The Shotgun Collimator allows for precise alignment between the eye and front sight of any shotgun, both horizontally and vertically with regards to the rib.
The optimal placement for the collimator is 10 cm from the start of the barrel (closest to face as seen in product image). When the front sight is clearly visible within the device, then the shotgun is correctly positioned on the shoulder. This tool is especially helpful for adjusting ergonomic stocks and is constructed with anodized aluminum and a magnet to easily secure it to the rib during adjustments.
Available sizes: 8MM, 10MM, 11MM, 12MM (rib width).
