ARISAKA DEFENSE Offset Plate, Holosun 407k & 507k For 1.5”- 1.8” Scope Mount Review

The ARISAKA DEFENSE Offset Plate, Holosun 407k & 507k For 1.5”- 1.8” Scope Mount Made a Bold First Impression

The ARISAKA DEFENSE Offset Plate, Holosun 407k & 507k For 1.5”- 1.8” Scope Mount is a seemingly simple, yet potentially game-changing piece of kit designed to allow the mounting of a Holosun 407k or 507k red dot sight in an offset position on rifles with 1.5”-1.8” scope mounts. Designed and manufactured by Arisaka Defense, it promises to provide a rapid transition between magnified optics and a close-quarters red dot. This tiny plate, retailing for around $23.49, could potentially solve a significant tactical problem, or be just another piece of unnecessary hardware.

My journey to finding this offset plate stemmed from a need for versatility in my AR-15 platform. While I love the precision of a magnified scope for longer-range engagements, the transition to close-quarters targets always felt clunky, requiring awkward adjustments or reliance on less-than-ideal holdovers. I needed a solution that would allow me to maintain speed and accuracy regardless of distance.

Upon unboxing the ARISAKA DEFENSE Offset Plate, I was immediately struck by its minimalist design and seemingly robust construction. The black finish was clean and even, and the plate itself felt solid in my hand. It didn’t come with any fancy packaging or included tools; just the plate itself, relying on the user to have the necessary hardware for installation.

Compared to other offset mounting solutions I’ve considered – primarily those involving more complex and bulky mounts that attach directly to the rail – the Arisaka Defense option seemed far more streamlined and less prone to snagging. The simplicity of the design was a major selling point, hinting at a potentially more rugged and reliable system. My initial impression was cautiously optimistic. This little plate might just be the answer I’d been searching for.

Real-World Testing: Putting ARISAKA DEFENSE Offset Plate, Holosun 407k & 507k For 1.5”- 1.8” Scope Mount to the Test

First Use Experience

My first test of the ARISAKA DEFENSE Offset Plate took place at my local shooting range, mounted on my AR-15 with a 1-6x LPVO and a Holosun 507k. The range offered a variety of distances, allowing me to evaluate the transition between optics at varying target ranges. I specifically focused on drills that involved engaging targets at 100 yards with the scope, then rapidly transitioning to targets within 25 yards using the offset red dot.

The plate performed admirably even after being subject to a variety of adverse weather. Though it was not raining when initially sighting in the offset red dot, a sudden downpour quickly appeared while practicing transitions. The Holosun 507k was quickly covered in water, the ARISAKA DEFENSE Offset Plate provided me with a solid base and allowed me to continue testing, even in the poor weather conditions.

The initial learning curve involved adjusting my grip and head position to quickly acquire the red dot. After a few magazines, the transition became much more fluid, and I found myself engaging close-quarters targets with significantly improved speed and accuracy compared to using the magnified optic. There were no immediate issues with the plate itself; it remained securely attached to the scope mount, and the Holosun 507k held zero.

Extended Use & Reliability

After several months of regular use, including participation in a couple of local shooting competitions, the ARISAKA DEFENSE Offset Plate has proven to be a reliable and valuable addition to my setup. It has held up well to the recoil of my AR-15, showing no signs of loosening or shifting, and the black finish has resisted scratches and wear despite being exposed to the elements and frequent handling. Maintenance has been virtually non-existent, requiring only an occasional wipe-down with a clean cloth.

Compared to previous attempts at utilizing offset optics – I had experimented with a bulkier, rail-mounted system that added significant weight and felt cumbersome – the ARISAKA DEFENSE solution is a clear winner. Its low profile and lightweight design make it almost unnoticeable during normal use, while its robust construction inspires confidence in its long-term durability. It has definitely outperformed my expectations, providing a streamlined and reliable way to transition between magnified and unmagnified optics.
