Unsure of what you are asking exactly. Micro-groove is a term used by Marlin to denote a type of rifling in its barrels. If you are asking if such a barrel can be tightened to the receiver (frame) of the rifle, the answer is maybe. Some are threaded, some are held by a cross pin, and some are a press fit (under great pressure). With any of the methods, you may change the headspace of the cartridge by changing barrel-to-receiver, and that CAN be a very dangerous condition. IF your barrel is loose, this should go to a gunsmith. Soon.
My Glenfield Model 25 has a micro-groove barrel,so I imagine others do as well.
Not necessarily.
