Looking good. I have a Bugbuster side focus on my Xisico XS-25 and I love it. I have the sunscreen and flip up caps on mine. I think you'll like it.
It's holding zero well. 4th time I've shot it since mounting the scope. First time on paper since. First thing in the morning. I've been hitting all the metal targets & just wanted to see. I think this was 6 shots. 50yrds. Crosman hollow point. I could have done better but this is shooting as fast as possible
