The Helos BTR 1-4.5×24 rifle scope family is specially designed for service rifle matches and AR platforms with short and mid range applications in mind.  The scope is loaded with robust turrets that have 23 MOA travel-per-rotation, true zero stop and revolution locking feature,  and fully multi-coated lenses. The revolution locking feature limits the Up Adjustment of your elevation turret within one revolution from your zero position, while still providing total 23 MOA adjustment that is more than enough for your target at 600 yard. This feature eliminates any second-guessing you might have on which turn you are at on your elevation turret.  The ATSR3 reticle is specially designed for the service rifle matches with the center circle at right size that fits most of your targets and the center dot for precision and horizontal line for wind hold over.

This Helos BTR  Model has ATSR3 second focal plane illuminated MOA reticle in it. Please click the link or download the reticle instruction manual in Specification for more details…



Precision Zero Stop System The system allows you to lock down your zero position and dial back to it with a sharp and precise stop right at your zero mark even you are turning it in pitch-dark or blinded folded.
Revolution Lock The system allows you to lock down your zero position and dial back to it within one rotation turn. It limits the total up adjustment within one rotation to eliminate second-guessing on which turn you have dialed up.
Illuminated Reticle The illuminated reticle provides greater visibility during dusk and dawn and other low ambient light environment.
Etched Glass Reticle Reticle etched on the glass that provides excellent backing support for complex reticle design and offers great durability and much higher shock resistance to recoil
Advanced Fully Multicoated Fully Multicoated optics effectively reduces reflected light and increases the transmission of light giving you a brighter image than normal single coated lenses
6061 T6 Aluminum The 6061T6 aircraft grade aluminum tube that has exceptional strength and superior mechanical integrity will protect these world class optics no matter what punishment you throw at it.
Heat Treated One Piece Tube Construction Heat treated one piece tube gives the scope extra strength over multi-piece tubes. A one piece tube also is better at keeping moisture out thus keeping your scope fog proof for the life of the product
Waterproof Waterproof to protect the scope in the harshest weather conditions or if accidentally submerged underwater
Fog proof Fog proof to allow you to immediately engage your target when you take your rifle to cold ambient temperature from warm inside
Shockproof Robust mechanical system with special designs on both control and erector system that give you the ultimate recoil resistance to withstand 1000G recoil for 1000 times.
Argon Purged Argon Purging uses the inertia gas with bigger size molecules to purge any moisture out of the tube giving you better waterproofing and thermal stability .

    I have been shooting one of these scopes on a NRA/CMP Highpower Service Rifle for a short time and I am impressed. The features on this scope are way above its price point. The 1/4 moa clicks are positive and repeatable and I can click corrections accurately. The numbers on the turrets are big enough for my old eyes. Adjustable parallax allows me to dry fire indoors and I have had it on a .22 upper for 50′ smallbore. The reticle is a real winner for me. The 1/2 MOA dot allows me to favor inside the X ring if needed. The circle “aperture” is usable particularly in offhand. I like the small stadia inside the ring for making sure I am not canting the rifle. I have this on my back rifle now and my primary rifle has a March on it. This scope at this price point is a real winner. It blows my Vortex Viper PST out of the water with 1/4 MOA clicks and parallax adjustment.

    i have used this scope at the recent Talladega match held March 23-24.
    the scope track well, glass is crisp and clicks are solid,
    if the inner circle was just 8 moa it would work better in my opinion, 12 moa is just too big, the 1/2 moa dot works for me really well at 200 and 300 but not at 600, it gets lost.

    I’ve used this scope on my service rifle for about a year now and I think its great The team I am on has pretty much all switched over or is planning on doing so in the future. Clicks are solid and firm. I have not had any issues with it holding its zero. At 600 yds the center dot does get lost but the horizontal ticks and one vertical tick are just right in judging the center at this range. My biggest complaint would be color. The red illumination gets lost in daylight and effectively end up shooting black on black. At maximum brightness there is only a VERY SLIGHT change in shade. If at all possible I would recommend manufacturers to change the color to green or have a switch that can change between red or green for user preference.
