This review of the Stemple STG-M1A, presented by Ian McCollum of Forgotten Weapons, details its performance as a transferable machine gun. The firearm utilizes a Stemple 76/45 tube receiver in a Thompson-style casing and fires .45 ACP. While it mimics the Thompson's handling characteristics, including significant muzzle climb, its semi-auto function is non-operational, defaulting to full-auto. The analysis highlights its value as a more accessible alternative to an original Thompson submachine gun.
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.
