Indexing Your Scope Mounts – Why It’s Important

News Desk

STTU (Specialized Tactical Training Unit) recently took a look at the American Defense UIC rifle to discuss indexing your scope mount. As you can see in the image above, their article utilized an American Defense Manufacturing UIC rifle, AD cantilevered mount, and a Leupold scope.

Why is it important to index? Because altering it will move your point of impact from original zero.

Says STTU,

“When the mount was moved one slot forward on the Picatinny rail (see arrow), the grouping at 100 yards moved 10 inches to the left. When moved back to the last slot on the receiver the group returned to zero. The reason for this is that the rail on the handguard is not integral to the receiver, so not machined in one monolithic piece. So while the rails appear to be in line, there is sufficient offset to throw the shots 10 inches to the left at 100 yards.”

Read the remainder right here on the STTU website and get your learn on.
