I have the very first 22 lr Carbine barrel for an Encore without an adapter he made. It is marked "Prototype No Adapter". It shoots great, workmanship is excellent. Not having to switch the firing pin block out when changing barrels is great, doesn't take much time to do but it is still nice to not have to. He does some special things to the chamber. I'm sure you won't be disappointed with his products and he is a great guy to deal with.
