Mounting Your Scope
When a scope is purchased, mounting hardware is generally not included. There are two different types of scope mounts, so it is important to know which one is needed. It is always best to use rifle scope mounts that are compatible with the rifle that is being worked on, but adapter kits are available useful.
Ring mounts are very reliable mounts. These consist of two rings that surround the scope and attach to the rifle with a 30-millimeter connection. This connecting piece is also known as a, “dovetail,” and grips similarly to dovetailing inside wooden drawers.
Not all ring mounts are the same size. One-inch is common. This is the diameter of the scope at its narrowest point. Some mounts are, “high,” or, “extra high.” This refers to how tall they are. Larger scopes required taller mounts. Scopes with objective lenses 50-millimeters or larger will require tall ring mounts.
Some ring mounts have holes in their bases. This allows for open-sight shooting while the scope is mounted. See-through mounts are great to have for times when using a scope is not appropriate.
Never over-tighten scope rings. This is known to permanently damage scopes.
Picatinny mounts are other great rifle scope mounts. These are steel rails with evenly spaced slots. A scope will only use two slots at once, though it can be remounted back and forth to adjust for eye relief.
Sometimes picatinny mounts come permanently attached to new rifles. In such cases, rings can still be used though an adapter would be necessary to provide the 30-milimeter dovetail. More commonly, adapter kits are used to mount picatinny scopes onto rifles made for ring mounts.
When it comes to mounting a scope, high-quality hardware is essential. There is a potential for lower-quality adapter kits to cause a loss of accuracy. If there is movement at any of an adapter’s contact points, the scope is no longer zeroed. Precision machining is key when it comes to scope mounts and especially when using an adapter.
Always make sure that the scope mounts are the correct type and size.
