How to Mount Rifle Scope?

If your mounts are faulty, shaky, or inappropriate to your rifle or you as a shooter, it doesn’t matter how refined your sight is. You won’t hit the target without a proper mount. 

Some shooters hire professional gunsmiths to mount their rifle’s scope, but you can mount your rifle scope yourself without fearing destroying your rifle’s precision. Scope mounted yourself highly matches your measurement. 

Mounting a rifle scope can be time-consuming and challenging. Read this easy step-by-step guide to mount your scope correctly. 

Step 1: Select High-Quality Rings and Mounting

Purchase high-quality bases and rings. Choose steel-made and Lightweight Alloy one-piece base/ring equipment because they are more durable. They’re light and sturdy. For the base, buy steel Picatinny-spec rail-type for all-around adaptability.

The mounting hardware you buy must match the scope’s design if your rifle scope requires mounting rings. The scope’s body mounts inside the ring. Be sure they have the correct inside diameter. 

  • If you’re not sure what kind of hardware you’ll need to install your scope, ask the merchant where you bought it for help.
  • If your rifle came with a factory-installed scope, you wouldn’t need to buy any additional hardware.

Step 2. Install the Mount Base Correctly

Not every firearm is pre-installed with mounting on it. As a result, certain rifles require a specific adapter referred to as a base to link the scope rings to the firearm.

The scope base remarkably influences your optics configuration. If you want accurate shots, don’t scrimp on the quality of the mount base, just like you shouldn’t on the scope.

The optic mount base is of two types:

  • First, the one-piece base is more rigid and straightforward for added MOA (Minute of angle) elevation.
  • Second, a Two-piece base is handier in loading and unloading the rifle with a clear sight of the target. 

Clean the mounting surface and gently screw up your preferred base. Since the recoil of your rifle can cause your screw to wiggle, use a removable thread locker and allow it to fit for 24 hours for best results. 

Step 3: Install the Scope Rings Correctly

Scope rings are essential in keeping the mount aligned. The rings encircle the scope and secure it. Screw the bottoms of the rings at the bases. Scope rings depend on the size of the scope, and it matches the scope’s body tube diameter. Most rings use 35-45 inch-pounds.

Loosen the securing screws, position the lower half of the ring to your desired position on the base, gently screw your scope rings as low as possible while still allowing for clearance. Ensure that the scope base and ring fit perfectly and place some oil in between for rust prevention. 

Step 4: Install the Ring Tops and Scope

Place your scope in the newly fitted rings, gently install the ring tops so that it doesn’t damage your scope body. Don’t torque the screw down so that you can easily set eye relief.

Make sure your scope’s magnification is to the highest setting. It would be best to have a full-sight picture with your rifle shouldered and your head in a natural position. Move the rifle’s scope forward and backward until you achieve the correct position. 

Step 5. Level up Your Scope

Place your level on the central turret. Adjust your rifle scope so that the reticle is perpendicular to the bore. Leveling helps in zeroing the scope. Maintaining a level reticle will assist you in accurately compensating for windage and height in the field.

Use a sight leveling kit to even gaps between the top and bottom of the rings on each side. Gradually tighten the top ring screws to manufacturer torque specs, alternating back and forth and keeping the crosshairs level.

Step 6: Set Proper Eye Relief Distance

Setting the eye relief will help prevent the black halo that can appear when looking through a rifle optic and eye discomfort caused by the rifle’s recoil.

For this, drift the scope forward or backward to your eye until the entire field is visible. Make sure your vision stays the same and doesn’t get any less blurry. Adjust eye relief by looking through the scope from different angles until you can get a clear picture. 


Assuming you’ve used quality components and, therefore, the correct mounting technique, your rifle scope is now as fail-proof as you’ll humanly make it. It would be best to remember that mounting scope is a repetitive process and scope mounting is a necessary skill that every shooter should know.
