2020 Update: We've recently switched to NiB One™ plating (silver/gray color) on the lower assembly, magazine housing, and barrel jacket. This high performance finish adds greater durability and ease of cleaning compared to the black anodized finish.
U9 - Standard Bolt System
The STG Universal 9 (U9) features 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 rigid AK/ACE side-folding stocks or AR pattern stocks, AR pattern grips, and a variety of shroud and barrel options for both heavy and light setups.
Parts and Accessories Included With Each Gun: foregrip, 2 drums, 1 magazine, multi-tool, spare buffer, barrel locknut/muzzle cap tool, choice of barrel and shroud setup (sights not included)
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. Some of our customers who own the 9mm guns liken the full-auto performance to a laser beam.
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.
Capacity and Control
These guns use 70 round drums and are smooth cycling, heavy, accurate, and comfortable to hold. It's basically an assault rifle with a sub-caliber setup... a very controllable and accurate gun in full auto. 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. The 'laser beam' performance of this gun makes it one of the most enjoyable full auto guns you'll ever shoot.
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.

I purchased mine from BRP about 12 years ago. I had a minor issue with jamming the first month. BRP took care of that IMMEDIATELY. It has worked flawlessly ever since. I purchased it for investment and fun. Wow, has it paid back in both categories! It's worth many $1,000's more than what I paid for it. It is so much fun to shoot, and it never jams. Thanks Brian & BRP!

I've had one of these guns for about 18 months now. Fired about 10K through the gun with ONE malfunction from an improperly loaded stick mag. Flawless operation with the drums. Super easy to control and every one on the range wants to shoot it. I try to bring a little extra ammo for others to fire. This gun is so much fun I may buy another.
The guys at Gun Point said that they were really impressed with the quality of your workmanship on the Stemple. I told them that from what I've observed all of your parts are of impeccable quality.
I just received possession of my Stemple 76/45 STG Setup. The craftsmanship and quality of the build is impressive! The firing and handling was AWESOME! EXCEDED my expectations !
MY oldest nephew (45yrs), who also appreciates a quality product and a fellow firearm enthusiast, was also praising your product .
Great gun, love the way it breaks down comes with a case and all components. Like the fact that it shoots steel case cheap ammo. Brian is great to deal with and if you have any problems he takes care of it. Also it is a brand new gun just on a registered receiver. Great Value if you're buying machine gun. The only problem I see right now I have is I don't have enough money to buy more :-). David
