Marlin 336/444 Skull Magazine Tube Plug (sphere)

Magazine tube plug for TIP-CAP style Marlin 336 and 444 rifles, with skull on half-sphere. Will not work for most barrel-band style rifles. Polished Bronze Steel is the recommended material, and the material the part was designed around. May require some fitting. I have done my best to adjust the dimensions to compensate for the shrinkage rate of the Bronze Steel and other stainless-based materials, but the "up to 30% shrinkage" rate of the material means that I erred on the side of being over-sized, so that minor fitting can correct a dimensional issue; whereas being too small would just be a bad part.
