Anyone using Sports Match rings ?

[Brewster20]

Anyone here using "Sportsmatch" rings made in U.K. ? I've been looking for some 11mm dovetail mounts in 30mm tube (CZ) and came across these:

I have a one pc sports match mount on my air rifle. Only complaint is its fugly.

I also have a pair on my air rifle - one piece adjustable.

I also think they work well, but are fugly.
