American Defense Mfg Delta Scope Mount Black Anodized 1-Piece Cantilever w/30mm Tube Diameter for AR-15, AR-10, Review

First Thoughts on the American Defense Mfg Delta Scope Mount Black Anodized 1-Piece Cantilever w/30mm Tube Diameter for AR-15, AR-10,

In the ever-expanding world of AR accessories, finding the right scope mount can be a daunting task. The American Defense Mfg Delta Scope Mount Black Anodized 1-Piece Cantilever w/30mm Tube Diameter for AR-15, AR-10, aims to simplify that decision with its promise of rock-solid stability and quick detach capability. American Defense Mfg (ADM) has a reputation for quality, and this mount seems poised to deliver on that promise.

I’ve struggled with maintaining zero on optics across different AR platforms, always searching for a repeatable and reliable mounting solution. Many mounts claim to offer this, but few truly deliver after repeated removals and re-installations. I was particularly drawn to this mount because of ADM’s patented QD Auto Lock Lever system, which seemed like a potential game-changer.

Upon unboxing, the first thing that struck me was the heft and solid feel of the mount. The black anodized finish is immaculate, and the machining is visibly precise. It exudes quality, and its one-piece cantilever design feels inherently more robust than some of the two-piece options I’ve used in the past.

Compared to a LaRue Tactical QD mount and a less expensive Aero Precision Ultralight mount, the ADM Delta mount feels like a good middle-ground in terms of weight while being significantly more robust than the Aero Precision. It feels like it strikes a better balance between weight and durability. The LaRue is excellent, but its lever system can be a bit fiddly, which I hoped the ADM mount would improve upon.

My initial excitement was high. The American Defense Mfg Delta Scope Mount Black Anodized 1-Piece Cantilever w/30mm Tube Diameter for AR-15, AR-10, appeared to be a serious piece of kit. It looked like a mount ready to withstand serious use and abuse, which is exactly what I need for my AR platforms.

Real-World Testing: Putting American Defense Mfg Delta Scope Mount Black Anodized 1-Piece Cantilever w/30mm Tube Diameter for AR-15, AR-10, to the Test

First Use Experience

I first tested the ADM Delta mount at my local shooting range on my AR-15 chambered in 5.56 NATO. The weather was typical for that time of year – slightly humid with a light breeze. I mounted a Vortex Viper PST Gen II 1-6×24 scope to the ADM mount, making sure everything was torqued to spec.

The initial zeroing process was straightforward, and the mount held zero perfectly throughout the initial 100-round session. The QD levers felt secure and easy to operate, offering a satisfying click when locking into place. Even after removing and reattaching the optic multiple times, the zero remained consistent at 100 yards, which was a great initial result.

There were no immediate issues or surprises beyond the positive confirmation that the QD system lived up to its promise. The 1.5″ height allowed for a comfortable cheek weld, and the 2″ cantilever provided ample eye relief. I was able to obtain a clear sight picture, and the rifle was now comfortable to use.

Extended Use & Reliability

After several months of use and approximately 500 rounds fired across my AR-15 and AR-10 platforms, the ADM Delta mount has continued to perform admirably. The mount has seen range use, as well as being installed on my AR-10 during a hog hunt. It has been through various conditions: dry, dusty days at the range, and a light rain during the hog hunt.

Durability has been excellent. There are no signs of significant wear and tear beyond minor cosmetic scratches on the anodized finish, which is expected from regular use. Even after bumping it against barricades and rough handling in the field, the mount remained rock solid.

Maintenance is minimal. I simply wipe it down with a lightly oiled cloth after each range session or hunt. So far, there has been no need for any special cleaning or maintenance procedures. The American Defense Mfg Delta Scope Mount Black Anodized 1-Piece Cantilever w/30mm Tube Diameter for AR-15, AR-10, has significantly outperformed my expectations, especially compared to some of the cheaper mounts I’ve used in the past.
