I've had a different experience with my Mk2 Service air rifles, which all give excellent accuracy. I was delighted to see scores of 72/75 and 73/75 when I used it for bell target some years ago. One of my Mk2s also won a vintage HFT shoot, beating others using BSAs.

Currently looking for Baikal Makarov pistols with the following prefixes to the serial number: 98, T01, T09, T21, T22
Prefer boxed or cased but will consider loose examples too.
