The 3x9x50 is superb, my old boy has one on his Falcom will a mil dot ret I think he paid about £50 for it! I've got a 6x24x50 on my .22 HW100 and it's not missed a beat. It's not as clear close up as my MTC Viper but I wouldn't swap it and for £70 I'm well happy. Mine has finger adjustable targets and you can change the reading to zero, which helps when I'm letting others use my gun!
