The Marlin Model 336 appears as the “Lockwood Mk2”, under the marksman rifles class. It is depicted as being chambered in the .45-70 Government cartridge, like the Marlin Model 1895 that previously appeared in Modern Warfare as the “MK2 Carbine”, but this time the shape of the ejection port indicates that it is a Model 336. It features the same basic ammo options as the other marksman rifles; notably, this includes armor-piercing ammo – while .45-70 AP rounds do exist (e.g. Lehigh Defense’s X-Treme Penetrator rounds), the ones in-game are visually the same as the other calibers (likely for consistency’s sake), with a black-finished case, a silver jacket, and a black spitzer-type point. Realistically, loading spitzer-pointed rounds in a tube magazine could lead to a chain-detonation (i.e. one round’s point impacting the next round’s primer), blowing the entire magazine tube apart.
