Picked one up for $90 today, its clean and a .22 so what the heck, right?
Anyone know or have any experience? Looks kind of like a Marlin 60.

Had one back around 1970 I believe. It was second hand and I often got burned powder specs on my arm due to the fit of barrel to receiver. Heard probably caused by a loose nut of some sort. Hopefully you will not have this problem.
The bbl is held to the frame by a collar nut.
The bbl slips into the frame, then the nut which is around the breech end of the bbl is screwed down into the frame and tightened. A shoulder on the nut pulls a matching shoulder on the bbl. The bbl is pulled and locked into position in the frame.
Not meant to be a Quick TakeDown type of system or even one for occasional disassembly by the owner. It was just the way it was designed and put together for the factory assembly line.
A simple press fit bbl shank w/a cross pin seems like it would have been fine like so many other 22's. including that Marlin 60,,but..?
If the assembly is loose, the bbl sits forward & the headspace is way off. Case heads can rupture especially at the firing pin imprint. That's where you get the gas blow back. The entire case heads can fracture too.
A spanner wrench is needed to take the nut off/on. You can make one easily enough by looking at the set-up.
This is seen by taking that metal (or some are plastic) shield cover off of the bbl that is right in front of the rec'vr on top.
To do that, drive the rear sight out of it's dovetail (left to right to take it off) and the cover can be removed.
You'll have to have the forend off and the tube magazine parts off as well to work on the bbl.
Some guns have been tinkered with and the nut has been attempted to be tightened or loosened with a punch and hammer or other gadget means with less than optimum results.
Some are really messed up as far as the wrench slots are concerned. You risk cracking the alloy frame with too much force applied trying to get at the thing.
Some loose bbl fixes in those cases were to Epoxy the bbl into place and hold it back into position clamped steady and straight till the stuff sets.
It wasn't Top Shelf,,but it worked and put the squirrel blaster back in the woods inexpensively.
Replacement bbls used to be available from Numrich. That collar nut is considered a part of the bbl and comes already installed on the bbl as a factory assembly.
Parts were pretty inexpensive as I recall,,but so were the rifles.
