I've a pair of 25mm rings gloss bought from bewsher a couple of weeks back but unfortunately they dont clear my scope (maybe suit a 44mm etc ) measures approx 12.5mm from top of dovetail to bottom of ring. £25 posted.
Also a pair of 30mm matte rings (possibly millet) that the rifle came with, measues approx 16.5mm from top of dovetail to bottom of ring. £25 posted.
These came off a fox model 2 and I believe they will fit most rimfire and sub .223 cz/brno rifles but please check.
I can't upload the photo of them but I can email to anyone who is interested. Atb
