I couldn't find any reference to it in this years Blue Book. It is marked Mod. 336Y
The LOP is 12.5" and the barrel measures 16.75" to the face of the bolt. Plus, it has the rubber butt pad. It tips the scales at 6.5# with the sling. Using Marlin's method of serializing makes this one a 2003 year of mfg. Any info is appreciated.
