Trijicon RMR Mount for ACOG without Bosses Review

One Month Later: Trijicon RMR Mount for ACOG without Bosses Review

The Trijicon RMR Mount for ACOG without Bosses is a critical accessory for any ACOG owner looking to add a secondary, close-quarters red dot optic without sacrificing the primary scope’s capabilities. Machined from aircraft-grade aluminum, this mount promises a robust and lightweight solution for integrating your Trijicon RMR onto compatible ACOG models. It’s designed to bridge the gap for those who need the versatility of both a magnified optic and a fast-acquisition red dot sight.

My own setup was feeling increasingly limited. While my trusty ACOG provided superb magnification for distance, transitioning to close-in engagements felt clumsy and slow, especially in dynamic scenarios where milliseconds matter. I needed a way to augment my primary optic without compromising its established performance or adding excessive bulk. After researching solutions, this specific mount emerged as the most direct and purpose-built option for my setup. I had briefly considered more universal rail adapters, but the potential for added height and less elegant integration pushed me towards a dedicated solution. My initial impression upon receiving it was positive; the aluminum felt solid, and the finish was consistent with Trijicon’s reputation for quality.

Real-World Testing: Putting Trijicon RMR Mount for ACOG without Bosses to the Test

First Use Experience

My testing primarily took place on my personal AR-15 platform, used for a mix of recreational shooting at a local range and occasional participation in informal carbine courses. The installation was straightforward, requiring basic tools to secure the two pieces of the mount to my ACOG and then attach the RMR. The included screws were of good quality, and I appreciated that they were precisely sized for their intended purpose. In terms of environmental exposure, it endured a typical range day with no issues, and I experienced no performance degradation when transitioning between different target distances.

The ease of use was a significant plus. Once mounted, the RMR sat securely, and the transition from magnified view to red dot acquisition felt natural and quick. There were no immediate surprises or quirks; the mount simply did its job as advertised, providing a stable platform for the RMR.

Extended Use & Reliability

After a solid month of consistent use, this optic mount has proven its worth. It has been mounted and dismounted a few times for accessory changes, and the mounting points still feel as secure as they did on day one. The aircraft-grade aluminum has shown no signs of stress or deformation, even after being torqued down appropriately.

Durability has been excellent. I haven’t observed any significant wear, such as cracks, excessive scuffing, or stiffness in the mounting mechanism. Its simple, two-piece design means there are very few potential failure points. Maintenance has been minimal; a quick wipe-down with a dry cloth to remove dust is all that’s typically required. Compared to some generic or less robust mounting solutions I’ve used in the past, this Trijicon mount feels considerably more substantial and reliable. It doesn’t exhibit the slight flex or looseness that can sometimes plague less expensive alternatives.

Breaking Down the Features of Trijicon RMR Mount for ACOG without Bosses

Specifications

This mount is specifically engineered for Trijicon’s ACOG line, designed to fit ACOG models without bosses. Its construction relies on aircraft-grade aluminum, a material chosen for its excellent strength-to-weight ratio. This ensures the mount is both lightweight, minimizing added bulk to your rifle, and exceptionally rugged, capable of withstanding the rigors of field use. The mount features a simple two-piece construction, which contributes to its straightforward installation and inherent stability. It includes the necessary screws for proper installation of both the mount onto the ACOG and the RMR onto the mount. Furthermore, there’s a pre-drilled hole designed to align with the mounting interface of an RMR or Trijicon’s own ACOG Mount VGA.

The use of aircraft-grade aluminum means this mount is built to last, providing a dependable platform for your RMR without adding unnecessary heft. The two-piece design simplifies the mounting process, making it accessible even for those less experienced with firearm accessories. The inclusion of all required hardware is a practical consideration, ensuring you can get your setup operational right out of the box. Finally, the compatibility with the RMR footprint and the VGA mount ensures a secure and precise fit for your secondary optic.

Performance & Functionality

The primary function of this mount is to enable the secure attachment of a Trijicon RMR red dot sight onto an ACOG scope that lacks integrated bosses. It performs this task exceptionally well, offering a stable and repeatable mounting surface. The resulting setup allows for rapid target acquisition at close ranges while keeping the primary magnified optic functional for medium to longer distances.

• Strengths: The ability to seamlessly integrate an RMR onto specific ACOG models is its greatest strength. It provides a rock-solid platform that doesn’t shift or loosen with recoil. The elevation provided by the mount is generally well-considered, bringing the RMR to a usable height when paired with the ACOG.
• Weaknesses: The major limitation, inherent to its design, is its strict compatibility requirement. It will only work on ACOG models specifically designed without bosses, which can be a point of confusion if not carefully checked. This isn’t a fault of the mount itself, but a critical purchasing consideration.

Design & Ergonomics

The design is purposefully utilitarian, focusing on function over aesthetics. The black finish is matte and non-reflective, which is ideal for tactical or practical use where minimizing glare is important. The material, aircraft-grade aluminum, gives it a solid and premium feel, despite its relatively simple construction.

Ergonomically, the mount is designed to be installed and then largely left alone. Its main contribution to ergonomics is facilitating a more natural transition between sighting methods. The clean lines and lack of protruding parts mean it doesn’t snag on gear or create awkward handling issues. The pre-drilled hole for RMR mounting also ensures the optic sits flush and is properly seated.

Durability & Maintenance

Built from aircraft-grade aluminum, this mount is designed for long-term durability in demanding environments. It’s not a disposable item; it’s engineered to be a permanent addition to your optic setup, capable of enduring thousands of rounds of recoil.

Maintenance is virtually non-existent beyond basic cleaning. The aluminum construction is resistant to corrosion, and the black finish is durable enough to resist minor abrasions. There are no intricate mechanisms or moving parts to worry about, making it an incredibly low-maintenance accessory. Potential failure points would likely stem from overtightening screws or extreme physical damage, neither of which is typical for this type of equipment.

Accessories and Customization Options

This specific product is primarily a mounting solution and doesn’t come with many accessories beyond the necessary screws for installation. Its customization lies in the optic it attaches – the Trijicon RMR red dot sight. The mount is designed to mate perfectly with the RMR footprint, ensuring a secure and precise fit. It’s also noted to be compatible with the Trijicon ACOG Mount VGA, suggesting a modular approach within Trijicon’s ecosystem.

While not a customizable component in itself, its purpose is to enable customization of the ACOG platform by adding a secondary sighting system. The choice of RMR model (e.g., different reticle options, automatic vs. manual brightness) is where the user’s personalization comes into play.
