OK, pulled it apart and the stock ready to use is 2.1 lbs. and the whole rifle scoped, slung, and ready to hunt with (except an MT mag, wasn't going to load it in my garage), weighs 6.9 lbs. So not an ultralight, but all together its under $750 so not an ultralight price either. Or rather the price is pretty "light" & not in the normal range of a custom built ultralight. I found a page called "titainium fasteners dot com:" or similar and the stocked M6X1.0 Ti Torx Button Heads in the two lengths that I needed, so I saved an ounce, maybe two there. Easily the highest price per pound parts involved, but why not? LOL
Hollowed forearm; the AL block connects both flush swivels in the sides of the forearm with the traditional stud for bipod use, can also see the AL pillar and the divot in the bedding that I still need to fix:
The hollwed butt; the glued-in plug fixes where the pad screw wanted to break out and is only ~.50" long:
How deep the hollowing goes:
Proof, such as it is. This is really at the very bottom end of the scale's range, that it was a tenth or two off wouldn't surprise me.
