Hi Andy.
Been looking for years for for capheads,the problem is that the thread pitch on the Anschutz is .075x6mm so I bought a die and cut some blanks I had.
Leave it with me for a couple of day's and I will see if I can find some blank's and make some.
Frank Dyke will probaly get you some, or try the NSRA Shop{About £30 the pair
Regards John F.
