| So, I am planning on dropping a scope on my a4 clone so I can coyote hunt with it. I noticed there is a hell of a lot more scope mounting options for the ar compared to bolt guns.... I plan to mount my old deer hunting scope, a redfield (freshly rebuilt) 4x scope. Should I just use a set of high rings and mount directly to the receiver or should I use a riser with a set of rings or should I buy a mount?. I want the front sight post to be in the lower 1/4 of the scope or lower if possible but still have a good cheek weld. |

This is what I would use:

Forget about the front sight post. You will not see it at 4x. Your scope cannot focus that close and its presence is optically invisible.
You will probably not be able to get the scope mounted on the very short AR15 receiver rail with bolt gun rings. By the time you move the eyepiece forward enough for proper eye relief, usually at least with its rear even with the rear of your charge handle or even an inch or two more forward, your turrets will force the front ring out completely off of the front of your rail. You must either use a one piece cantilever mount or put a longer riser between the rail and your rings. If you do the latter, you are stacking mounts with more screws to work loose and destroy your zero. Also, you may end up with the wrong scope height. You want to match the line of sight that occurs when you put your cheek into the AR stock. That is about 1.4"-1.5" above the top of the Picatinny rail. The center axis of your scope should be on that plane. One piece cantilever scope manufacturers have taken the guesswork out of this by making their mounts to both move the scope forward and up to match the natural eyesight plane to give you good eye relief and solid cheek weld. For a fixed mount, the Leupold Mark 2 IMS, at about $100 does all of this correctly and is rock solid. If you need return to zero QD capability, the most respected choices are LaRue, Bobro, and ADM. I have the LaRue LT-104 and like it. I also have other LaRue and ADM mounts, and they work well. No personal experience with Bobro, although it is held in high regard here as well. These mounts are all in the $180-$250 range, but well worth it. If you are on a tight budget or just want to experiment, Nikon's two piece AR specific P-mounts are only $50. They also cantilever the scope forward and up. Not as secure as a a one piece, but they seem to work. |

Forget putting the front sight in the bottom quarter, your scope will be too high. Like MS556 said, it really won't be visible anyways. I like a mount around 1.5" to centerline, I'm willing to go lower, but I try to avoid going any higher. You will want some forward offset, how much you want depends on your preferred shooting position and the eye relief of your scope. I have used Larue, Bobro and ADM and all work. I generally prefer Larue and Bobro. If you are on a tight budget I would look at the Primary Arms extended mount. http://dsgarms.com/padlxsmext http://dsgarms.com/padlxsm |

In addition to the QD and PA mounts mentioned above, another budget mount option is the Nikon M-223 mount for $63.32 shipped. I like mine very much. I don't know who makes it for Nikon, but it is labeled Made in USA.
I have my 30mm tube scopes mounted in Larue and Aero Precision mounts. Aero also makes a nice 1" mount, but it's been sold out since forever and I don't know when their mounts are coming back in stock. |
