Stemple Takedown Gun (STG) U9
U9 - Standard Bolt System
The STG Universal 9 (U9) 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 similar to the Suomi M31 which yields a cyclic rate of 750 rounds per minute. 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 a rigid AK/ACE side-folding stock, AR pattern grip, and a variety of shroud and barrel options for both heavy and light setups.
U9 Slow Fire (SF) - Heavy Bolt System
The Slow Fire (SF) utilizes an adjustable-weight bolt system to dissipate the energy in the recoiling mass during the cycle process. This is an ideal system for shooters looking to maximize suppressor performance by increasing dwell time in the chamber thereby reducing port noise. The cyclic rates with this system are adjustable between 525 to 900 round per minute. Shooters can customize their preferred rates simply by adjusting the bolt parts. At the lowest rate, this gun has a sustained fire of approximately 9 seconds with a 70-rd drum.
Simple / Durable Design:
Our guns are very difficult to break and very easy to fix. They are simple blow-back guns and very smooth-running in long full-auto bursts. Some of our customers who own the 9mm guns liken the full-auto performance to a laser beam.
There's nothing on these guns that cant be easily replaced. We designed this system to protect the registered receiver from any wear during use. The only parts that can wear can be easily replaced without the need to ship the gun back-and-forth.
If you need service, we are here to support our products.
