I've got one of the GSG Sturmgewehrs as well. Love it. Mind, I've been around long enough to have owned one in 7.9 x 33 that worked (pre-Dunblane) albeit the selector lever had to be welded to self-loading (& safe) only. Our late treasurer who was a '2 sighters & 10 to count' man (he never shot more than twelve rounds per shoot - why could one possibly want a rifle with a magazine?!?) went very quiet very quickly when a pal of mine shot five bulls in five shots at 300 with it.

Sorry.....wandered off topic a little. Apols.
