What You'll Need

Before we get our hands dirty, let's go over the tools and materials you'll need for this installation. First off, you'll obviously need your 308 Tactical Rifle Scope. You can check out our 30mm Tactical Rifle Scopes, Mil Dot Tactical Rifle Scopes, and Compact Tactical Rifle Scopes for some great options.

In addition to the scope, you'll need a good set of scope rings. These come in different sizes, so make sure to pick the ones that fit your scope tube diameter. You'll also need a torque wrench. This is super important because over - tightening or under - tightening the screws can mess up your scope's alignment and performance. A small flat - head and Phillips - head screwdriver will also come in handy for adjusting and tightening some parts.

Step 1: Prepare Your Rifle

The first thing you gotta do is make sure your rifle is unloaded. Safety first, always! Remove the magazine and check the chamber to ensure there are no rounds. Once you've confirmed that, clean the rifle's receiver where the scope rings will be mounted. Use a clean cloth and some gun cleaner to get rid of any dirt, oil, or debris. A clean surface will ensure a better and more secure fit for your scope rings.

Step 2: Mount the Scope Rings

Now it's time to mount the scope rings on the rifle. Start by placing the bottom halves of the scope rings on the rifle's receiver. Align them with the mounting holes on the receiver. Make sure they're straight and centered. You can use a scope leveling tool to help with this. Once they're in the right position, insert the screws through the holes in the scope rings and into the receiver. Don't fully tighten the screws yet; just give them a few turns to hold the rings in place.

Step 3: Install the Scope in the Rings

Carefully lift your 308 Tactical Rifle Scope and place it into the bottom halves of the scope rings. Make sure the scope is centered within the rings. You want the scope to be parallel to the rifle barrel. Look through the scope and check the alignment. If it seems off, adjust the position of the scope slightly.

Once you're satisfied with the position, place the top halves of the scope rings over the scope. Align the holes in the top and bottom halves of the rings and insert the screws. Now it's time to use your torque wrench. Follow the manufacturer's recommended torque settings for the screws. Usually, it's around 15 - 20 inch - pounds. Tighten the screws gradually and evenly, alternating between each screw to ensure a balanced and secure fit.

Step 4: Check the Eye Relief

Eye relief is the distance between your eye and the scope's eyepiece. It's important to get this right because it affects your comfort and accuracy. Look through the scope and adjust your position until you have a clear and full view of the reticle. You should be able to see the entire field of view without any black edges. If the eye relief is too short, you might get a "scope bite" when the rifle recoils. If it's too long, you won't be able to see the full field of view.

Step 5: Zero Your Scope

Zeroing your scope means adjusting it so that the point of aim (where you're looking through the scope) matches the point of impact (where the bullet hits the target). This is a crucial step and usually requires some time at the shooting range.

Set up a target at a known distance, usually around 25 yards for an initial zero. Take a few shots at the target. If the bullets are hitting off - center, use the windage and elevation adjustment turrets on the scope to make corrections. The windage turret adjusts the left - right movement, and the elevation turret adjusts the up - down movement. Make small adjustments and take more shots until the point of aim and point of impact match.

Step 6: Final Checks

After zeroing your scope, give everything one last check. Make sure all the screws are still tight. Check the alignment of the scope again. Look through the scope from different positions to ensure the eye relief remains consistent.

If you're happy with everything, you're good to go! Your 308 Tactical Rifle Scope is now installed and ready for action.

Troubleshooting

Sometimes, things don't go as smoothly as planned. If you're having trouble getting the scope to align properly, double - check the mounting of the scope rings. Make sure they're straight and tightened evenly. If the scope seems to be moving or shifting after shooting, it could be a sign that the screws weren't tightened enough or the scope rings aren't a good fit.

If you're having issues with the reticle not being clear or visible, it could be due to dirt or debris on the lenses. Clean the lenses gently with a lens cleaning solution and a microfiber cloth.
