Quick Answer
For most rifles, mounting a scope 1-2 inches above the action is ideal, allowing a clear view of the target and sufficient clearance for the bolt. On bolt-action rifles, mounting the scope 1.5 inches higher than the receiver sight is a good starting point. On semi-automatic rifles, aim for 1 inch above the action.
Optimal Mounting Heights for Bolt-Action Rifles
When mounting a scope on a bolt-action rifle, consider the rifle’s design and the shooter’s preference. Start by aligning the scope’s centerline with the rifle’s bore. Then, raise the scope 1.5 inches higher than the receiver sight to ensure a clear view of the target and allow the bolt to clear. For example, on a Remington 700, the ideal mounting height can be achieved by placing the scope 1.25 inches above the receiver ring.
Mounting Heights for Semi-Automatic Rifles
On semi-automatic rifles, the scope should be mounted 1 inch above the action to allow the ejection port to clear the scope and prevent obstruction. This is crucial for rifles like the AR-15, where the ejection port is typically higher than on bolt-action rifles. When mounting a scope on an AR-15, consider the rifle’s rail system and the scope’s mounting height to ensure a secure and functional setup.
Considerations for Specialty Rifles
For specialty rifles like muzzleloaders or break-action rifles, the optimal mounting height may vary depending on the rifle’s design and the shooter’s preference. In general, it’s essential to ensure the scope is mounted high enough to clear the action or breech, while still providing a clear view of the target. When in doubt, consult the manufacturer’s guidelines or seek advice from an experienced shooter or gunsmith.
