First Thoughts on the KDG SIDELOK TRIJICON RMR LOW MOUNT
The KDG SIDELOK TRIJICON RMR LOW MOUNT from Kinetic Development Group, LLC promises a robust and reliable mounting solution for the ever-popular Trijicon RMR. This low mount aims to provide a secure and repeatable zero for red dot sights on various firearm platforms. I was intrigued by the SIDELOK’s reputation for quick detach and return-to-zero capabilities, something crucial for maintaining accuracy when switching optics.
I was in the market for a lower-profile RMR mount for my pistol build, something that would co-witness with suppressor height sights and maintain a sleek profile. I had previously been using a standard Picatinny rail adapter, but it added unnecessary height and bulk. The KDG SIDELOK system seemed like a more streamlined and potentially more rugged solution.
Upon unboxing, the KDG SIDELOK immediately impressed me with its robust construction. The black finish was even and seemed durable, and the mount felt solid in my hand. The machining was clean and precise, giving the impression of a high-quality piece of kit.
Compared to a standard Picatinny RMR mount and a direct-milled slide, the KDG SIDELOK offered a balance between versatility and low profile. While a direct-milled slide offers the absolute lowest mounting option, it lacks the ability to easily swap optics between firearms. The KDG SIDELOK, on the other hand, provides a QD (Quick Detach) solution while still maintaining a significantly lower profile than a traditional Picatinny adapter.
My initial impression was one of cautious optimism. The build quality was certainly there, but the real test would be how well it held zero under recoil and how easy it was to use the SIDELOK quick detach mechanism. I was eager to get it to the range and put it through its paces.
Real-World Testing: Putting KDG SIDELOK TRIJICON RMR LOW MOUNT to the Test
First Use Experience
I first tested the KDG SIDELOK at an outdoor shooting range, mounting it on my Glock 19 MOS with a Trijicon RMR Type 2. The weather was dry and mild, perfect for an initial zeroing and function test. Mounting the RMR to the SIDELOK base was straightforward, and the provided screws were of good quality.
The SIDELOK mechanism itself was intuitive to use, requiring a firm press to lock and unlock. After zeroing the RMR, I removed and reattached the mount several times. I was pleased to see that the return to zero was remarkably consistent, with only minor adjustments needed after each reattachment.
There were no immediate issues or surprises during the first range session. The low profile of the mount was immediately noticeable, providing a much better cheek weld and sight picture compared to my previous setup. The robust locking mechanism instilled confidence in its ability to hold zero under recoil.
Extended Use & Reliability
After several months of regular use, including weekly range trips and participation in a local pistol competition, the KDG SIDELOK has proven to be a reliable and durable mounting solution. I’ve put several hundred rounds through my Glock with the RMR mounted on the SIDELOK, and it hasn’t budged. There were no signs of loosening or shifting.
The finish has held up remarkably well, with only minor wear marks visible around the locking lever. Cleaning the mount is simple; a quick wipe down with a lightly oiled cloth is all it takes to remove any powder residue. The QD mechanism continues to function smoothly and reliably, even after repeated use.
Compared to my previous Picatinny adapter, the KDG SIDELOK has significantly improved my shooting experience. The lower profile provides a more natural and comfortable shooting position, and the quick detach capability allows me to easily switch between optics without compromising accuracy. It has definitely exceeded my expectations.
