Remington Model 24
It is a takedown gun, meaning that the barrel and receiver are easily separated without tools, allowing for a smaller package for transport.A case deflector (seen in the image here) that hooked into the receiver and clipped onto the trigger guard was available.In this photo of John Browning [1] a close look will reveal that he appears to be holding a Remington Model 24 semi-automatic .22 rifle.The Model 24 uses a barrel tightening method (needed due to the takedown nature of the design in which the barrel can be separated from the receiver) that is very close to that of the Browning SA-22.That tightening method uses an adjusting ring on the lower end of the barrel where it presses up against the receiver.
