I believe importing barrels from Europe is either against their export law or so cost prohibitive that it's not worth it. I remember a poster who mentioned there was a machinist over there (possibly in Denmark?) who would sell barrel extensions that you could use with a standard rifle barrel to fit the SSG3k action. Border barrels might also be able to help you with this. I haven't seen any STR-200 stocks, but if you are interested you can ring up McMillan and have them make their SSG stock for you. It is a variant of the A-3 with an adjustable cheek, spacer system, Anschutz rail, and sling studs. Runs about $900.
