Key Features:

Built in 20 MOA Slope:  

The built in slope of the AADMOUNT allows long range shooting with scopes that have too small a range of adjustment using a flat mount or rings on AR-type rifles, DTA or Barrett long range rifles or similar rifles with integral Picatinny upper receivers.  This eliminates the need for scabbed-on "riser rails" many have been forced to used in the past.

Height:
The AADMOUNT places the centerline of the scope 1.45" above the top of the rail.  This allows room for larger scopes with 50mm and 56mm objectives even with straight rail forends and gives ample clearance for folding rear BUIS even for scopes with large ocular assemblies.  This height provides a comfortable cheek weld for AR style rifles utilizing long range/precision style stocks.

Eye Relief:
The cantilevered style of the AADMOUNT allows the scope to be mounted farther forward on AR style rifles than straight mounts or a pair of high rings so a mounting position providing more comfortable eye relief is possible.

Short Base:
The relatively short length of the base of the AADMOUNT allows maximum flexibility in mounting location on the upper receiver so you can find the location best suited to the size of the scope, length of pull, rifle's intended use and your own personal shooting style and allow plenty of room on the rail for rear BUIS.

Return to Zero:  
The AADMOUNT will return to zero within 1/2 MOA, guaranteed.

The AADMOUNT is not just "approved for use" on 50 Cal rifles, but is highly recommended for such use.  Of course, you do not need a 50 Cal to enjoy the strength, accuracy and durability the AADMOUNT provides (and the peace of mind that comes with it) especially if you subject your equipment to harsh, severe use.

Overall Strength:   
There are plenty of quick release-type mounts and cheap Chinese mounts made from cheap aluminum extrusion on the market, but when used with big scopes on big rifles for long range precision, especially when large amounts of recoil or rough treatment are present, many leave much to be desired in their performance.  It's in this type of application the AADMOUNT really shines.

The AADMOUNT was designed to be as close to indestructible as possible.  From the 10 #8-32 Grade 8 ring screws providing clamping force over a large area eliminating any possibility of scope movement without "pinching" or "ring-marking" or otherwise damaging the scope, to the three machined-in integral locking lugs providing several times more strength than is necessary, to the four #8-32 Grade 8 clamp screws providing 70% more clamping force on the rail than competing designs, to the thick cross sections of billet aluminum throughout which provide not only amazing strength but also accuracy-promoting stiffness, the AADMOUNT is simply stronger, stiffer, and more durable than any other mount on the market. 

Finite Element Analysis tools were heavily employed to optimize strength and stiffness while keeping weight at a minimum.

Ease of Removal:
While the AADMOUNT technically isn't a "quick release" mount because it requires the use of a tool, it is very fast and easy to remove taking only seconds longer than QR mounts should the scope need to be removed in the field.  One of the many advantages of using four #8 screws instead of two ¼" crossbolts/studs/nuts to secure the clamp to the rail is the only tool required for removal is the very small "L-shaped" TORX wrench (included free with the purchase of an AADMOUNT).  This wrench is very small and weighs next to nothing.  It can easily be stowed within small storage compartments of various stocks and grips so that it is always available on the rifle.  Since all required clamping force is obtained with only 35 lb-in of torque, the screws are easily loosened by hand using the small wrench.  This cannot be done with couple of large nuts torqued to 65 lb-in without a larger tool. 

Of course if your profession makes likely scenarios in which the few seconds it takes to retrieve the tool in order to remove the scope may take to long under fire, then you should get a true QD mount.  We recommend both Larue and ADM quick release mounts for this application.
