This guide details the process of adjusting the mount on a Mosin-Nagant PU Sniper rifle, as explained by Mike B of TFB TV. It covers coarse elevation adjustments using the mount's screws and fine windage adjustments by filing or shimming the mount's tongues. The video emphasizes the unique moving-reticle system of the PU scope and how to zero it effectively.

Quick Summary

The Mosin-Nagant PU sniper mount's adjustment system is unique: elevation is adjusted via screws at the rear of the mount, pivoting on a ball joint, while windage is corrected by filing or shimming the mount's rear tongues. The PU scope itself has a moving reticle, unlike modern optics.

Frequently Asked Questions

How is windage adjusted on a Mosin-Nagant PU sniper mount?

Windage on the PU sniper mount is adjusted by altering the rear 'tongues' of the mount. This is typically done by filing them down to move the point of impact right, or by adding shims to move it left, as there are no dedicated windage screws on the mount itself.

What is unique about the PU scope's adjustment system?

The PU scope features a moving-reticle system. Unlike modern scopes where the internal optics adjust, the entire reticle within the PU scope moves when the elevation and windage drums are turned. This requires a different approach to zeroing and adjustment.

How do you make coarse elevation adjustments on the PU sniper mount?

Coarse elevation adjustments are made on the mount itself. After loosening the main clamping screw, you adjust vertical screws at the rear of the mount. This causes the mount to pivot on its front ball-and-socket joint, effectively raising or lowering the point of impact.

Can the PU scope mount be quickly detached?

No, the PU scope mount is detachable but not considered 'quick-detachable.' It uses a large clamping screw and other fasteners that require tools and time to remove and reattach, unlike modern QD mounts.
