This Stemple 76/45 setup is part of "Universal" series and is fully compatible with the other setups and packages in the product line (e.g. U45, U9, U9SF, 34k, U7.62, & STG76 setups).


In 2003, the original inventor, John Stemple collaborated with BRP Corp to make new and replacement parts for the Stemple 76/45 receivers he manufactured prior to the 1986 cutoff.  From this came a series of compatible drop-on parts for the unmodified/transferable Stemple 76/45 receivers known as Stemple Takedown Gun (STG) setups.  Since nothing is welded or hand fitted to these receivers, changing setups and replacing parts is fast and easy.  These are the most finely built and smooth running sub-machine guns on the transferable market.  We build them for performance and durability, stock plenty of high-quality spare parts, and provide excellent service.  



STG-76W (Stemple Suomi 9mm): The Stemple Suomi closely resembles the original Finnish KP31 by using the original Finnish KP31 wood stocks, sights, and shrouds.  The KP31 had some of the nicest 'furniture' ever put on a a sub machine gun.  It can be equipped with short M37 barrel/shroud, M31 barrel/shroud, or suppressed setup.  Bipods are available for all patterns.  To accommodate the sear location of the Stemple receiver, we designed as new trigger system based on the MP40.  Similarly, this configuration is full-auto-only. 




Parts and Accessories Included With This Gun: 1 x 36 rd magazine, 2 x 70 rd drums, bipod, multi-tool, sling, spare buffer, wooden transit chest (pictured below), and 2 spare picatinny accessory rails for the shroud mount bipod and top optic mount.
