Ive been on a journey trying to outfit my 300 prc with a chassis system that takes AICS Mags and was a folder. MPA Seems to fit the bill with the ultra lite. Anyone have anything good or bad to say. I know XLR has the element 3.0 but im not sold on it, their folder locking mechanism is kinda subpar. Ive been useing KRG W3 chassis and also have an AX which are by far my favorite chassis that i can consistently get behind and shoot well. But the goal of this rifle is to be under 10lbs since i plan to carry/ pack in rough terrain for many miles and days. Appreciate the input.
