The Athlon Helos BTR with a street price just under $400, is the most affordable LPVO that offers a side-focus parallax focus. Most LPVO’s (even Service Grade LPVOs over $2K) only offer 100-150yrds fixed focus optics. This Helos BTR was designed with the input of NRA High Power XTC “service rifle” class competition shooters.
The first sample that Athlon sent me had a very minor 1x image shift issue that most shooters would never notice unless you ran it with both eyes open. I’ve discovered image shift at 1x to be a common issue with LPVOs; I’ve even experienced this in much vaunted combat grade LPVOs from Trijicon and Vortex. I contacted Athlon, who’s excellent customer service got me a replacement quickly.
My first impression of the Helos is that of an optic in a higher price tier in terms of build and construction. It has exposed turrets are similar to high-precision turrest found on Athlon’s long range optics. The elevation turret has a one revolution zero-stop for competition. For an AR moving from the 200yrd to 600yrd target during a XTC competition, the adjustment for drop would be within it’s 23MOA rotation. Its beefier turrets also help make it a tad heavy at around 23oz.
The reticle ATSR3 SFP reticle is unique to this Athlon model offering a crosshair-with-floating dot within its circle of death. The center circle and holdover T are illuminated for day-to-dusk competitions but is not red-dot bright. Against black competition bullseyes, a brighter illumination would be welcome.
When I first got the Helos BTR, I was puzzled as to its relatively low 1-4.5x power range, which I assume comes from the heritage of NRA High Power ‘service rifle’ competitions. The current marketing trend in LPVOs to offer more-is-better with 8x, 10x, and higher magnification. I wonder why Athlon doesn’t offer a parallax focus in their 1-10 Ares ETR? Regardless, the Helos BTR is an LPVO that offers competition grade features and high quality optics at a “budget” price for an Athlon.
