NOTICE

This is a 3D-printed aftermarket accessory compatible with the Horizone Redback pistol crossbow. It is not an original Horizone product or OEM replacement part.

This accessory is intended to improve handling and provide shoulder support only. It does not increase draw weight, arrow velocity or otherwise modify the performance of the crossbow.

Due to differences between printers, filaments and slicer settings, some post-processing may be required, such as sanding, deburring or reaming holes to the final size.

Check all dimensions before assembly. Do not overtighten the screws, as this may damage the printed parts.

Use at your own risk. Always follow the manufacturer's safety instructions and ensure that printing, owning and using this accessory is legal in your country or region.
