Thanks but I think the rings are too big.

6 yards are like 10m targets but only the 7-10rings are black, so you get a good sight picture with diopter sights, as appears to 10m targets where the 4-10 rings are black and they are too big at 6 yds.

These guys sell sensible amounts but they’re closed at the mo an me & the missus want to do some lockdown practice indoors with a couple of Feinwerkbau’s.
