Nylon Thread Protector for the new Universal Stemple 76/45 threaded Trunion pattern.
The front of the Stemple 76/45 Receiver is internally threaded for the installation of the new Universal pattern threaded trunion used
for the U9, U9SF, U45, 34k, Stemple Suomi,
& U9 setups. This trunion is not used with the STG1928 pattern parts for the Stemple 76/45. To protect the threads while the STG 1928 parts are in use, roll and insert this Nylon strip into the front of the Receiver prior to installing the Bolt Guide Assembly. This Nylon strip serves
to protect the threads and isolate movement of the STG 1928 Bolt Guide Assembly within the Stemple 76/45 Receiver.
