Product Details
Demilled MG3 grip mounting base on receiver stub. The receiver section is crushed but is good for spare spare material and measurements. The grip mounting base can be removed and reused, some may need straightening.
Rhinemetall demilled these receivers by removing small parts and driving over the receivers with a tank (true story). That is how they were crushed.
This is a hard to find part and cane be very helpful for many Yugo M53 or German MG42 builds.
