Help mounting a scope to an AR15

What kind of shooting so you use your AR for? Plinking at the range? Hunting? etc. You may want to try a one piece scope mount just cause it's easy to install and only a couple things you need to factor in. The scope mount you use is going to depend on the scope you use. There are two more common tube sizes of scopes, either 1" or 30mm, which will determine the scope ring size you use. Also you plan on using a 6-24x scope? Whats the bell diameter? Prob 40 or 50mm. When looking for a mount there should be specs that state how big of a scope you can use with that particular scope mount. Look at some of the pics in the centerfire rifle photo gallery section so you can get an idea where to place the mount and see some scope configurations. The eye relief is the distance from your eye to the back of the scope or rear scope lens. Best way to make sure your eye relief is correct is when you look through the scope and it's clear, no black rings. Some guys use loctite, if you do use blue!! Hope that's a start....

Scope leveling, the correct way is to level your rifle in a gun vise, using a scope level, level the scope to your rifle. I dont have either so I use a bipod and my eye.

Inkedshooter, thanks for responding and for the advice. I plan on plinking at the range, no hunting or competition shooting. Definitely will be using a one piece Bobro or LaRue mount. The 6-24 scope tube size is 30 mm with a bell of either 44 or 50 mm. I have not decided on bell size, yet. Yes, blue Loctite only.

Here's some motivation for you.... same scope you are using, on an American Defense QD mount. This is my Mk12 Mod 1 kind-of clone using Wylde chambered receiver and 18" DPMS 1-8 barrel, for a range/varmint gun out to 600 yds or so.

If you have access to a laser boresighter, it can really simplify the zeroing process. Just remember to allow for parallax when sighting in at close ranges, say at 100 yds or less (i.e point of impact is 2" below point of aim). For a high power scope, you should try to match POI/POA at 300 yds, or at whatever range you typically will be shooting at.

A small hint - check the ring surfaces on your mount for burrs and rough spots, remove them if needed, and make sure you evenly tighten the clamp bolts (i.e. left to right and front/back, like tightening the bolts on a car wheel) to prevent marring the finish on the scope tube.

Have fun!
