The AR15 or “Modern Sporting Rifle” is the most popular rifle platform on the market today, the Nra estimates that 5 million Americans own one and most own more than one.
The rifle is a semi-automatic version of the M16, which has been used by the U.S. Military since the conflict in Vietnam. Though it has seen various improvements through the years it is still the same basic rifle that was issued in 1965. With so many people owning an AR15 there are thousands of accessories for the rifle platform available. The most common accessory being an optic, it is also the most common accessory I see mounted incorrectly in our shop “Volunteer Gun Shop.”
The reason being for an improper mount is that the AR15 or “Modern Sporting Rifle” has no drop in the stock from the check rest to the action top, unlike a traditional long gun. Most users mount the scope on a traditional rifle as close to the barrel as possible, which would be correct on a traditional long gun, but this creates a problem on the AR15. It will not allow you to get your head low enough to get a proper sight picture threw the scope. It also slows the speed in which the user can shoulder and fire the rifle accurately. There are several mounting options on the market especially designed for the “Modern Sporting Rifle” or MSR for short. Company’s like Nikon Burris Leupold just to name a few all have many different mounts on the market ranging in price from $40.00 -$200. The most popular mount we sell is a 1” riser. The riser mounts to the rifle, then your traditional rifle rings mount on top of the riser. This will get the scope up to the proper height for fast and accurate target acquisition. The second most popular style mount is a P223 mount by Nikon, this two-piece mount will accommodate very short scopes unlike the Nikon m-223 1 piece mount that will not accommodate shorter scopes designed especially for MSR’s. These are all good choices and there are plenty of items out there to get the job done right, if you have been having trouble acquiring the sight picture threw a scope on your AR15 now you know why.
