so they basically said: Oh, well. This thing is so freaking awesome that it shoots rainbows of death and operates on unicorn sweat, cleans itself and might as well have an auto-fired bayonet-harpoon powered by the sheer epicness of the gun itself and the bolt action is so smooth you'd think it was inspired by Casanova's flirts, not to mention the sweet-ass bolt handle which almost moves at your wish, and to top it off, it has a 6 bullet magazine which is 1 bullet more than the standard issue Mauser, and it's so precise it could shoot the left ball off a hamster half a mile away without touching the right one.
Yeah, I guess that's just not the kind of thing Ministry of armaments would be satisfied with, our unicorns just don't sweat enough.
