Mounting a scope on your AR-15 for the first time is a difficult task. It takes a lot of time and patience, and sometimes a few tries, to nail it perfectly. But don’t worry, we got your back covered.

Here’s How You Can Mount a Scope on AR 15

This guide will help you mount your rifle scope in the first attempt.

Items you need:

• Torque wrench – used to attach the rifle scope mount to your AR-15
• Scope mount – the link between the gun and scope; the part which attaches the scope to the gun
• Hex bit screwdriver– used for tightening the screws on the scope
• Bubble level – used to level all the parts for complete accuracy during installation
• Rifle scope – the scope you have chosen to your AR-15
• Gun or shooting rest – used to hold your AR-15 rifle in place for the installation.

Step 1 – Preparation:

You need to prepare your rifle and tools for the installation. Make sure that your rifle is empty, unloaded and the safety is on. Gun safety is vital not only during storage but also in processes such as accessory attachment/detachment, cleaning, etc. Fix it in the shooting rest so that it’s stable and tight for being worked on. Use the bubble level to check level. Checking the level on every step is key to successfully mounting your scope in the first attempt, as a mistake on any level could lead to wrong installation of the scope, ruining all your hard work.

Step 2 – Attaching the mount:

Attach your scope mount to the rifle. Place the mount on the top of the AR-15 and tighten its screws by hand so that it holds it place properly. Take the torque wrench and tighten the screws to secure it in place. Be careful about the torque limit on the screws as given by the scope mount instructions. Tightening it more could result in the mount being spoiled. Use the bubble level again to check for the level of the mount. Check both parallel and perpendicular levels to make sure it’s leveled. Adjust by tightening or loosening the screws to achieve proper level so that you’re able to go ahead.

Step 3 – Attaching the scope:

Your scope mount is now secure and ready for the rifle scope to be attached. Place the scope carefully on the mount rings, on equal and flat surfaces on both sides. Place the top of the scope rings and tighten the screws with the hex bit screwdriver to about 80%, in an X pattern. This helps keep the scope even. This is the final time where you can adjust eye relief of the scope.

Step 4 – Finalizing and leveling:

Level your scope by placing the bubble level on some flat knob or adjustment of the scope to check parallel and perpendicular levels. Once satisfied, tighten the screws of the mount rings in the same X pattern for proper tightening. Re-check the AR-15 for the last time for levels. Check the alignment of the reticle. This can be done by aligning the reticle to an object that it already been verified vertically by the bubble level.

Your AR-15 is ready to use with the rifle scope. Safe and happy shooting!
