I have an Avenger Bullpup with three bumps inside the barrel near the breech, resulting from the drilling of the outside dimples for the set screws. I never noticed them until well after the warranty was up. It shoots pretty well, but I've been thinking about getting a Lothar Walther barrel blank and finding someone to turn the breech diameter down and machine the o-ring grooves and drill the transfer port, as described in this post: https://www.airgunnation.com/threads/new-25-avenger-barrel.1280410/

Is this something you would be interested in doing?

I would assume that you might also be enabled to make a piston cylinder similar (but not exact) to the ones used for a Shoebox?
Made of aluminum (don't know the exact material). The original manufacturer no longer produces these and only used ones are rarely found (if any). Stopped production around 2016. I have one that is damaged and need one to replace it.

That would be a very simple job. I looked at the thread to get an idea of what's done and I can promise my machine work looks much better than what that individual got back. Not trying to be mean but honest.

Do you have the damaged one that I could copy? If so I can make it.

That sounds great! I'm not sure what the forum rules are about conducting business on these public forums, but I would like to discuss this with you. I don't have enough posts to initiate a private message conversation, but I can reply if you PM me. Please send me a PM and we can talk about it. Thanks.
