Sturdy plate with lots of mount options - Arisaka Defense Offset Optic Plates

I like the Arisaka offset mount system for it's flexibility. Once you buy the arm you can swap heads to for almost every pistol red dot out there. Support for the 509t's unique footprint was my initial selling point. Recently I switched to the 1.93" height and love the extra elevation. I also switched from 30d to 45d to accomodate a new scope. The switch was easy and the mount does what it should and holds zero thus far.
