Yes, How To Mount A Scope On A Ar15

We follow these exact steps while mounting our AR 15 rifles. Hence, we are writing this from personal experience. We hope, you find this helpful.

  • We start by clearing the rifle, like removing magazines and bullets (also look for if there is one in the chamber)
  • Use the rubbing alcohol and rags or patches (whichever you use) to clean the rail, screws, and mount
  • This will assist you to remove the excess oil and get a grip while installing the scope
  • Then we use the degreaser to clean the mount along with its hardware
  • We assume that you are using a gun vice, so you must place the scope on the upper part of the receiver
  • As for non-cantilever mounts, you will have to place them forward
  • Start tightening the scope with the help of the torque wrench, but remember that different scopes have different torque levels, so do not overdo it
  • Double-check that if the rings are sitting flat
  • Now, place the optic into the mount and add the rings to it
  • Then test the eye relief and find a comfortable position
  • At this juncture, we usually drop the bubble level only after ensuring the rifle is leveled
  • Bring the reticle into line, arrange the crosshair in a line, and make use of the bubble level while achieving success with these things
  • Examine the balance of your weapon
  • If you are done with all these things, all you have to do is to tighten the screws one final time

You are done and have nothing to worry about it by this time. Your firearm is ready, clean, and secured. What more can you ask for? Yes, it is that easy! You are good and have nothing to fear about.

Lapping

We have not included lapping in this discussion because unless you are going for a long-range shooting, may be over 600 yards, the process we have mentioned is good to go. There is no need to sand the rings (as that is what lapping is) for short-range shooting, as that is the truth.

Yes, but if you still want it, then you must take your weapon to a gunsmith. Their services are way more reasonable than getting a lapping kit for the rings. Look you are free to take a call for this, but we say there is no need as you already have done enough by mounting the scope on your own.

Your scope sits perfectly well on your AR 15 and you have nothing to worry about. Trust us as that is all you need to know about mounting a scope on an ar. Don’t worry, you will be fine.
