I have a mint mk1 (bought from here).

They really are a childs rifle - I am only small 5'6" but I "loom" over it and it is awkward to aim as even my small arms are too long.

That said it is a cracking little gun and accurate. Mechanically it seems a little frail so I do take great care when using it.

If I was going for another one I'd get a rough example and just enjoy using it without the worry of marking it.
