Hattila 3-9x40 Scope — Variable Magnification for 21 mm Rail Crossbows
Designed specifically for crossbows equipped with a 21 mm rail, this Hattila 3-9x40 scope is especially well suited for crossbows with a draw weight of 175 lbs and above. Its 40 mm objective lens puts it a step ahead of standard 4x32 optics: the larger objective collects more light, significantly improving image clarity in dim conditions, such as dense woods or early dawn hunts.
The variable 3-9x magnification is adjusted via a rear ring on the scope, allowing shooters to tailor the field of view based on target distance. Two independent turrets control point-of-impact zeroing: the side turret manages windage — turning clockwise corrects a right-shifted impact, counter-clockwise corrects left — while the top elevation turret adjusts vertical trajectory using the same principle. These crossbow sighting accessories deliver precise adjustments for both target shooting and hunting.
