I think that barrels, trigger units and other bits are made in Brum. Stocks, bar the tactical which is UK made too I believe, are from abroad, and Gamo make other components. BSA assembles them (except the Meteor 7 which is Gamo assembled???). The PCPs are certainly put together in the UK but some parts may come from elsewhere. Its like any company these days, parts come form all over. I think, if you look in the potted history of BSA they have on their website you will find the Gamo takeover listed. Still a lot going on at BSA.
