Currently own a Christensen Arms Ridgeline. Recently went to a long range shooting school and got me thinking that I’d really like an adjustable length of pull, adjustable cheek riser. Been looking at some options out there and am wondering what people think about light weight chassis? I don’t want to compromise accuracy and would like to keep the weight as close to my current ridgeline as possible. Accuracy in a chassis vs. traditional stock? Any thoughts on MPR chassis by Christensen or the ultralight chassis by MPA?
