Lever Locks Suck!

John "Shrek" McPhee, a firearms instructor, strongly advises against using lever locks for rifle optics due to their tendency to come loose. He notes that even tightening to manufacturer specifications often results in the mount loosening during use, leading to a loss of zero. McPhee advocates for traditional screw-down mounts, comparing their security to a "1/8 nut at 65 inch-pound."

Frequently Asked Questions

Why are lever lock rifle optic mounts problematic?

Lever lock mounts tend to come loose due to metal-on-metal friction, even when tightened to manufacturer specs. This loosening leads to a loss of zero, requiring frequent re-zeroing and potentially disrupting shooting accuracy and performance.

What is the main disadvantage of using lever lock optic mounts on rifles?

The primary disadvantage is their unreliability in maintaining a consistent zero. They are prone to loosening during shooting, which necessitates re-zeroing and can negatively impact marksmanship, especially in training environments where time is limited.

What alternative does the instructor recommend over lever lock mounts?

The instructor strongly recommends traditional screw-down optic mounts. He compares their secure fastening to a properly torqued nut, suggesting they offer superior stability and zero retention compared to the convenience of lever locks.

How does a loose optic mount affect shooting?

A loose optic mount causes a loss of zero, meaning your point of impact will shift from your point of aim. This requires constant adjustment and re-zeroing, which is time-consuming and detrimental to consistent shooting performance and accuracy.
