Leupold 177093 Mark AR Integral Mounting System 1-Pc Base & 1" Ring Combo For AR- Style Rifle Black Matte Finish

Excellent product !! NO issues at all !!

These mounts are fantastic on AR style rifles, have several in use 0 complaints.

If you're looking for a scope base for your AR, then you have to find a set of rings that fit the scope tube. Don't forget that you'll have to insure that the ring set are perfectly aligned with the base. STOP LOOKING. This integrated mounting system solves all your problems and it's solid as a rock. Comes in either 1" or 30mm so either way, you've got a great mount. I've not only used this mount on two of my rifles but suggested it for two of my friends. They appreciate the "one stop shop" but especially the convenience. Need to work on the rifle and don't want to take the chance of hurting the scope, no problem. Mark the mount positions on the rail, loosen the mount bolts, remove the scope which is still securely in the rings. Perform your work, remount the mount in the original rail locations, tighten the bolts, and you're back in business. Note: you might be off target by an MOA or so after the remount so double check your rifle before doing any serious work. This is a solid mount and of course, it's a Leupold.

Light and mounts firm with no movement from the scope. Another quality product from Leupold

Bought it to mount on my Ruger AR15 model 556 MPR. Product quality, fit and finish excellent as one would expect from Leupold, and it allows for plenty of room for eye relief adjustment. However, product comes with no mounting instructions and the Leupold web site doesn’t have them either, so unless one knows that the Leupold lettering on the mounting system must be on the right side of the rifle one runs the risk of securing it to the rifle the wrong way. In addition, there are no instructions as to the inch-pound torque to apply when securing the mounting system to the Picatinny rail of the rifle, and I couldn’t find this information in Leupold’s web site either, thus the 4-star rating.
I torqued the Torx head screws to 40 inch-pounds based on prior experience with aluminum mounts and will re-check after I fire 150 rounds /-
