Real-World Testing: Putting Evolution Gun Works Universal Trijicon RMR Sight Mount, 1.780 in, Aluminum to the Test
First Use Experience
My initial deployment of this EGW mount was on a recent AR-15 build intended for general-purpose use, balancing range time with some informal carbine courses. The testing grounds were a familiar outdoor range, subjected to the typical conditions of varying light, a moderate amount of dust kicked up from the firing line, and the constant, sharp impulse of live fire. Installation was straightforward; the 2x 6-32 Flat Head Screws provided a secure primary hold, and the 1x 6-32 Set Screw offered an invaluable secondary point of tension.
The mount’s bottom radius of .468″ was designed to accommodate a range of receiver diameters, from .936″ to 1.350″, and I was pleased to find it seated snugly on my chosen upper receiver. The specified slight gap at the top of the radius, as described in the product details, is a thoughtful design element that accounts for minor manufacturing tolerances, ensuring a firm clamp without over-stressing the receiver. The Trijicon RMR I mounted onto it felt locked in place, with no perceivable wobble or flex during the initial sighting-in process.
No significant issues arose during this initial fitting and zeroing. The matte black finish remained consistent and resisted minor handling marks. The true test, however, would be its performance under sustained fire and environmental exposure.
Extended Use & Reliability
Weeks turned into months, and this EGW mount transitioned from a new component to a reliable fixture on my carbine. It has endured hundreds of rounds, ranging from rapid-fire drills that generate significant heat to slower, deliberate shots during precision practice. It’s also been exposed to a light rain shower during an unexpected downpour and accumulated its fair share of workshop dust while the firearm was disassembled for cleaning.
Durability has been impressive. There are no visible cracks, no looseness developing in the mounting points, and the 7075 Aluminum construction has held up remarkably well. The Matte Black Hardcoat finish continues to resist scuffing, even when the firearm has been leaned against benches or stored in a padded case alongside other gear. Performance hasn’t degraded; my red dot optic maintains its zero shot after shot, a testament to the mount’s stability.
Maintenance is refreshingly simple. A quick wipe-down with a microfiber cloth and a mild solvent is all that’s typically needed to keep it clean. The screws remain tight, though I do a periodic check as part of routine firearm maintenance. Compared to some previous experiences with less robust mounts that developed play after a few hundred rounds or required constant retightening, this EGW unit has been a revelation in its low-maintenance, high-reliability performance. It certainly outperforms many of the budget options I’ve dabbled with, and it holds its own against some mid-tier offerings.
