First day out with the recently purchased CZ452 Lux (wanted an Ultra, but couldn't find one). I was only able to shoot at 25yards indoors. From a makeshift bench I was able to regularly get sub 1" groups at 25 yards with the excellent iron sights (Mauser type, adjustable for windage and elevation). Offhand I was able to hit a 1" Shoot'N'C regulary. I didn't have any plans to mount a scope, but I may have to in order to see what this baby can really do. Fit and finish is excellent. I will have to check the barrel channel in case any sanding is required, but it shoots really great right now. trigger was good as well, a little creep, but nothing of a hindrance. If anyone is looking for a great .22 with iron sights, I would recommend the Lux. Shoots as good or better than my FrankenRuger and cost significantly less. Wow!..I am impressed.
