I apologies if you didn’t understand my comment. I work with it daily so I have some background info and forget that others don’t.
There is no standard called Arca, there is no company called Arca, in what meaning I am referring too. “ARCA” has just become a common term for a type of rail.
Arca-Swiss makes a lot of camera products along with some plates, alot of companies and other photographers make plates the have a Dovetail built in. The problem is they use different angles and different widths without documenting what they use. RRS has been making plates with a dovetail for 27 years and we are finally trying to standardize it and have it open source so everyone can use it.
My issue was we start helping out the industry with more more and more products, then it gets adopted by the industry, cool right? The problem is is if someone takes the exact specs we put on the web, then they call it a different name, people start thinking they are the same thing. So people like me who talk to shooters pick up a call when someone bought a arca plate off line and install their bipod, recoil made the bipod jump off the end and the user almost shoots his son in the leg with the second round from semi auto. I am just trying to let others know.
No overtones of entitlement but if you you want to think that way I can’t stop you. I am not a writer so I hope my point can come through over text. If not feel free to call me, Michael
805-548-1534 I’m back in the office the 2nd and I’ll explain my reasoning and the premis behind it.
Arca is simply becoming a common term, sucks but whatever. I don’t want you guys to assume every dovetail is the same spec and entrust your rifles withit just because others in the industry use it. If you can, please use safety stops so nothing happens in worst case scenario like “guy above”.
