Monstrum G3
Experience exceptional range and accuracy with the adjustable 3-18x magnification of this high-performance tactical rifle scope, built for mid to long-distance shooting up to 1000 yards. Featuring a first focal plane MOA reticle, the etched crosshair remains proportional at all magnifications, providing clear, reliable ranging information and simplified holdover adjustments. Constructed from durable 6061 aircraft-grade aluminum, the scope is nitrogen-charged and weather-sealed to resist fog and harsh conditions. It includes 1/4 MOA windage and elevation adjustments with zero setting, a parallax adjustment dial for sharper focus and range estimation, and red reticle illumination with multiple brightness levels for low-light visibility. The package includes high-profile Picatinny rings, a detachable sunshade, and spring-loaded flip-up lens covers.
Sightmark Presidio
The Sightmark Presidio delivers excellent optical performance, thanks to its fully multi-coated lenses that maximize light transmission and ensure superior brightness and color accuracy. Whether you’re competing, plinking at the range, or out hunting, the clarity and image quality are exceptional. The low-profile locking turrets are a standout feature, offering quick, secure adjustments even in dynamic conditions. This scope’s rugged construction is reinforced by a single-piece 30mm tube made from aircraft-grade aluminum, ensuring it can withstand recoil and external stresses without compromising alignment. I appreciate the Presidio’s IP67 rating, which makes it dustproof, waterproof, and shockproof, allowing it to endure immersion up to 3 feet and drops of up to 3 feet. Its scratch-resistant lens coating keeps the optics in pristine condition, while the zero-stop elevation dial makes adjustments effortless and precise in any environment.
