Stemple Takedown Gun (STG) Stemple-Suomi

Product Description

Product Update Notes

2022: We introduced the new Internally Threaded Pattern (ITP) assemblies of the Stemple 76/45 receivers to offer a more streamlined and versatile system with enhanced compatibility among setups.  Per this previously approved method of attaching the trunion, separate trunions and bolt guides are no longer necessary for converting between the standard and heavy bolt systems. While these can still be used on the receiver, one trunion now does it all.  For example, the previous U9 conversion to the U9 slow fire setup required separate trunions/bolt guides, bolts, stocks, and buffers.  In the ITP setup only the stock and buffer assemblies are switched to add mass to the moving parts for lower cycle rates.  The bolt and trunion are unchanged.  The fire controls, stocks, and mag housings are also unchanged.  

The conversion from the U9SF to the U45 in the combination guns is also further simplified by having a much heavier 45 bolt so a second bolt extension is no longer necessary to reduce the cycle rate.

The STG1928 parts are also fully compatible with this setup.

Transferable

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.  

Parts and Accessories Included With Each Gun: 1 x 36rd magazine, 1 x 70rd drum, multi-tool, spare buffer, and 2 spare picatinny accessory rails for the shroud mount bipod and top optic mount.

Several Patterns Available:
1) Finnish Standard M31 Slant-Cut Shroud with removable bipod rail (12.75 in. barrel)

2) Finnish Compensated M31 Shroud with removable bipod rail (12.75 in. barrel)

3) Short Steel Shroud compatible with Atlas BT-15 rail mounts and used with 8.6" threaded or unthreaded barrels

4) Long BRP Steel Shroud Setup with Danish pattern flat front and quad rail capable.

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.

Easy-to-Replace Parts:
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.

Available Service:
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 9mm round 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.
