USMC AK-47 Armorer’s and Organizational Maintenance Guide: TM 8370-50007-IN/2, NSN: 1005-LL-MUS-2940, Organizational Maintenance Instructions

This Milstar Books Military Doctrine Collection reprint presents the official United States Marine Corps Organizational Maintenance Manual for the 7.62mm AK 47 rifle. Originally issued by Marine Corps Systems Command in December 2009 as TM 8370 50007 IN/2, this technical manual delivers detailed, step by step maintenance procedures, inspection standards, and repair parts guidance for armorers, unit maintainers, and advanced students of the Kalashnikov system.

Written in the structured Marine Corps work package format, the manual covers service upon receipt, preventive maintenance checks and services, general maintenance, disassembly and reassembly, function checks, gaging procedures, storage and shipment preparation, and final inspection and testing. It also includes a comprehensive troubleshooting section, safety and handling guidance, auxiliary equipment information, special tools lists, expendable and durable items lists, and a full repair parts list. Clear illustrations, callouts, and standardized procedures make this a practical bench reference rather than a casual overview.

This Milstar Books edition preserves the complete original text, diagrams, and technical data while adding standardized formatting, a new cover, and modern front matter for clarity and durability. Whether you are a military historian, collector, firearms technician, or serious student of small arms maintenance, this volume provides an authoritative, primary source reference on how the U.S. Marine Corps maintained the AK 47 at the organizational level.
