I’ve just had to buy a 1” high (adjustable) 30mm set (pretty much identical except they’re in black ) for that Yukon Photon that I bought last year, I got them on eBay for £16 including postage from China. As much as I dislike the idea of buying Chinese I really can’t fault them. I’ve just had the photon out on the chalet park on the other side of the river and took a dozen bunnies in just over an hour…including chatting with the site manager.
There wasn’t quite enough movement without the screen looking weird and off centre. It was fine on the 22lr at 100yrds but with the air rifle at 40yards I couldn’t get point of aim and point of impact closer than 10”
