I like my vision Chassis, but I don't love it. I have not found a chassis that I love, so for now I'm sticking with it.
I don't like the barricade stop in front of the mag well. It wouldn't be bad at all if the chassis wasn't so rear heavy, it's a bit difficult to get the center of gravity far enough forward of the barricade stop.
This could be addressed by changing the midsection to remove or relocate the barricade stop, lightening the rear of the chassis, or a combination of both, but right now there aren't options to either (not including DIY).
I have a 26" proof comp contour barrel and a supercal bipod hanging off the chassis and I could still use more weight out front. The barricade stop location prevents this chassis from being used in all but the heaviest of setups, which for me is a disappointment, but it's a PRS stock and weight is seen as a good thing generally.
I also think the magazine well isn't the easiest to work with, it's tight and the spring is very stiff so magazines don't slide in easily the way they do on my manners. I think that's an easy fix though, just need a softer spring for the mag release.
Vision has recently made some changes to the butt pad and cheek piece that I like. It's just that barricade stop on some of the chassis' that needs to be addressed, the KRG and AI forends don't have this "feature", so its a bit annoying to have to deal with it on the r700 chassis.
Other than that, it's a fantastic piece of kit. The manufacturing is high quality, there are many options for weights and rails for the forend and the adjustability of the buttstock is fantastic. It's an expensive chassis and options can really push the cost even higher, but if you don't mind the price (or the barricade stop), it's certainly one of the nicer options on the market (IMO).
