chasis

Gents, apologies if this has been mentioned, but with regard to the Sage EBR chasis, I believe the mk0, the one with the two bar collapsable stock w/cheek well, do these kits typically come with optic mounting solutions above the chamber? Or is the cantilevered mount which is like another 250...

hello everyone, I have a socom 16 and really liking the cqb stock. Wondering where I can buy the stock? Looked online and only come up with the complete rifle. Does anyone know of a website thats selling them? Also, if I do find one, is it drop in and done? Thanks in advance.
