Unless I'm mistaken, B&T has US manufacturers for their designs, at least some of them. B&T USA is listed as being HQ'd in Tampa, so I suppose it couldn't hurt to ask if that particular model is made here. But if they were available in the US, I don't think I'd wanna buy one without knowing how it performed and I can't find anything about 'em.
Maybe because the only country to actively use the M14 is the USA and if nobody in the USA has them... *eyeroll*
