Stemple 76/45 + Russian Lend-Lease Thompson Kit = STG-M1A
This guide details the disassembly and reassembly of the Stemple STG-M1A, a unique submachine gun built using Stemple tube receivers and Russian lend-lease Thompson parts. Expert Ian McCollum demonstrates how the 'round peg in a square hole' design allows for the use of original Thompson furniture while maintaining the legal status of the Stemple receiver. The process involves removing the receiver tube from its housing and extracting the bolt and recoil spring assembly for cleaning and inspection.
