The original self-timing tuner muzzle brake.

As competitors that actually spend time on the podium, we know seeing impacts is everything, so we’re here to fill gaps in the market previously overlooked by manufacturers and pave the way for positive new trends in the industry to address the lack of focus put on rifle balance, weight distribution, muzzle rise and recoil management to get you seeing as many impacts as possible and thus improving your scores. 

Chosen by the worlds best.

More performance, less concussion.

chad – tuner muzzle brake (morgun king edition)

The tmb (tuner muzzle brake) disrupted the muzzle brake industry in 2020 and together, we made muzzle brakes cool again, but now, the new patent pending CHAD tuner muzzle brake with its novel design, and it’s insane performance, changes the industry forever with it’s re-directed blast design that results in no muzzle rise and a blast free shooting expereince.

The CHAD is a six-piece stainless steel muzzle brake that’s CNC laser welded together into a single assembly. Each piece has a tapered interface, that aligns the assembly’s pieces perfectly giving us industry leading levels of run out. Due to its multiple piece design we’re able to create geometry, easily, that’s otherwise impossible via conventional means. This means performance not previously seen before while maintaining shooter comfort. Designed with the use of our high speed 50khz impact sensor and SolidWorks flow simulations, we were able to design and refine the CHAD in ways the competition aren’t even aware of.

It still features an integrated 24-position, adjustable and locking harmonic barrel tuner (a without warning exclusive and first), however it now lives inside the muzzle brakes body protecting it from impacts, and due to its location, no longer hangs over the barrel, meaning you no longer need to cut your barrel to make it fit, if you run a straight barrel like we do here at without warning; everything is forward of the shoulder.

We led the industry in recoil reduction with the tmb (tuner muzzle brake) and the improvements we’ve made with muzzle rise reduction and blast redirection, takes what we already had and catapults it to another level.

In our latest testing we bested all the market’s current brakes, while redirecting the blast up and away from the shooter to create a blast free shooting experience with no muzzle rise.

Don’t be a liberal cuck that doesn’t know what bathroom to use, be a CHAD.

Product FAQ

What is the CHAD?

The patent pending CHAD is the original six-piece stainless steel muzzle brake, CNC laser welded together into a single assembly. It’s a 47.5-degree rearward and 15-degree upward, 5-port self-timing, directional muzzle brake with an integrated and internal 24-position, adjustable, and locking harmonic barrel tuner, that simply threads onto your muzzle, as one assembly, like every other normal self-timing muzzle brake on the market currently (just like the tmb, the original tuner muzzle brake developed by without warning).

Why did you discontinue the tmb (tuner muzzle brake) and come out the with CHAD?

Unfortunately, the tmb (tuner muzzle brake) was copied more times than we can count. It was the original self-timing tuner muzzle brake back in 2020 and created the tuner muzzle brake segment. We knew this would happen and always intended on releasing a newer and better product to counter this trend once the market began to become saturated with clones of our original design.

The patent pending CHAD is better than the tmb (tuner muzzle brake) in every way, and we will aggressively defend this IP, while our lame competitors fight over our crumbs with their poor clones of our original design.

What’s difference between the tmb (tuner muzzle brake) and the CHAD?

Everything is different.

It’s not an evolution but a complete redesign from the ground up.

The biggest difference being the CHAD isn’t a shell with inserts like the tmb. It’s six individually machined pieces laser welded into a single assembly, (like tubeless silencers). This allows us to create more complex internal geometry than the tmb which results in higher performance and higher durability for larger calibers, compared to the tmb and its caliber limitations. The geometry is similar but is improved; an example of how it’s changed is now, were able to maintain critical geometry that was important to the tmbs design, while at the same time, angling the already upwards biased side ports forward and upwards at a 15deg angle, resulting in more muzzle rise control without sacrificing recoil reduction performance. Something no other brake is capable of simply because of how they’re machined.

We will release videos detailing our recoil reduction technology once patents are finalized.

Another interesting difference is the tuner is now inside the muzzle brake body. This eliminates the extra width the tmb’s tuner created and people complained about. It also protects the tuner from impacts and eliminates the tuner overhanging the barrel which people also complained about. The entire muzzle brake is now forward of the shoulder.

Why is it called the CHAD?

CHAD is a “slang term that refers to a stereotypical alpha male; he is depicted as attractive, successful, muscular, cocky, and very popular among women (or otherwise a genetically superior male).”

It’s intended as an insult to the competition and their inferior beta products (that are all just copies of each other and recycled old technology), but is also a reference to the chad’s performance and it’s place in the hierarchy of things.

It is the ultimate tuner muzzle brake for modern precision rifles, long range hunting rifles and PRS style competition guns.

Will the CHAD fit my rifle and how do I install it?

