Duration: 33:48

This guide details the installation of the MDT One-Piece Competition Scope Mount, emphasizing proper torque specifications and a unique tightening sequence to ensure optic security and alignment. It highlights the importance of Vibra-Tite for thread locking and the necessity of a tall target test to verify scope tracking and plumbness. The video also touches on optimal scope height for chassis rifles and the benefits of robust, heavy-duty mounts for high-recoil applications.

Quick Summary

The MDT One-Piece Competition Scope Mount features a 1.34-inch height, ideal for chassis rifles, and uses T25 Torx screws. It requires a specific tightening sequence for the top ring caps to 15 inch-pounds to prevent ring pull, and Vibra-Tite is recommended over Loctite for thread locking. Always perform a tall target test to ensure proper scope alignment and tracking.

Frequently Asked Questions

What are the recommended torque specifications for the MDT One-Piece Competition Scope Mount?

The MDT One-Piece Competition Scope Mount specifies 65 inch-pounds for the cross bolts that attach the mount to the rifle's Picatinny rail. For the top scope ring cap screws, the recommended torque is 15 inch-pounds, following a specific tightening sequence outlined in the instructions.

What is the recommended height for the MDT One-Piece Competition Scope Mount, and why?

The MDT One-Piece Competition Scope Mount featured has a height of 1.34 inches. This height is considered ideal by the instructor for most scopes, particularly on chassis rifles, as it allows for a comfortable shooting position without excessive neck strain and offers no ballistic disadvantage.

What is the unique tightening sequence for the MDT scope mount's top ring caps?

MDT's instructions for the top scope ring caps involve tightening screws 1, 2, and 3 on one side to 15 inch-pounds first, before moving to the other side (screws 4, 5, and 6). This sequence aims to prevent ring pull and ensure even clamping pressure on the scope.

Why does the instructor recommend Vibra-Tite over Loctite for scope mount fasteners?

Vibra-Tite is recommended because it acts as a thread locker that remains gummy and works against tightening, preventing over-torquing and ensuring consistent clamping force. Loctite, conversely, has lubricating properties that can lead to over-tightening and potential damage to the scope or mount.

What is the 'tall target test' and why is it crucial for scope mounting?

The tall target test is a verification method where a shooter fires at a tall target at close range and observes if the point of impact aligns with the reticle's center when the scope is adjusted. It's crucial for confirming the scope is plumb, tracking accurately, and free from internal issues, regardless of the mounting method used.
