Smashing Steel

Thureon Defense
Smashing some steel from Gun Fighter Targets with the Thureon Defense 9mm carbine.

Few people have the skill set of Mr. Rob Tate! He and Ric took the Thureon Defense “Competition Model” to the range last Sunday and ran about 500 rounds through it.
ZERO failures!
1″ groups at 100 yards!

Configured with a low profile upper receiver and 15″ hand-guard, this is off-the-shelf-ready-to-win!

Thureon Business Update

Good afternoon,

Here is my suggestion for the notice on Facebook.  Make any changes you like.  Return it to me and I will post it ASAP. If you want a picture added, attach it to the returned email.


After much consideration, we have decided to sell Thureon Defense to someone who can take it to the next level and grow the company to its full potential.  The new owner has successfully managed (and grown) a couple of businesses, and we feel confident he will do the same for Thureon Defense.


The new company — based in Wisconsin just north of Milwaukee — will retain the brand name, commitment to a quality product, and dedication to superior customer service.

Another point of consistency is that the new owner, Ric Czarnecki (pronounced ZAR-nek-kee], has a difficult-looking last name!!!  Ric owns Clearshot Manufacturing, a machine shop that primarily makes very precise screw machine parts.  Clearshot has been a vendor of Thureon Defense, supplying firing pins, charging knobs, and other small parts.


I will be helping with the transition and training, and retained as a technical resource.  I have some ideas for new products to improve the versatility of the Thureon Defense carbines, and will be excited to see imagination become reality.


I want to express my thanks and gratitude to the companies and individuals who have supported us throughout the years.  Your suggestions and kind words of encouragement are greatly appreciated.


We remain – “Thureon Defense.  The Shield of Liberty!”


What kind of ammunition you should use

Thureon Defense

The 9mm Thureon Defense firearms are chambered for the 9 x 19mm cartridge, and are designed to function with a wide spectrum of 9mm ammunition. We have tested our carbines with ammunition ranging from subsonic velocities to +P power levels. All of them cycle the action consistently and function reliably. Any variant of the 9 x 19mm cartridge is acceptable, whether labeled “Parabellum”, “Para”, “Luger”, or “NATO”.
The only exception is the CCI Blazer, aluminum cased, ammunition. Thureon Defense has nothing negative to say about the CCI brand or their Blazer line of products; it simply doesn’t work well in our firearms. While Blazer ammunition is safe to shoot in the carbine, you may experience feeding problems when using it.
Of course, .380 ACP, 9mm Browning, and 9 x 21mm ammunition should never be used in these firearms. It is the shooter’s responsibility to make sure the ammunition exactly matches the specifications for their firearm.
Safe gun handling requires that you always check your ammunition to be sure that it is in good condition. Discard any cartridges with visual signs of corrosion or damage.
The use of improperly reloaded ammunition can also be dangerous. Firearms are designed, manufactured, and tested to published industry standards. Hand-loaded or reloaded ammunition that deviates, either intentionally or accidentally, from specified loadings can be extremely hazardous. It is strongly recommended, therefore, that you use only factory ammunition from a reputable ammunition manufacturer. If you do reload, you have assumed the risks and responsibilities of an ammunition manufacturer.
