10 years ago I had a MK 1 12/200 .20cal with an ambidextrous stock on it and I've got to say they are fantastic hunting machines. They knock spots off all the BSA's Webley's, Air Arms etc etc out there on the market. I've ordered the S-TYPE in .177 last week and it should be with me in 2 weeks from tomorrow.
How do you find your Theoben MK 1 to use? And what caliber is it you are using?
