This is exactly how to upgrade ELCAN Specter's QD lever mount to have tighter clamping force to retain zero better.
We have seen these bulky ELCAN prism optics being used on the battlefield deployed with special forces. The glass quality and durability for this optic is amazing, however, there is a problem with its loose QD lever mount.


The original QD lever mount works seamlessly with a mil-spec rail system. However, if the rail is not mil-spec or has any damage, the scope may lose its zero.
When a scope is not securely mounted to a rifle, it can lose zero or even detach entirely due to recoil.
The ARMS MKII QD lever is an essential upgrade for the ELCAN, offering outstanding value at just $15. This upgraded lever features an adjustable tension mechanism that provides increased vertical clamping force, ensuring a more secure mount.
If you’re dealing with an out-of-spec rail system that’s ready for the ELCAN, the ARMS MKII QD lever allows you to confidently and securely mount it on your rifle.
