If you go to Marlin's web site you can download a pdf file of the manual, which includes instructions on how to disassemble your 1894. http://www.marlinfirearms.com/pdfs/manuals/MFC_Centerfire_1894.pdf
The first step should be to read the owner's manual. You can request a paper copy from marlin, or go the the link below that says MARLIN, and it will take you to the owner's manual. Check that the rilfe is unloaded before performing ANY maintenance.

It is my understanding that a magazine from a Marlin 89C or 56 (both .22 rifles) or an Ithaca X-15 .22 rifle will fit the Seras 46DL. See your local gun dealer.
No. Yes they do: Marlin 917VS rifle
