Luther, guest, from RI, United States, asked on November 20, 2018

How much space between the rings? I need 3-1/2 inches minimum for an ATN X-sight Pro.

A
Answered by Rod, member, from FL, United States, on February 02, 2019

The measurement from outside of ring to outside of ring is 4 inches, from inside to inside 2 1/2 inches, you can probably get another 1/4 inch apart if you let it hang off a 1/4 inch, the rings are 3/4 inch wide, you can remove one of the rings and use it with one ring this is how I use them on my red dots

Is it tall enough to clear my M4 front sight? Thanks

The NcStar Ar15 Qr Weaver Mount is specifically designed for AR pattern rifles. Its centerline height will not be high enough to fully clear your front sight post. However, when using a magnified optic, the front sight post will only be visible as a slight blur in the bottom half of your optic, as it will be completely out of focus.
