This 30mm scope mount from American Defense Manufacturing is made with the intent of letting you put high power glass on your flat top AR-15 upper receiver.
One of the main features of this scope base is that it gives you an added 20 MOA of scope elevation. This 20-MOA is built into the base. This added elevation range is extremely useful for long range shooting, as it will let you dial in your scope for extremely long shots.
This scope mount has an integrated cantilever style. This allows you to have the mounting surface to the rear and throw the scope out forward. This is a preferred way to mount a scope on an AR-15 rifle, as standard, non-cantilever scope mounts generally leave the scope in a position where eye relief is an issue. Also, by having the mounting surface completely on the upper receiver, this ensures a firm mounting location.
The scope mount was made to be durable. This product was machined from durable 6061-T6 aluminum. This aluminum is finished in a T3 mil-spec hard coat anodizing. This gives the scope base a black finish and enhances corrosion and wear resistance.
The American Defense Scope mount comes with an innovate quick detach system. This system was engineered by ADM and ensures a firm lock-up to your Picatinny rail. The QD is adjustable to conform to mil-spec Picatinny rails, as well as other rails that may be slightly out of spec. The lever can be configured to lock either to the forward position, or to the rear.