The CHAD simply threads onto any 5/8×24 UNEF 2A/3A threaded muzzle like any other self-timing directional muzzle brake. (Minimum shoulder diameter the CHADs jam nut will work with is .81 inches. The CHAD is made for thick contour barrels used on modern precision rifles, PRS style competition rifles and carbon barrels, not sporter hunting rifle barrels. The thinnest barrel the CHAD will work on is a medium palma).

Thread it onto the muzzle clockwise until it stops. Then thread it anti clockwise until the side ports line up horizontally (the CHADs ports are closer together on the top than the bottom, make sure it’s installed properly, or it’ll increase muzzle rise). Then rotate the jam nut clockwise until it contacts the shoulder and torque it against the shoulder to 25 FT LBS. If your CHAD becomes carbon locked onto the barrel the easiest way to remove it is to get a rubber mallet and tap a crescent wrench or spanner in a clockwise direction to break the carbon and loosen the device.

The tmb (tuner muzzle brake) came with a tool, do I need a tool to install the CHAD?

No, you don’t need a tool for the CHAD.

The reason the tmb needed a tool was, the spline drive interface for tightening the jam nut, doubled as markings for the tuner and the tool was the solution to combining the two. Due to the tuner being inside the CHAD and being on the other end of the brake there’s no longer a need for a proprietary tool. Use a normal crescent wrench, spanner etc to torque the CHAD onto your barrel (recommended torque 25 FT LBS).

What is a barrel tuner?

A harmonic barrel tuner is a device that manipulates the harmonic frequency that your rifle barrel vibrates at when firing ammunition.

A compact and correctly sized weight (usually around 4oz) is located at the muzzle and when moved in increments of 0.001 of an inch (forward or backwards), manipulates the harmonics of your rifle barrel to correctly line up the upward swing of your rifle barrel’s vibrations with the exact moment your bullet leaves the end of your barrel, resulting in more consistent and precise group sizes despite the speed the bullets are travelling at. Usually resulting in around 50% smaller group sizes.

This can be done by shooting groups and making adjustments on the tuner to find the correct setting for your load and barrel combination. Trial and error.

A harmonic barrel tuner is the only device that can externally change a rifles performance and the barrel to ammunition relationship, without making changes to your ammunition.

How do I use the tuner on the CHAD?

Check out our video series on the CHAD on our YouTube. We go into how to tune factory ammo, handholds not meant for your rifle, and how to approach/cover load development using a tuner. We cover many methods, show all results, and are happy to complete new videos or answer any questions you might have.

To adjust the tuner, unscrew the tuners set screw with the provided hex tool (5/64 hex tool) anti-clockwise 1-2 turns, then turn the tuner anti clockwise one adjustment, line the notch on the tuner up with the next notch on the muzzle brakes body (anti-clockwise) and then tighten the set screw until it stops, then torque to 18 IN LBS.

We also have a detailed guide here on the website on how to use a tuner, it details different methods and approaches to using a tuner with load development.

What’s a better location for the tuner, at the muzzle or at the front of the muzzle brake?

Both have pros and cons.

We believe a larger weight at the muzzle like the tmb (tuner muzzle brake), rather than a smaller weight at the end of the brake, is the better way to design a tuner muzzle brake but it has drawbacks like; it’s significantly increased diameter, which can hang up on things when moving the muzzle in, out and around obstacles during competition, it’s exposed, and needs to be very durable to handle impacts without it shifting, the tuner overhanging the barrel, causes barrel profile fitment issues and some people complain it has a ‘unique look’.

But as long as both are designed well and have a generous amount of adjustment to reach different peaks in the vibrations of your rifles barrel then you should have the same success as you would with a tuner muzzle brake design like the original tmb (tuner muzzle brake).

How do I clean the CHAD?

Same way you would clean any other high performance muzzle brake. Soak it in a quality carbon cleaner for up to 1-2 hours (CLR is best) and scrub the excess carbon off the outside with a dishwashing chux, every 300-500 rounds when you perform your barrels regular cleaning cycles. Don’t worry about scratching it with a chux, the DLC finish is harder than what you’ll be scrubbing it with. CLR or similar cleaners will not damage the CHADs DLC finish if you stick to the above guidelines. (Make sure you remove the tuner and jam nut first before soaking in CLR or harsh chemicals that will damage and eat away at aluminum and brass. We will not warranty this.)

For example, after soaking the CHADs brake (do not soak the jam nut or brass tuner) for up to 1-2 hours in CLR to soften/remove all carbon from the brake, rinse it in warm soapy water and scrub the outside clean with any typical green dish washing chux. The water pressure going into the ports should be enough to remove all soft carbon residue left behind. If repeated cycles are necessary, soak again. Don’t use tools to scratch and compromise the integrity of the coating. Doing so will allow CLR to penetrate between the coating and the substrate and destroy/remove the coating.

Why does the CHAD use 3A threads instead of the industry standard 2A?

