Axel,
Well done all on there.
That at least gives everybody a fair look at a great gun.
Clearly without looking at it, and not knowing what you have with it, other than a good M14mag and a normal magazine supplied, it is £5500 GBP any day of the week, especially as it was bought originally by the German
Army. Do you have the carrycase too?
Good Luck it will sell as the rifle has its own pedigree and not many made.
