Let’s Dive into American Defense Manufacturing 1-Piece No Offset QD Mount

The American Defense Manufacturing 1-Piece No Offset QD Mount is a precision-engineered optic mounting solution designed for AR-10 platforms and bolt-action rifles utilizing chassis systems. American Defense Manufacturing (ADM) is well-regarded for its robust and reliable mounts, and this model is no exception, offering a rock-solid platform for high-powered optics. This mount features their patented QD Auto Lock Lever system, ensuring secure and repeatable attachment to Picatinny rails.

My primary motivation for seeking out the ADM mount stemmed from my frustration with inconsistent zeroing on my AR-10 after optic swaps. I needed a repeatable, reliable mount that could withstand the recoil of a .308 without shifting or losing zero. I was specifically looking for a one-piece design for added rigidity and a quick-detach mechanism for easy optic changes in the field.

Upon unboxing, the ADM mount immediately impressed me with its robust construction and clean finish. The hard coat anodized aluminum felt substantial and the QD levers operated smoothly and positively. The machining was precise, with no sharp edges or imperfections visible. It felt like a premium product worthy of the American Defense Manufacturing name.

I considered a few other mounts, including offerings from Larue Tactical and Midwest Industries. Ultimately, I chose the American Defense Manufacturing 1-Piece No Offset QD Mount because of its reputation for repeatability and the proven reliability of the QD Auto Lock Lever system. Plus, the no-offset design was perfect for my AR-10 setup with a full-length handguard.

My initial impression was overwhelmingly positive; the ADM mount exuded quality and seemed like a serious piece of kit. I was excited to get it mounted and see how it performed at the range.

Real-World Testing: Putting American Defense Manufacturing 1-Piece No Offset QD Mount to the Test

First Use Experience

I first tested the American Defense Manufacturing 1-Piece No Offset QD Mount at my local shooting range, mounting it on my AR-10 chambered in .308 Winchester. The optic I used was a Vortex Viper PST Gen II 3-15×44. The range offered a variety of distances, from 50 to 300 yards.

The ADM mount performed flawlessly in dry, sunny conditions. Mounting the optic was straightforward, and the QD levers locked securely onto the Picatinny rail with no wobble or play. After zeroing the rifle, I removed and reattached the mount several times, and the zero remained consistent within acceptable margins.

Ease of use was excellent; the QD levers are intuitive and require no tools for adjustment. After a few practice runs, I could confidently remove and reattach the mount in a matter of seconds. There were no surprises or issues after the first range session.

Extended Use & Reliability

After several months of regular use, the American Defense Manufacturing 1-Piece No Offset QD Mount has proven to be exceptionally reliable. It has held up well to the recoil of the .308 cartridge, with no loosening or shifting of the optic. The T3 Mil-Spec Anodize finish shows no signs of wear, despite being exposed to the elements.

Maintenance is simple; I wipe down the mount with a clean cloth after each range session to remove any dirt or debris. The QD levers still operate smoothly, and no lubrication has been necessary. Compared to other mounts I’ve used in the past, the ADM mount significantly outperforms them in terms of repeatability, durability, and ease of use. I am thoroughly impressed with its performance.
