Yay or nay? I'm considering an AX/R700 .308 build and I'd like to hear from those familiar with the AX chassis. Are the mags proprietary or can standard aftermarket aics mags be used? Does the stock lock up solid? Likes/dislikes/caveats? The rifle will be used mostly for prone off bipod/bags as well as positional shooting with a sling. Mainly shooting steel with occasional paper targets depending on what I feel like that day. Shorter barrel and modest ranges. Not looking for competetive 900m performance just a fun LR setup.
