Thread: Rings for Sakos

I have bought a couple of Sakos with my PonyTokens, both of which need rings (25mm). Not being familiar with these things, I see they require a specific sort of ring which I do not possess in my box o' bits. Front and rear different sizes, little doodackey notch (instead of the bar I'm used to) etc..

First one is an A1 Vixen, second is a L579 Forester. Can anyone tell me what the usual go to is? I don't mind forking out for the proper thing, but as I said, all new to me... Learn me up!
