Erquiaga EM-62: Castro's Ex-Armorer Makes an M14

This guide details the disassembly process for the gas trap variant of the M1 Garand, highlighting its differences from the later, more common models. It involves removing the bolt and operating rod first, then a specific screw to release the gas trap, followed by the sight block, before the gas trap assembly can be rotated off. This early design proved less reliable than the later gas piston system.
