Good buy.
They range from decent rifles, to excellent, even if they look like some of the parts were hacked out of recycled sewer pipe.
If your receiver is new enough to be tapped for scope mounts, I suggest getting a proper scope base for the rifle. I hate the rimfire dovetail mounts altogether, but have seen many of the Marlin X8X series with deformed dovetails, because the rings were overtightened or had to be tightened that far to get the rings to stop moving.
I need to get my own 882 drilled and tapped. I'm tired of the crappy dovetail mount; but mine wasn't drilled and tapped from the factory.
