Remington Model 241


The Remington Arms Model 241 Speedmaster, an autoloading rimfire rifle, was manufactured from 1935 to 1951 from a John Browning design. Remington reports that 107,345 rifles were manufactured in.22 Short or.22 Long Rifle. A similar rifle is currently being sold by Browning Arms Company.
The Remington Model 241 is a takedown design in which the barrel can be easily separated from the receiver to shorten the rifle's length for ease in transporting.
When Remington brought out the Model 241 in 1935 it replaced the Model 24 which, although of slightly smaller size, was also based on John Browning's semi-automatic.22 rifle design.
The Remington Model 241 is very similar to the Browning SA-22 with the significant difference being the way in which the barrels are adjusted so that they fit snuggly against the receivers when the rifles are fully assembled. This barrel tightening feature is made necessary due to their takedown designs.
Whereas the Browning SA-22's barrel tightening is accomplished with an adjusting ring at the base of the barrel where it butts up against the receiver - the Remington Model 241's barrel tightening mechanism uses a dual-sided nut riding inside the threaded hole in the front of the receiver. Selecting how deeply the dual-sided nut sits in the receiver controls how tightly the barrel fits against the receiver when it is attached.
Persons wishing to make adjustments to the Model 241's barrel tightening mechanism must become familiar not only with the use of the dual-sided nut but also how that nut is locked in-place. What appears to be a flat blade screw head on the right side of the Model 241's receiver, that can easily be mistaken as a screw to lock the dual-sided nut in place, is actually a cosmetic affectation on what has sometimes been described as a 'slug'. While the slug does indeed press against the outside of the dual-sided nut it does not have its pressure against the outside of the dual-sided nut adjusted by rotating but instead the slug is held pressing against the outside of the dual-sided nut by first being simply pushed against the outside of the dual-sided nut and then a screw presses against the side of the slug and thus prevents it from moving. That locking-screw is oriented such that it comes in from the direction of the front face of the receiver.
To adjust the Model 241's barrel tightness it is necessary to first loosen the dual-sided nut so that it can rotate and thus have its depth within the receiver changed. To loosen the dual-sided nut requires that the 'slug' pressing against it be loosened and to accomplish that the locking-screw must be backed-out so that it isn't pressing against the slug. The slug is then jiggled and that will be sufficient so that the slug disengages from the outside of the dual-sided nut. The Model 241's elegant barrel tightening mechanism can be damaged if these steps are not followed.
