Me too, but on my UV BL (so not the rubber version) they where loose and i lost one while walking here along the river. I noticed it when i came home, put the remaining objective cover “somewhere”. Two weeks later i found the lost one during my daily walk but now i can’t find the other one
Right, Opticron objective cover #31086 is a bit loose on the UV 8x20 BR. It's way too loose IMO for the BL version. It fits the Curio a bit better and works on the UV 10x25 BR as well.
I haven't found anything commercially available that's more suitable for the BR or BL. 3D printing may be the only option.
