TM4.5-18x40 Rifle Scope

The TM4-5-18X40 Rifle Scope delivers versatile precision for mid-to-long-range engagements, featuring a 4-18X variable magnification range and 40mm objective lens for balanced light gathering. The MIL-STD reticle (MIL-DOT style) enables holdover calculations for bullet drop compensation, while multi-layer broadband coating enhances light transmission by 92% for clear, high-contrast imagery in dawn/dusk conditions. Constructed from rugged 6061-T6 aircraft aluminum, this scope is nitrogen-purged for fogproof performance and O-ring sealed for IPX6 waterproofing, with a shockproof design that withstands heavy recoil from .300 Win Mag to 6.5 Creedmoor. Engineered for tactical accuracy, the side focus (SF) parallax adjustment eliminates image distortion from 50–500m, while 1/4 MOA finger-adjustable turrets offer precise windage/elevation corrections with audible clicks. The fast-focus eyepiece ensures rapid reticle clarity, and the zero-stop mechanism maintains zero through repeated adjustments. Weighing 22oz with a 14" length, this scope mounts seamlessly on Picatinny/Weaver rails, ideal for AR platforms, bolt-action rifles, or precision hunting setups. Whether engaging targets at 100m or dialing in for 500m shots, the TM4-5-18X40’s combination of tactical functionality and optical performance makes it essential. The hard-anodized finish resists abrasion, and the extended eye relief (3.5–4") reduces eye strain during prolonged use. Backed by a design that prioritizes reliability in the field, this scope is built for hunters and tactical operators who demand consistent accuracy across diverse environments.
