How do you disassemble a 375 Marlin rifle?
Open the lever halfway. Remove the lever screw, and drop the
lever out. Grasp the rear of the bolt, and pull it out the back. Be
sure to have the gun on it's left side, so the ejector wont fall
out. Then reach inside the ejection port, and lift the ejector out
of it's notch. This is as far as you need to take it down for
normal cleaning. Spray the internals out, and scrub the bore.
