You'll need a needle too....

Had my 124 tuned by Beeman after a few thousand rounds. Molybdenum disulphide paste in the compression chamber and spring gel made it very smooth and quiet. No need to ever oil the chamber again with the moly. Beeman use to sell Dri-Slide with a needle for chamber lube as well but I don't see it on their website anymore. Had to shake that bottle well, inject a few drops, stroke repeatedly, invert and let the carrier solvent evaporate to preclude dieseling....
