Obsidian Arms QD Sling Mount M-LOK Review

First Impressions of Obsidian Arms QD Sling Mount M-LOK

The Obsidian Arms QD Sling Mount M-LOK is a seemingly simple piece of hardware, but one that can drastically improve the usability and handling of a rifle. As someone who’s spent over a decade configuring and optimizing tactical and sporting firearms, I understand the importance of a secure and reliable sling attachment point. This mount, manufactured by Obsidian Arms, promises a low-profile design, robust construction, and anti-rotation features.

My need for this particular sling mount arose from a recent build utilizing an M-LOK handguard. The limited integrated QD points on the handguard dictated the need for additional, more strategically placed sling mounting options. I picked the Obsidian Arms QD Sling Mount M-LOK due to its reputation for quality, reasonable price point ($19.99), and the fact that it is made in the USA.

Unboxing the Obsidian Arms QD Sling Mount M-LOK, my initial impression was positive. The black anodized aluminum felt solid and well-machined, and the low-profile design was immediately appealing. Compared to some bulkier QD mounts I’ve used in the past, this one seemed less likely to snag on gear or the environment.

I considered options from Magpul and BCM, but ultimately chose the Obsidian Arms QD Sling Mount M-LOK for its combination of price, features, and origin. Magpul’s offering is slightly cheaper, but lacked the specific anti-rotation design I was looking for. BCM’s QD mount is known for being robust, but the price was significantly higher for seemingly comparable functionality.

I was cautiously optimistic upon receiving the Obsidian Arms QD Sling Mount M-LOK. The quality appeared excellent, but the true test would be its performance in the field and its long-term durability.

Real-World Testing: Putting Obsidian Arms QD Sling Mount M-LOK to the Test

First Use Experience

I first tested the Obsidian Arms QD Sling Mount M-LOK at my local shooting range, integrating it into a new AR-15 build intended for both range use and potential home defense scenarios. I installed it on the forward M-LOK slot of the handguard to facilitate a two-point sling setup for better rifle control and hands-free carry. The mount was tested in a variety of shooting positions, including standing, kneeling, and prone, to evaluate its comfort and functionality.

The mount performed admirably, securely holding the QD swivel under recoil and during transitions between firing positions. I used it in both dry and slightly damp conditions (early morning dew) and found that the anodized finish provided a good grip, even with mildly wet hands. The installation was straight forward with no issues of loosening or movement during that initial testing period.

The Obsidian Arms QD Sling Mount M-LOK was easy to use right out of the box. The included M-LOK hardware made installation simple, and the QD socket accepted my sling swivel without any issues. No modifications to the M-LOK slot were needed.

Extended Use & Reliability

After several months of regular use, the Obsidian Arms QD Sling Mount M-LOK has proven to be a reliable and durable addition to my AR-15. It has withstood numerous range trips and a few practical carbine courses, showing minimal signs of wear and tear. The black anodized finish has held up well, with only minor scratches from normal use.

There are no signs of loosening or movement on the rail. I periodically check for any potential issues and have found none. Maintenance is incredibly simple; a quick wipe down with a lightly oiled cloth is all that’s needed to keep it in good condition.

Compared to a previous experience with a cheaper, no-name QD mount that eventually failed, the Obsidian Arms QD Sling Mount M-LOK has far exceeded my expectations. The Obsidian Arms mount gives me confidence in its reliability and durability, which is paramount when it comes to critical equipment.