The current industry standard for suppressors/silencers is 3A/3B because class 3 threads basically have a tighter and more precise fit. We use this same class of thread because 2A/2B and 3A/3B mating parts are designed to be interchangeable and fit together to allow free-running assembly with no interference. Thread fits are developed using allowances and tolerances. Class 2 threads have allowance and tolerance, whereas class 3 threads only have tolerance.

Provided your threads are cut correctly and not specifically matched to a specific muzzle brake by an ignorant gunsmith, there is no downside to using a class 3 threaded device on a class 2 threaded barrel. It’s a more precise fit and since we are running custom barrels on precision rifles, it makes sense to use more precise threads. Next time you get a barrel spun up, ask your smith for class 3 threads, your muzzle brake will install more concentric to the bore.

How long should my muzzle threads be?

The CHAD was made to work with muzzle threads .625 inches in length but can work with muzzle threads as long as .75 inches in length. Remember your muzzle threads are what’s responsible for your muzzle device’s concentricity with the bore. For the best alignment possible, the longer the better.

Never use spacers and devices that share threads, especially with suppressors, some manufacturers that we won’t name but also sell tuners are advising customers to look past the deficiencies in their products designs and do this, and as a result customers are having baffle strikes and issues etc.

The CHAD is heavy, are you going to offer a lighter version for my long-range hunting rifle/NRL Hunter build?

The CHAD is heavy and robust by design. It was designed for PRS/NRL where overall weight is of no concern to the shooter and is in most cases a benefit if the weight is placed in the right place.

We do however acknowledge this and have lightweight titanium versions of the CHAD planned. Titanium is however expensive and tooling up for it is even more expensive. So it’s something we plan to do eventually but currently we have no eta on it as it will require a significant investment.

When will you be releasing other sizes of the CHAD, the size I need isn’t listed?

Currently the CHAD only comes in 5/8×24 3A UNEF with .264 (.284).

We will add more models and sizes in the next batch. You don’t lose performance by running a .243 calibre on a .264 bore size brake for example, so there’s no point in offering that size and because of that we won’t offer a .243 bore size. The CHAD is designed to have any size bored out up to a maximum of .338 caliber by a gunsmith if needed (.358 inches diameter). So, if you need to have a .284 (7mm) muzzle brake, instead of just running a .308 (7.62mm) you can have a .264 (6.5mm) bored out to that without any dramas, just make sure you always have it bored out an extra .02 inches for bullet clearance like our factory offerings are.

When will you be releasing metric threads?

We have no intention of offering metric threads.

The CHAD is incompatible with M18x1.5 and we will not be changing the design to make it compatible. Please reject heathenism and adopt imperial threads like the rest of the gun community.

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. Physical vapor deposition is characterized by a process in which the material transitions from a condensed phase to a vapor phase and then back to a thin film condensed phase. The coating left behind by the process is 5 ten thousands of an inch thick and many times harder than any heat-treated steel with the properties or a dry lubricant. So, parts hold dimensional accuracy, while improving wear resistance, lowering the coefficient of friction, improving corrosion resistance and improving lubricity, while remaining inert to chemicals. Which is one of the main reasons why we use a DLC coating on the tmb.

The type of DLC coating used for the CHAD produces a flawless and deep matte black colour that is unaffected by CLR, and other extremely harsh carbon cleaning products used in firearms. DLC will not fade or wear off from repeated cleaning cycles in the same way a nitrided finish is destroyed by CLR.

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 it, repair it or organize a full refund. (Warranty does not include coatings after use. If you damage the integrity of your coating ie; scratch it and then soak it in CLR or other chemicals, they can get between the coating and the substrate and remove/destroy the coating. Do not soak your product in CLR or similar chemicals if the coatings integrity is compromised. Take care of your coating and it will last forever, abuse it and it will look like it’s been abused. We also don’t warranty parts damaged from cleaning such as aluminum and brass parts cleaned in chemicals not meant for those materials.)

Do you offer refunds?

We no longer offer full refunds for change of mind.

We are happy to offer refunds minus a 10% restocking fee plus postage fee’s on in-stock products and a 35% restocking fee on pre-ordered products. Please be aware of lead times before making purchases and email for confirmation if unsure. Pre-ordered products wait times are 2-8 weeks before shipping and in-stock items ship within 1 week. If your order/pre-order falls out of these lead times, we accept fault and will offer a full refund.

Do you have any dealers or only sell direct to the public?

We are in the process of setting up more dealers in USA, Canada and Europe (email us for updates on if we have a dealer in your country, this situation is constantly changing as demand grows). If you are interested in becoming a dealer, please contact us to discuss.

Our current dealers and distributors are linked below:

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.

The URL withoutwarning was taken so we added strike to it. So strikewithoutwarning is just the websites URL. Yes, everyone calls the company strike without warning but that is incorrect and always has been. Get it right, nerds.

What targets are used in the tuning 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.
