This Helos BTR 1-4.5×24 rifle scope family is specially designed for service rifle matches and AR platform for short and mid range applications. The scope is loaded with beefy 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.

Features:

- 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
- 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
