons — the 4.5x low end handles close encounters in timber, while 29x lets you evaluate trophy quality and read wind at 500+ yards. The illuminated reticle extends your shooting window into the low-light conditions that bookend every hunting day, and the zero stop ensures you can dial for a long shot and return to your hunting zero instantly.
