Optical Design
The S-TAC 1-4.5x24 SR1 Service Rifle Scope is the ultimate tool for competitive shooters that demand the very best optical technology. Designed and engineered for Civilian Marksmanship Program’s Service Rifle and NRA High Power Rifle competition use, the S-TAC 1-4.5x24 SR1 utilizes Sightron custom optical glass with exclusive MC-333 lens multi-coatings. This combination provides exceptional light transmission all while reducing flare so the shooter can easily acquire their target.
Reticle Design
The SR1 reticle provides a clean sight picture with a 9 MOA circle surrounding a ½ MOA aiming dot. One MOA stadia lines on the horizontal and lower vertical areas help draw the eye to the center of the reticle.
Multicoating Technology
SIGHTRON’s exclusive MC-333 multi-coating technology applies premium camera grade multi-coatings throughout the optical design for the best possible light transmission, contrast, and clarity for dramatically reduced color fringing, flare, and chromatic aberrations even in the harshest lighting conditions.
ExacTrack Accuracy
Never experience reticle drift again. SIGHTRON utilizes their exclusive ExacTrack erector tube system to deliver consistent, reliable, and repeatable adjustments even at the extreme edges of the scope's adjustments. This means 1/4 MOA click values are the same at 30 MOA up as they are at zero.
Scope Construction
The 30mm tube design is crafted from premium-grade aluminum, is shock-rated to 1,000G’s for more than 10k cycles. It meets IPX7 waterproof standards, is nitrogen charged to prevent fogging of the interior glass elements even when moving from a warm car to sub-zero temps.
