Is there anyone out there who know how to disassemble a Remington Fieldmaster 121 tube load 22 pump rifle. Something tells me I am not doing my post correctly.
You can purchase a takedown schematic for your Remington Model 121 from Numrich Gun Parts Corporation: 845.679.4867 (Customer Service). Check their Website at: www.e-gunparts.com/model.asp?idDept=204
This link should take you directly to their listing of schematics available for various Remington models, then simply scroll down the list to 121. They show that a new on-line-viewable (free) version is available, and this may provide enough information to answer your questions. If not, then simply purchase the fully-detailed version.
The Remington Model 121 Fieldmaster was introduced in 1936 and continued in production until 1954. It was offered in six grades: 121A (Standard), 121D (Peerless), 121E (Expert), 121F (Premier), 121ES, and 121FS.
