The FG-42 (Second Model) was a German paratrooper rifle designed to meet stringent Luftwaffe requirements, including matching the Kar98k's length and weight while offering both semi-automatic and full-automatic fire. Its innovative design features a rotating bolt, a dual-mode firing system (open bolt for full-auto, closed for semi-auto), and a spring-loaded stock to manage the recoil of the 8mm Mauser cartridge. Disassembly reveals a complex but logical mechanism, including a unique side-mounted magazine and a bolt/gas piston assembly.

Quick Summary

The FG-42 (Second Model) was a German WW2 paratrooper rifle designed to match the Kar98k's size and weight, offering both semi-auto (closed bolt) and full-auto (open bolt) fire in 8mm Mauser. Its innovative spring-loaded stock significantly reduced recoil.

Frequently Asked Questions

What were the key design requirements for the German FG-42 paratrooper rifle?

The Luftwaffe required the FG-42 to match the Kar98k's length and weight, be magazine-fed, chambered in 8mm Mauser, and feature both open-bolt operation for full-auto fire (preventing cook-offs) and closed-bolt operation for semi-automatic accuracy.

How did the FG-42 manage recoil from the 8mm Mauser cartridge?

The FG-42 incorporated a unique spring-loaded stock where the entire action could compress into the buttstock under recoil. This, combined with multiple recoil springs, significantly reduced the felt kick, making the rifle manageable.

What distinguishes the second model FG-42 from the first?

The second model FG-42 is primarily identified by a less steep pistol grip angle and a receiver constructed from stamped metal rather than milled parts, contributing to easier manufacturing and a lighter overall weight.

Can the FG-42 fire from both an open and closed bolt?

Yes, the FG-42 features a dual-mode firing system. It fires from an open bolt in full-automatic mode for better cooling and from a closed bolt in semi-automatic mode to enhance shot accuracy and reliability.
