I don't know if you've ever seen T+T, but all of the rifles clip and go through the shoulder and it looks fine.
Maybe you should look again, and feel free to post pictures to prove me wrong. and fyi, tier tactical may be good but Bushido definitely got a bit lazy.
and I'm not saying a little clipping is awful, but the stock of that gun will be 2 brick lengths behind the Blockhead holding it
