That looks like a LOT of hammer forged parts! What are you going to do with this tuned masterpiece?
Well, I stripped it down and cleaned it up and threw it back together for now. Whatever kind of magic lube was used on the piston seal, basically dissolved it. It was chalky and falling apart, but appeared to be a modern urethane seal that most guns use. Definitely wasn't lubed with moly paste. Not sure what went on there.
I popped on a cruddy old used piston seal and relubed it to see how it's gonna shoot. Accuracy seems promising so I'll tear it back down and take my time on it later.
My only real beef is with the transfer port, it has been "worked on" from the inside and counterbored fairly deep. It's kinda slammy feeling, probably because the port is effectively bigger. Worst case I'll bore it completely out and press in a sleeve to the size I want. But it won't hurt it the way it is.
The detent wedge has also been heavily "polished" and lockup isn't the sturdiest. But I have a couple spares on hand and will be an easy swap and fix there.
The rest is minor stuff. The crosshacking in the tube luckily isn't on the sealing surface so it won't matter. And I can weld up the piston nose and reshape it if it doesn't want to hold a new seal.
Admittedly I'm pickier than most because I like to work on these things. It would probably be a fine performing gun left as is (minus all the goop).
The R1 definitely isn't my favorite platform, and neither is the .20 caliber. But, it will fill a hole in my pile of guns and I'm glad to have it to play with.
