Front sight adjustment tool.
Designed to adjust the front sight on the Mosin-Nagant rifles and carbines. Manufactured at the 'Caliber' plant in Moscow in 1946. The plant specialized on production of the special accurate tools to repair the small arms.

Made of the blued steel. Used to accurately adjust the sniper rifles. It is not a hand-made piece of iron with two screws or a cheap Chinese replica made of aluminum but an original professional tool that was used at the military workshops to sight Mosin-Nagant rifles.

This clever U-shaped device fits under the barrel of  the rifle and cradles the sights. Has a fine thread screw for a precision zero that is long enough to push the sight all the way off of the dovetail. Just flip the tool around to go the other direction. The screw has an index line. The end of the T-handle fits into the elevation post and provides plenty of leverage to easily move even a stubborn post. Speeds up the whole process of sighting in your rifle.

An essential tool to make fine adjustments to the front sight of your Mosin-Nagant rifle. The tool is from a warehouse. Brand new condition. It has never been used before.
