First Thoughts on the ARISAKA OFFSET OPTIC PLATE 2 RMR/SRO
The ARISAKA OFFSET OPTIC PLATE 2 RMR/SRO from Arisaka Defense is a seemingly simple but crucial piece of kit for anyone running an offset red dot sight. It’s designed to mate Trijicon RMR, SRO, and Holosun 507C optics to Arisaka Defense’s offset optic mount base. I was particularly interested to see if this plate offered any improvements over the original, especially in terms of mounting stability and ease of installation.
I had been experiencing some issues with my previous offset setup on my AR-15; specifically, maintaining zero on my RMR after moderate use. The optic would shift slightly under recoil, requiring constant readjustment. This was unacceptable for both competition and defensive applications, leading me on the hunt for a more secure and reliable mounting solution.
Upon unboxing, the plate immediately struck me with its clean machining and robust feel. The black hardcoat anodized finish appeared durable and well-applied. It seemed like a solid piece of aluminum. Compared to some cheaper, cast offset plates I’ve used in the past, the ARISAKA OFFSET OPTIC PLATE 2 RMR/SRO exudes quality.
I was choosing between this plate and similar offerings from Scalarworks and Midwest Industries. I ultimately went with Arisaka due to their reputation for precision engineering and the positive reviews specifically mentioning the tight tolerances. My first impression was one of cautious optimism; I was hoping this would solve my zeroing woes and provide a stable platform for my RMR.
Real-World Testing: Putting ARISAKA OFFSET OPTIC PLATE 2 RMR/SRO to the Test
First Use Experience
I first tested the ARISAKA OFFSET OPTIC PLATE 2 RMR/SRO at my local outdoor shooting range on a bright, sunny day. It was mounted on my AR-15 chambered in 5.56 NATO. The installation was straightforward, using the included screws and a torque wrench to ensure proper tension.
The ARISAKA OFFSET OPTIC PLATE 2 RMR/SRO held zero perfectly throughout the first 200 rounds. There were no signs of loosening or shifting. The optic felt firmly secured to the rifle. I even ran a few drills involving quick transitions between my primary optic and the offset RMR, and the plate maintained its integrity without any issues.
Extended Use & Reliability
After several months of regular use, the ARISAKA OFFSET OPTIC PLATE 2 RMR/SRO has proven to be exceptionally reliable. I’ve put approximately 1,500 rounds through the rifle since installing it. It has been exposed to various conditions, including rain, mud, and extreme temperatures, during several training sessions.
The plate exhibits minimal wear and tear. The hardcoat anodized finish has resisted scratches and corrosion. The screws remain tight, and the optic has held zero consistently. This is a significant improvement over my previous experience with less robust offset plates. I clean the mounting plate along with my optic using a microfiber cloth after each range session.

Its greatest strength is its unwavering reliability. I also appreciate the simplicity of the design; it’s easy to install and requires minimal maintenance. There is absolutely nothing that needs improvement.
Design & Ergonomics
The plate’s design is minimalist and functional. The low profile helps to minimize interference with the primary optic. The rounded edges prevent snagging on gear. The lightweight construction does not add unnecessary bulk to the rifle.
The plate is exceptionally easy to install with basic tools and requires no specialized knowledge. The included screws are of high quality. The torque specs are clearly indicated in Arisaka’s instructions.

Maintenance is minimal; simply wipe down the plate with a clean cloth after each use. Occasional re-torquing of the screws may be necessary, but I have yet to do this. The plate is resistant to rust and corrosion, making it suitable for use in humid or marine environments.
Accessories and Customization Options
The ARISAKA OFFSET OPTIC PLATE 2 RMR/SRO itself doesn’t come with many accessories, as its primary function is to adapt a specific optic to the Arisaka mount. However, it unlocks a world of accessory options for your firearm by allowing you to run an offset red dot. This setup can be invaluable for close-quarters engagements or as a backup sighting system.
The plate is designed to work seamlessly with the Arisaka Defense Offset Optic Mount base. It is also compatible with various screws and mounting hardware commonly used with RMR, SRO, and 507C optics. This allows for further customization based on user preference.

Who Should Buy ARISAKA OFFSET OPTIC PLATE 2 RMR/SRO?
The ARISAKA OFFSET OPTIC PLATE 2 RMR/SRO is perfect for competitive shooters, tactical users, and law enforcement professionals who rely on a reliable and accurate offset red dot sight.
