First Thoughts on the Arisaka 40-Degree Offset Optic Plate 17 – 1913 Adapter
Red dot sights have revolutionized close-quarters shooting, but integrating them with magnified optics has always been a challenge. The Arisaka 40-Degree Offset Optic Plate 17 – 1913 Adapter from Arisaka Defense promises a streamlined solution for mounting a secondary red dot alongside a primary scope. This offset mounting system allows for rapid transitions between magnified and unmagnified views, which is essential in dynamic shooting environments.
I’ve been searching for a better way to run a red dot alongside my LPVO on my AR. The standard 45-degree mounts often felt too far out, affecting my cheek weld and balance.
The Arisaka adapter arrived in simple, no-frills packaging, which aligns with their focus on functionality over flashy aesthetics. My initial impression was positive; the black anodized finish looked clean and durable. It seemed lightweight yet robust, a good sign for something that will be attached to a firearm.
I considered other options like the Scalarworks KICK/01 and the Midwest Industries Offset Mount. I chose the Arisaka for its reputation for quality, modularity within the Arisaka ecosystem, and the promise of a closer-to-bore offset than traditional 45-degree mounts.
I was immediately excited about the potential for a more natural transition between optics, but also slightly concerned about the potential for interference with my existing scope setup.
Real-World Testing: Putting Arisaka 40-Degree Offset Optic Plate 17 – 1913 Adapter to the Test
First Use Experience
I tested the Arisaka 40-Degree Offset Optic Plate 17 – 1913 Adapter at my local outdoor range, primarily focusing on transitioning between my LPVO (Low Power Variable Optic) and a Trijicon RMR. The weather was partly cloudy, around 65 degrees Fahrenheit, with a slight breeze. I practiced drills involving targets at distances from 5 yards out to 50 yards, simulating close-quarters engagements and more extended shots.
The 40-degree offset felt immediately more intuitive than the 45-degree mounts I’d used previously. It required minimal head movement to switch between the scope and red dot. Installation was simple using the provided screws, and it felt solid and secure on my rifle.
The only initial issue was minor: I had to adjust the positioning slightly to ensure the red dot didn’t obscure the scope’s turrets at certain magnifications.
Extended Use & Reliability
After several months of consistent use, including a carbine course and multiple range trips, the Arisaka adapter has held up remarkably well. I’ve noticed no loosening of screws or shifting of the red dot, which is critical for maintaining zero. The anodized finish shows minimal signs of wear, even after being bumped around in my rifle case.
I clean the adapter along with my firearm after each range session, simply wiping it down with a lightly oiled cloth. The Arisaka adapter outperforms other offset mounts I’ve used in terms of stability and ease of transition.
