The STG Universal 45 (U45) is our newest addition to the U Series setups for the Stemple 76/45 machine gun. It features 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.
This gun is also ideal for use with 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 U45 setup uses the same U Lower Assembly, Barrel Shroud, and Heavy 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.
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. There is only a limited number of these pre-1986 registered/transferable machine guns remaining, so get one while they last.
If you are going to buy a transferable machine gun for some serious shooting, you should consider the Stemple Takedown Guns for these reasons:
They are ‘new’
Well, the receivers are nearly 30 years old but the Stemple Takedown Gun (STG) setups are complete new parts packages installed on unused pre-1986 transferable Stemple 76/45 machine gun receivers.
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.
By using Picatinny rails (MIL-STD-1913) for sights and hand guards, shooters can add a variety of accessories and optics. The configurations with the Adjustable Bolt System use common AR pattern stocks and grips with hundreds of options currently available.
There’s nothing on these guns that can’t 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.
Shoot Cheap Ammo
We typically just shoot steel-cased ammo. Our milled steel trunions easily deal with potential wear issues from any type of ammo.
Can't Get Too Hot
These are ideal for machine-gun shoots. The low-pressure pistol ammo cannot create enough heat in the barrel to cause a malfunction or damage the gun. There's no gas system to clog, and the open-bolt system negates any cook-off risk.
