Finally got the BRNO sights on the UltraLux today, with pictures below. I have to say, the BRNO target sight photos thread on rimfirecentral was very helpful, particularly the photo of the modified screwdriver to seat the nut holding the front sight to the ramp. I did exactly that with a Dremel tool and it worked great, whole thing only took 10-15 minutes.

Took the gun down to the club tonight, but also had Sophia with me trying her new 22 as well, so I only got to shoot a couple of targets with the new sights, but I was in and around the black pretty quickly. Offhand didn't seem to difficult at all, and first three sighters off the bench went into a single hole--that got me pretty cranked up.
