Hi all, ive just bought a BSA International with the prefix F *****H number stamped does anyone know what model this makes it ?. Ive a feeling its a mk5. I tried to fit a simply bipod to its accessary rail which is fitted like a subframe to the barrel and therefore cannot be changed but it will not slide in, is there a simple Anschutz style bipod available for this rifle. While I am on the subject I wish to shoot with a single point sling with an anschutz style ball fitting to the rifle, any ideas please anyone ?
