Lee (Shootist) tuned both my Diana 34 and my HW50S. I am well pleased with his work and his work ethic. Lee stayed in constant contact and kept me informed of each step throughout the process on both guns. He even replaced the rear sight on my Diana which was broken in transit due to my poor packing.
I'm considering purchasing another air rifle from Krale Schietsport in the Netherlands. I was so pleased with my first purchase from Krale and Lee's work on my Diana 34 and HW50S, that I may just have Krale drop ship the new gun to Lee to be tuned before I see it.
