The original self-timing tuner muzzle brake.
Build the muzzle brake you need.
The highest blast reduction achieved in a muzzle brake, while being dissimilar in function to a silencer.
The coupler reduces blast to the shooter and your surroundings by regulating gas pressure to the atmosphere (while maintaining gas velocity) before it arrives at the muzzle brake, improving the shooting experience while keeping performance high, rather than containing, slowing down and cooling gasses to reduce pressure and velocity like a silencer would and ultimately hurting performance.
Threaded for Silencer-co Bravo on the front (any branded Silencer-co Bravo threaded muzzle brake is compatible) and threaded for Silencer-co HUB at the rear (any branded Silencer-co HUB threaded adapter is compatible). Build the coupler out, the way you want, with your favourite muzzle brake and mounting system.
Designed with the use of our high speed 50,000 HZ impact force sensor, MIL-STD 1474-D DB sensor and CFD flow simulations.
You’ll never go back to a regular muzzle brake after experiencing the reduced blast of the coupler.
(The coupler increases your base firearm’s DB level). (Pair with the Giga Chad End Cap for the ultimate in performance and blast reduction 6% more recoil but 60% less blast than the Chad. Be a CHAD, get a CHAD.)
Price range: $225.00 through $375.00

Product FAQ
What is the COUPLER?
The Coupler is a CNC Machined Stainless Steel (300 Series Stainless) controlled venting coupling. Because the coupler vents to the atmosphere, it not only reduces blast to the shooter, but also to the surrounding area by releasing pressure to the atmosphere before it reaches the muzzle brake. The coupler is not a silencer because it doesn’t capture gas or suppress the muzzle blast, it instead releases it, dampening the increased effects muzzle brakes have on muzzle blast and overpressure. The coupler is threaded for Silencer-co Bravo on the front (any branded Silencer-co Bravo threaded muzzle brake is compatible) and the rear is threaded for Silencer-co HUB (any branded Silencer-co HUB threaded adapter is compatible). This allows you to build the muzzle brake that you want, with a reduced blast experience without sacrificing performance in order to achieve it.
Why is it called the COUPLER?
We called it ‘the coupler’ because that’s exactly what it is. A double female threaded tube ie coupling; that joins two components. The coupler allows you to build it out with any branded Silencer-co Bravo and HUB-compatible products, not just ours. So customers can build the muzzle brake they want and need based on their preferences.
It is the ultimate reduced concussion muzzle brake for modern precision rifles; lightweight and NRL hunter style rifles or heavy PRS style competition rifles.
How do I clean the COUPLER?
Same way you clean the Giga Chad End Cap high performance aluminum muzzle brake. Using an ultra sonic cleaner filled with Simple Green or equivalent industrial detergent. Run 2-3 cycles on the highest temperature setting and it’ll come out looking literally brand new (do not soak in CLR or Lemi-shine, the Silicone mirage shield will be destroyed). (Be careful with high temps and cleaning agents, the evaporated gasses are very toxic).
What is Diamond-like Carbon?
Diamond-like Carbon is a type of amorphous carbon material that displays some of the typical properties of diamond and can be applied via physical vapor deposition to substrates including metals, ceramics, glass, and polymers.
What is Physical Vapor Deposition?
Physical vapor deposition is characterized by a process in which a solid is transitioned from a condensed phase to a vapor phase and then back again to a thin film condensed phase within a vacuum. The coating left behind by the process is five to ten thousands of an inch thick, many times harder than any heat-treated steel and has the additional properties of a dry lubricant.
So, parts hold dimensional accuracy, while improving wear resistance, lowering the coefficient of friction, improving corrosion resistance and improving lubricity, while the coating remains inert to chemicals. Which is one of the main reasons why we use DLC and PVD coatings on our products.
Although DLC and PVD coatings are applied the same way, DLC and all the various versions of PVD applied materials, are all very different chemically (despite all achieving the same thing), which results in them all being wildly different coloured in their final condensed phase. For example; Titanium nitride being gold and Diamond-like Carbon being black, yet still having very similar properties.
This is how we’re able to offer different finishes like gold and rainbow, that are inert (un-affected by cleaning agents) and more durable than the hardest heat-treated steel’s finishes.
General FAQ
What warranty do you offer?
All products come with a no-nonsense lifetime warranty.
If you notice something isn’t quite right when you receive your product or something strange happens to it, contact us so we can exchange or repair it, whatever is quicker. (We will always request the original item is returned to us for inspection). (Warranty does not include coatings).

We no longer offer refunds for change of mind.
Please be aware of lead times, product finishes and necessary accessories before making purchases. Our Terms and Conditions page outlines our policies. Email or call for clarification if needed.
Do you have any dealers or only sell direct to the public?
We are in the process of setting up more dealers in the USA and around the world. If you are interested in becoming a dealer, please contact us to discuss terms. Our current USA dealers and International distributors are linked below.
(If we are out of stock, our dealer network is the best place to find stock. If you’re having trouble finding stock at our dealers, contact us, we are always aware of how much stock dealers have).

Are you in the military or have you been associated in the military in any way?
No. We are not ex-military and have not/do not claim to have/had any association with the military but we appreciate the sacrifice the boys have made past and present and is one of the reasons why we offer a military discount to thank all military members for their service. We are a small company but offer what we can.
What’s the companies name? I’m confused.
The company’s name is Without Warning.
Our old URL was strikewithoutwarning and that caused some confusion amongst customers. That was simply the URL because withoutwarning was taken. Nothing more, nothing less.
What targets are used in your YouTube videos?
The targets used in the tuner series of videos are simply a .pdf file printed at the local printer shop onto a3 cardboard, download them below. The target is a 0.1 mil grid with 0.1 mil orange squares. They are rotated 45 degrees, so you have fine aiming points for shooting groups. We find this is much more consistent than shooting at circles etc.
