Marlin M-375: A proof of excellence

Marlin M-375 lever-action rifle

Marlin M-375 is a lever-action rifle chambered in .375 Winchester caliber and manufactured by Marlin Firearms Co. It was based on the design created by John Marlin in the late 1890s.


John Mahn Marlin began making lever-action rifles and carbines in 1881, and the fact that the company he founded is still making them is sufficient proof of the excellence. There have been some small changes, but since 1889 the significant feature of the Marlin has been the solid top to the receiver and the side ejection port.


The Marlin Model 375 gets its nomenclature from being chambered for the .375 Winchester cartridge, which was introduced specifically for use in lever-action rifles in order to give them a medium-to-high powered round for use in forests and close country. Note that it is a rifle rather than a carbine: the barrel is much longer than the magazine tube, and the whole weapon is three to four inches longer than the average carbine.

Marlin Action

The Marlin action retains the solid top receiver and has a cylindrical bolt which, on operating the lever, comes out from the rear of the receiver and has a cylindrical bolt which, on operating the lever, comes out from the rear of the receiver to cock the external hammer. At the same time, the cartridge lifter pivots to raise a fresh round from the magazine, and on the return stroke, the bolt chambers the round, is locked, and the rifle is ready to fire.

Sights and upper receiver

One advantage of the solid top and side ejection Marlin is that it makes life easier for fitting a telescope, and the receiver is factory drilled and tapped for a mount. Marlin has also added telescope shooters by making an extension hammer spur that protrudes to one side (either side, to choice) so that there is no danger of trapping the thumb between the hammer and telescope when cocking or lowering the hammer. Iron sights are fitted, a gold-bead foresight, and a step-adjustable rear sight with a rotatable insert that provides a choice of four notches.

The short magazine makes the rifle somewhat lighter at the muzzle than one normally expects with lever action, though this certainly helps when attempting to follow a moving target. Accuracy leans heavily upon the ammunition in use, but with the correct choice made, then groups between two and three inches are possible at 100 yards for the moderately practiced shooter.
