KONUS SULTAN 1-10×24 LPVO Rifle ScopeBuy the KONUS SULTAN 1-10×24 and experience the ultimate versatility in a single optical platform designed for the modern tactical shooter and hunter. This revolutionary scope combines true 1× magnification with an impressive 10× zoom range, delivering unmatched adaptability for engagements from close-quarters to extended distances. Built around a robust 30mm tube with an exclusive ballistic reticle system, the SULTAN represents exceptional value in the competitive LPVO market.Performance Engineering & FeaturesThe SULTAN's incomparably versatile 10× zoom system sets it apart in the crowded LPVO market. Unlike many scopes that compromise optical clarity across their magnification range, the SULTAN delivers genuine 1× performance for rapid target acquisition in close-quarters scenarios while extending to 10× for precision work at extended distances. This extraordinary zoom ratio provides tactical versatility that covers virtually any shooting scenario.Built on a 30mm one-piece aluminum tube, the SULTAN provides enhanced structural integrity and increased internal adjustment range compared to standard 25.4mm designs. The scope features an engraved and illuminated ballistic circle reticle that combines rapid target acquisition with precision holdover capabilities. Zero-stop tactical turrets allow shooters to make precise 1/4 MOA adjustments while maintaining the ability to return instantly to their established zero.Advanced Construction Features:Fully multi-coated optics for maximum light transmission and contrast24mm objective lens optimizing balance between light-gathering and compact profileWaterproof, shockproof, and fogproof with nitrogen purging for extreme conditionsRemovable zoom lever for rapid magnification changesFlip-up covers protecting lenses during transportTechnical Specification KONUS SULTAN 1-10×24SpecificationDetailMagnification1-10×Objective Lens24mmTube Diameter30mmReticleEngraved, Illuminated Ballistic CircleTurretsTactical with Zero-Stop FunctionClick Value1/4 MOAConstructionOne-piece aluminum, nitrogen-purgedWaterproof Rating100% waterproof, fog-proof, shockproofIncluded AccessoriesFlip-up covers, removable zoom leverVersus Other Konus ModelsThe SULTAN represents a significant evolution beyond traditional KONUSPRO hunting scopes. While KONUSPRO models focus on ballistic holdover reticles for specific applications, the SULTAN's 1-10× range and tactical features position it as a true multi-role optic. Compared to T30 3-12×44 models, the SULTAN offers the critical advantage of true 1× magnification for close-quarters work, while the KONUSPRO-IMPACT series typically maxes out at 9× with 25.4mm tubes.Expert Applications & Answers (FAQ)Q: How does the SULTAN's 1-10× range compare to traditional 1-6× LPVOs for tactical applications?A: The SULTAN's extended 10× capability provides significant advantages for target identification and precision engagement beyond 400 meters, while maintaining the same close-quarters performance as traditional 1-6× scopes. This eliminates the need for separate optics for different engagement distances.Q: What makes the 30mm tube specifically beneficial for the SULTAN's wide magnification range?A: The 30mm tube provides approximately 25% more internal adjustment range, crucial for accommodating the wide magnification range while maintaining tracking accuracy. It also allows for larger internal lens elements, improving light transmission and optical quality across the zoom range.Q: How does the ballistic circle reticle enhance both close-quarters and precision shooting?A: The ballistic circle reticle combines the rapid acquisition benefits of a circle dot with precise holdover points for extended range work. The illuminated circle provides fast target acquisition in close quarters, while the integrated ballistic references enable accurate shots without turret adjustments.Why Choose Professional Optics?At Professional Optics in Split, Croatia, we specialize in providing advanced tactical and hunting optics to serious shooters across Europe.
