Interesting theory. I hadn't thought of that before- I thought they mentioned thread in the video but I'd have to go back and look.
I also imagine folks looking to shave every ounce aren't putting a priority on a suppressor and the added weight, so to your point about wanting a suppressor on yours this might bot be for you.
Im curious about the threads/shoulder now though- maybe they'll release some of those specs soon.
Depends, the suppressor tames down the blast and recoil significantly and makes it shoot like a rifle that weight significantly more. With some of the light weight cans weighing only 8 to 10 oz I personally would take a little extra weight for a much more shootable rifle.
