Seems to me to be a lot of unjustified "BSA bashing" in this thread. I rather hoped that people on this forum had more brains than that.

FWIW, I have a couple of BSA rifles & have owned several more, & I've never had an issue with accuracy in any of them. In fact, an ancient Mercury that came to me as a wreck is the most consistent rifle I've ever seen and shoots very well indeed.
And the nitpicking about how a barrel is attached to the support/breech block is pointless. Any means of attaching metal to metal involves some kind of process that will cause deformation to some degree.
