Re: sonix eye install
it's a lot of work, but you can do it yourself if you have the tools and the know how. I don't think kingman does that, at least I've never heard of anyone getting that done there.
Honestly, I'd either A. get a fast and reliable force feed hopper or B. (if you really want eyes) buy a marker that has eyes. There's no cheap way to install eyes on it that wont make it look ghetto
