A lot of Chassis can add significant weight, depending. I also have a KRG Bravo and really like it. I’ve added the adjustable buttstock to it - cant and length and an ARCA rail for shooting off a tripod. I really like it’s fit and feel - though mines not light with the 5-25x50 I’ve got on it.
I have an Sig cross that I really like too. Much lighter and more compact. It has a more typical metal chassis with folding stock. However, it is cold on the hands in winter and can make that annoying metal ring when it bangs up against things. I’ve found I prefer a more traditional rifle stock though with a fairly vertical grip that is comfortable prone as well as offhand.
I’ve always liked the look and feel of the GRS stocks. Not a chassis, but adjustable cheek piece and length of pull and comes in great looking, warm laminates.
