MP38 / MP40 Safety Ring (Collar Nut)

The MP38 / MP40 Safety Ring (Collar Nut) is the rotating collar positioned around the cocking handle slot of the receiver. By turning the collar into the safety position, the cocking handle can be locked in its notch, preventing unintended movement of the bolt during transport or handling.

Years of service, corrosion, or mechanical wear can damage the safety ring, making it difficult to rotate or preventing the safety from engaging correctly. Replacing the collar restores the proper operation of the original safety mechanism while preserving the authentic appearance of the firearm.

Manufactured from high-quality steel and machined to original dimensions, this MP38 / MP40 Safety Ring (Collar Nut) provides a precise fit and smooth operation. It is an excellent replacement component for restoration projects, collector-grade rebuilds, or replacing a worn or missing original part while maintaining the original mechanical design.
