I ordered a Beeman R9 Goldfinger in .20 cal. from Steve, Pomona Airguns. He does airgun tune-ups but said that I should shoot the gun for a while, It might not need it! Steve said that it would take 50 to 100 shots for the gun to settle down and even talked me out of getting the tune-up done at this time. His cost is $90.00.
I just hope that it is quit and accurate..............LOL
Good Hunting
