Thorpe EM-1: A Bullpup Take on the Roller Locked Gerat 06

Published on July 6, 2017
Duration: 21:08

This guide details the complex field stripping process for the experimental Thorpe EM-1 bullpup rifle, developed in post-WWII Britain. It highlights the unique steps required, such as stepping on the butt plate to remove the action, and emphasizes the rifle's intricate roller-locking mechanism derived from the German Mauser Gerät 06. The information is presented with high authority by Ian McCollum, an expert in rare firearms.

Quick Summary

The Thorpe EM-1 is an early British bullpup rifle design from 1947-1950, based on the German Mauser Gerät 06. It features a complex gas-operated, roller-locked action chambered in .280 British, with a 1x optical sight. Its intricate mechanism, including a long-stroke gas piston, made it overly complex compared to the simpler Gerät 06.

Frequently Asked Questions

What is the Thorpe EM-1 and what is its historical significance?

The Thorpe EM-1, developed between 1947-1950, is one of the earliest British bullpup rifle designs. It's heavily based on the German Mauser Gerät 06, utilizing a gas-operated, roller-locked mechanism and chambered in .280 British, reflecting post-WWII British small arms doctrine.

How does the Thorpe EM-1's roller-locking system differ from the Mauser Gerät 06?

While both use roller-locking, the Thorpe EM-1 employs a more complex long-stroke gas piston system. In contrast, the Mauser Gerät 06 utilizes a simpler short-stroke gas piston system, making the EM-1's mechanism significantly more intricate.

What are the key external features of the Thorpe EM-1?

The Thorpe EM-1 features a bullpup configuration, a 1x optical sight with hold-over lines, an AK-style magazine release, and a built-in stripper clip guide on its 20-round magazine. It also has a walnut veneer on the rear receiver for insulation.

Why was the Thorpe EM-1 ultimately rejected?

The Thorpe EM-1's complexity, particularly its intricate roller-locking and gas piston system, contributed to its rejection. It was eventually superseded by the Janson EM-2 design, which offered a more practical and less complicated solution.
