The RPG-7 Boresighter was imagineered by the BHI design and development gnomes to allow you to calibrate your optical sights.
Made from aircraft grade aluminum and hard coat anodized for wear protection, the Boresight has been machined to exacting tolerances while taking into account the bore dimension of varied countries of manufacture.
Instructions for usage included. Like one of the gnomes told me, beats the hell out of looking through the tube with bubble gum holding strings on the bore.
The boresight is available from Blackheart International.
