Marlin Parts

Marlin has been building rifles since the 1880s, and Jack First stocks replacement and obsolete parts across more than 70 of its model families.
Rifles — 60 model families spanning the lever-actions and the .22 rimfires Marlin sold in enormous numbers: the 336 in both early and later production, the 1894 in its many chamberings, the 39, 39A and 39M lever .22s tracing back to the 1897, the 444 and 444S, the 99, 99C and 99M1 semi-autos, the 990 and 995, the 80 and 81 bolt rifles, the 49 and 49DL, the 781 and 782, and the 882 and 883 .22 Magnums.
Shotguns — 10 families including the 120 and 778 pump guns, the 43, 44, 53 and 63 pumps, the 50, 55 and 55G bolt-actions, and the early hammer guns of the 1898-1921 era.
Marlin frequently revised these models across long production runs, so parts commonly differ between early and late examples carrying the same number — the 336 and 1894 are each split into separate production groups for that reason. Matching the part to the production period matters as much as matching the model. For Marlins of the 1890s and early 1900s, see also our antique gun parts.
