Just a question: Why is one of the good points that it's British? Why's that so important? If all you want is more Britishness, then why not just give players tea and crumpets? The AK, katana, Desert Eagle, Benelli(ish) shotgun, SCAR, LAW, Beretta, Winchester, Mac 10, EBR, M79, H&K-based medic gun, and M32 aren't British (having origins in the US for the most part, with the Desert Eagle being Israeli, the katana of Japanese origin, the shotgun and Beretta being Italian the AK being of Russian origin and the M32 being South African), and the crossbow, machete, knife, ax, chainsaw, double-barrel, flame thrower, grenade and pipe bomb not possibly, but not necessarily British (as in Britain has chain saws, but it's not British in identity). The bullpup is really the only weapon that is definitely a British design. A weapon's nationality shouldn't matter, especially since countries adopt plenty of weapons that they are imported.
