HK UMP Rear Stub and Hinge - Short
This listing is for a factory German HK UMP rear stub and hinge.
The rear stub does not include a rear sight assembly.
This part is for adding a folding stock in a USC-to-UMP conversion project, however, this particular stub was cut through the rear mounting hole, which is molded into the stub, and has been deemed to short for the job.
I would like to think it is not about the length of the stub, but how you use it, but, alas, we strive to provide as much information as we can... Sold as-is.
