The Athlon Helos BTR Gen2 1-10×28 ATMR4 SFP IR MOA riflescope (Athlon part no. 214103) is a second focal plane option for shooters who want a low-power variable at an affordable price. Athlon says it lets you assess and engage silhouette-sized targets out to 700 yards with 68 or 69 grain .223/5.56 NATO cartridges. The ATMR4 reticle is illuminated and calibrated in MOA, and a 34mm tube sits under a true 1x low end. Advanced fully multi-coated lenses and XPL coating protect the glass, and the optic is sealed and gas purged to stay waterproof. For an AR-style carbine that needs speed up close and some reach, this Athlon scope is a practical choice.

Key Specifications

• Magnification is 1-10x, a true 1x low end with enough power for longer shots.
• The objective lens is 28 mm, which keeps the scope slim and light on the rifle.
• The main tube is 34 mm, which suits 34mm rings and gives generous adjustment travel.
• Focal plane is second focal plane (SFP), so the reticle stays the same apparent size as you zoom.
• The reticle is the illuminated ATMR4 MOA design, which stays easy to pick up in low light.
• Turret clicks are 0.5 MOA, a coarser value suited to carbine-style shooting.
• Eye relief is 3.2 inches, which suits quick shouldering on a carbine.
• The field of view is 110 feet at 1x down to 10 feet at 10x at 100 yards, a wide view at the low end.
• The scope is 10.3 inches long, a compact length for a carbine.
• The scope weighs 18.3 oz, light enough to keep a carbine quick to handle.
