The Truglo OPTI-SPEED Crossbow Scope with Weaver Style 30mm Rings delivers a bright, precise optic designed to maximize speed and accuracy for modern crossbows, featuring a 1-4x magnification with a 24mm objective and a glass-etched reticle that can be used with or without illumination depending on light and target color. This scope employs an enhanced crossbow BDC reticle that compensates bolt drop and provides accurate hold-over points from 20 to 70 yards, while a simple dial scales the reticle to match bolt velocity in the 215-450 feet per second range, ensuring reliable aiming points across a broad speed spectrum. Built for field reliability, it is waterproof, fog-proof, and nitrogen gas-filled, with fully-coated lenses to maximize brightness, clarity, and contrast, and an adjustable rheostat brightness control for variable light conditions. Durable windage and elevation adjustments use 1/2-MOA increments, complemented by a wide field of view for rapid target acquisition. The package includes Weaver-style 30mm rings and a battery, delivering a ready-to-use, high-contrast sighting solution for hunters seeking pinpoint accuracy and rapid target acquisition from a dependable OPTI-SPEED optic by Truglo.
