Before you use your suppressor, we strongly recommend that you review the guide and always use the four basic rules of firearm safety.
*Treat every firearm as if it is loaded.
*Always keep the muzzle pointed in a safe direction.
*Keep your fingers off the trigger until you are ready to fire.
*Know your target and what is behind it.
Suppressors work similarly to an automobile muffler.  In consideration of this, remember that they can greatly reduce the sound signature of most gunfire, but not completely eliminate it.  Some of our suppressors do get close to “Hollywood quiet”, but nothing is ever as quiet as the movies would lead you to believe.  In addition, there are many things that can affect the performance of the suppressor.  Such as ambient temperature, humidity, elevations, weapon condition, suppressor condition, ammunition type, etc.  All of these things together or individually can make your suppressor perform a bit better or worse.
USE:  We manufacture two types of suppression systems.  Attachable (screw-on) and Internal Systems.  Internal suppressors are “ready to go.”  Please adhere to the specific ammunition advice you were given for our internal system.  For example, we DO NOT use sub-sonic ammunition for .22 long rifle internal suppression systems; standard velocity ammunition is perfect.  We do recommend that you use sub-sonic ammunition in the .308 internal suppression system.  Our internal suppression systems are designed to be “shot dry.” 
Muzzle mount suppressors must be attached to the muzzle of your weapon.  Make certain that your weapon is clear before you attach or remove a suppressor!  Carefully align the threads and rotate the suppressor until it is completely engaging the thread and is hand tight. 
It is recommended that you do not allow the suppressor to remain in an overheated condition for a prolonged period of time.  
CLEANING:  There are no user serviceable parts in our muzzle mount suppressors.  That means there is not a lot you can do to it.  Try to blow out the debris after use with compressed air.  (The small cans you use on a computer work great!)  You may also soak the entire unit in non-ammonia-based solvent or utilize an ultrasonic cleaning system.  Please bear in mind that prolonged use of an ultrasonic cleaner on a suppressor with a damaged finish can accelerate the wear of the finish.  This will not harm the function but may detract from the finish.  Allow the suppressor to dry completely.  Store in a clean, dry environment. 
Integral suppression systems allow the user to do a little more cleaning.  The end cap will twist off with the supplied pin wrench.  Once the end cap is off, you can remove the baffles one by one with a small hook or similar device.  Make careful note of the order in which the parts came out!  You should not attempt to remove the barrel nut or the outer tube of the system.   Clean each baffle with a bronze brush and non-ammonia-based solvent.  Allow to completely dry.  You may clean the rest of the firearm with the same type of solvent used in a standard cleaning method.  A bronze brush is recommended for removing “crud” from the barrel and the area between the barrel and the outer tube.  Reassemble in reverse order and align the “ports or dimples” in the baffles as the go back in.  Try to aim for the 12 o’clock position of the ports in each baffle.  Screw on the end cap with the pin wrench to just passed hand tight.  Do not expect your cleaning to result in a “factory new” state as this is nearly impossible to achieve.

User Care and Cleaning

"Dark Horse makes the quietest, best shooting suppressors and suppressed guns I've ever shot. Their service is exceptional, and I wholeheartedly recommend them." -- Kolton W.

"I have purchased a number of suppressed weapons from Dark Horse over the past eight years.  Dark Horse provided excellent support before and after the sale.  Great Products.  I have killed numerous hogs with my suppressed .308 rifle." -- Craig N.


Our products work. If they don’t, we fix them. We know that sometimes specific applications will require some “tweaking.” We’ll tweak. If the suppressor breaks because of something we did, we’ll fix it. If the suppressor breaks because of something you did, we’ll probably complain a bit, but we’ll still fix it if we can. If there’s a problem, call us.

Recommended cleaning

Suppressors get dirty. You’ll want to blow out the dirt and crud as soon as possible after shooting. Some “cans” can be taken apart and some cannot. We recommend that you use a non-ammonia based cleaning solvent to rinse the interior. A brush will help on parts you can get to, but you shouldn’t worry about what you can’t reach.
