I had my .204 done by Mike Norris he's one of the best riflesmiths in the country . Watch him on YouTube his work is second to none. Excellent service and a very nice guy. Give him a ring and book in click on the link for his number . I booked in with him on a Saturday morning and he did it there and then for me .He takes you into the engineering room and you can watch him do the work. The man's a wizard he also did me a hidden screwcap on the top of my rifle so you can't see that it's been threaded .
