Just got my Arisaka and after install it looks like a screwed in plate is likely not gonna work. I really hate going in another direction bc I already have the IWC but if I end up using an Agency forearm I might as well use it to mount the light and switch. My finger still hits the QD cup and that would fix everything. Ughh, I used to love experimenting but back then I wasn’t married and had more $$. This thing is becoming a money pit, lol! For now it’s gonna be the end cap switch till I decide to get stupid and buy the Agency.
