Thread: BSA Ralock - An interesting old semi auto .22

40+ years ago I used to do a lot of work on these. They are built like a brick outhouse but there are also a lot of critical parts made of pressed steel and spring wire. No parts are available (have not been for many years) so take good care of it. They were bad for powder fouling because of the closed breech and brass catching system. Give it a good clean every few hundred rounds and it should serve you well.
