I'm not a high volume consumer of Crosman parts, but every Crosman owner needs "stuff.". It's just part of the addiction. I generally get mine from Alchemy's Needful Things Ebay store. I am always pleased with the quality and service. Yesterday I found I had gotten a defective barrel and sent an Ebay message about it. Within an hour, David called me to say he was immediately sending a. replacement. This was a small purchase from a small consumer and he went to the trouble to find my phone number and call me. He's serious about what he does and I appreciate it.
