Frequently Asked Questions

What tools are essential for cleaning a Marlin 39A rifle?

Essential tools include a high-quality, plastic-coated spring steel cleaning rod, cotton flannel patches, soft padding, a hardwood wedge, a bore light, a 3/32 drift pin, and a bladed screwdriver. A U.S. quarter is recommended for the takedown screw to avoid damaging the finish.

What type of brush should be used for cleaning the Marlin 39A's bore?

A bronze bristle brush is mandatory for cleaning the bore of the Marlin 39A. Steel brushes should be strictly avoided as they can damage the relatively soft steel of .22 caliber barrels.

What solvent and lubricant are recommended for the Marlin 39A?

Hoppe's No. 9 is the preferred solvent. For lubrication, simple mineral oil is recommended over complex proprietary oils. Grease should be applied sparingly to specific high-friction points in the action.

How do you perform the takedown procedure on a Marlin 39A?

Use a quarter to loosen the takedown screw. Then, a light strike on the side of the barrel (avoiding the magazine tube) will separate the receiver halves, allowing access to the internal mechanism and bore.
