This gun is ideal for a suppressor. The extra bolt weigh drastically slows the initial bolt blow-back thereby significantly reducing port noise common in open-bolt / blow-back SMGs.

The STG Universal 45 (U45) is our newest addition to the U Series setups for the Stemple 76/45 machine gun. They feature a simple, smooth-running blow-back system. With the addition of a hydraulic buffer, these are the most smooth, controllable, and versatile subguns on the transferable market. It's so smooth due to the weight, layout, and action; you can actually watch your target being hit through a 4x scope while shooting long bursts. This setup utilizes AR pattern stocks, AR pattern grips, and multiple picatinny mount options for maximum versatility. Shooters can customize their preferred rates simply by adjusting the bolt parts.
The U45 setup uses the same U Lower Assembly, Barrel Shroud, and Adjustable-Weight Bolt System as the U9 SF. If you already own a U9 SF, the U45 conversion kit consists of the bolt, barrel, and mag housing.
The setup tested in the above video uses a CAR stock with hydraulic buffer and has a combined bolt resistance weight of 1.91 pounds. With the longer A2 stock, we can use the heavier bolt extension to further reduce the cyclic rate.
