Tuning Recommend a Repairman

Scott aka Motorhead

I have one gun that has been tuned by him. Knowledgeable and honest guy. I appreciate honesty far above anything else.

I would also recommend Martin Rutterford, https://www.airguns-usa.com/, neighbor of David Slade and fellow Englishman. Although best known as the maker of RAW air rifles, he now operates a custom shop where he does other work. Honest, capable, and easy to work with. He is in TN, and as you are in CA, you might prefer Scott, with whom I've done business and recommend also.

Martin is indeed outstanding and does know the AA rifles through & through including custom parts.

 Straight Shooters(great customer service) gave me the phone number of several repair shops for my Air Arms s410 rifle. I made a phone call to David Slade at Airgunwerks. He personally answered the phone and was very helpful and forthcoming with pertinent information, especially about how to ship it safely. So, my gun is now on it's way to be rejuvenated. I'm keeping my fingers crossed and hoping I see it back on my doorstep before Christmas. Until its return, I'll be down to just the one springer- RWS 54.
