My journey to finding the perfect mount for my Holosun 509T began when I decided to build a dedicated AR pistol.

Before settling on the ADM mount, I considered options from LaRue Tactical and Scalarworks. Ultimately, I chose ADM due to their reputation for reliable QD systems and the availability of a specific mount designed for the 509T footprint.

Real-World Testing: Putting American Defense Manufacturing Holosun 509T QD Mount to the Test

First Use Experience

I first tested the American Defense Manufacturing Holosun 509T QD Mount at my local shooting range, mounting it on my newly built AR pistol chambered in 5.56 NATO. The range provided a controlled environment to zero the optic and assess the mount’s stability and ease of use. I was shooting at distances ranging from 25 to 100 yards.

The performance of the mount was consistent across varying conditions, even during a slightly drizzly afternoon. Despite the dampness, the ADM Auto Lock lever remained easy to manipulate and provided a secure lockup. Adjusting the lever tension was simple, requiring only finger pressure, and it was intuitive to use.

The mount was incredibly easy to use. The Holosun 509T attached to the mount without any issues, and the QD lever allowed for swift installation and removal from the Picatinny rail. The co-witness height was also comfortable, allowing for quick target acquisition.

Following my first session, I noted that the mount held zero perfectly, with no noticeable shifting after multiple removals and reattachments. There were no unexpected issues, and the mount performed as expected, contributing to a positive first experience. The American Defense Manufacturing Holosun 509T QD Mount instilled confidence right away.

Extended Use & Reliability

After several months of regular use, the American Defense Manufacturing Holosun 509T QD Mount has proven to be exceptionally reliable. It has been subjected to numerous range sessions, tactical training drills, and even a few weekend camping trips, all without any issues. The mount has consistently maintained its zero and has not exhibited any loosening or shifting.

The ADM mount displays excellent durability with only minor signs of wear and tear, primarily some slight scuffing on the finish from rubbing against other gear in my range bag. The Type 3 Mil-Spec anodizing has held up incredibly well, resisting scratches and corrosion even after exposure to moisture and temperature changes. Maintenance has been minimal; a quick wipe down with a lightly oiled cloth after each range session is sufficient to keep it in top condition.

Compared to other QD mounts I’ve used in the past, the American Defense Manufacturing Holosun 509T QD Mount outperforms them in terms of ease of use, stability, and overall build quality. The ADM Auto Lock lever system is more secure and user-friendly than competing designs, offering peace of mind that the optic will remain firmly in place. The reliable performance exceeded my expectations.
