I recently had the pleasure of getting my hands on the versatile quick-detach Banish 30 Gold and it has left a lasting impression. It lives up to its promise of being lighter, shorter, and quieter than most suppressors on the market. The build quality is top-notch, constructed from a strong titanium alloy that strikes a remarkable balance between durability and lightweight design.

One of the standout features of the Omega 300 is its versatility in attachment options. SilencerCo’s Bravo-style mounting system provides flexibility, allowing you to choose between direct thread or quick-detach methods using the ASR Mount and ASR Muzzle Devices. Attachment and removal when switching between firearms is quick and easy.

The Omega 300 impressed me with its quiet operation. I experienced very little blowback and it effectively reduced recoil and muzzle flash. The materials used in its construction ensure this can is robust yet SilencerCo strikes a manageable balance between durability, effectiveness, and weight.

While I didn’t experience this, some users have reported bubbling and discoloration of the finish after heavy shooting. Most said that they reached out to SilencerCo about the issue and they took care of it within a few days in most cases. It’s not clear why this has happened with a handful of users but even after sending many rounds through the one I tested, I didn’t experience this at all.

Shortest 300 Blackout Suppressor / Best Suppressor for Hunting

Shortest 300 Blackout Suppressor / Best Suppressor for Hunting:
Banish Backcountry

Caliber: Up to .300 RUM
dB Reduction: 137 dB
Length: 5.5″
Weight: 7.8 oz
Diameter: 1.6″
Installation: Various Direct Mounts
Construction: Titanium
Finish: Cerakote

Weighing in at just 7.8 ounces, the super compact and lightweight Banish Backcountry suppressor is ideal to carry while hunting or while shooting for a long period of time. Though small, its sound suppression is impressive. It managed to reduce the noise to hearing-safe levels across various calibers, which is crucial when hunting when you may not have the chance to put your hearing protection back on before taking your shot. The reduction in recoil was also notable, making it easier to stay on target and take follow-up shots quickly. I did notice a slight shift in brass ejection.

The direct-thread attachment was quality, and I had no issues with installation or removal across several platforms. Though I didn’t experience it, some have noticed minor cosmetic imperfections in the finish, that didn’t impact its performance.

The Banish Backcountry suppressor is an excellent mid-price choice for hunters and shooters who prioritize lightweight gear and effective sound suppression. It’s a reliable companion that enhances your shooting experience while keeping your pack light.

YHM Resonator K

Caliber: .17 HMR to .300 RUM
.300 BLK Barrel Restrictions: 7.5″ or larger
dB Reduction: 142 dB
Length: 4.8″ (5.65″ with QD mount)
Weight: 9.6 oz (12.4 oz with QD mount)
Diameter: 1.562″
Threads per Inch: 5/8X24
Construction: 17-4PH Stainless Steel, Inconel
Finish: Matte Black Cerakote
Includes: 1.375×24 QD Mount, 5/8×24 Muzzle Brake

I put the YHM Resonator K through its paces, and I’m eager to share my thoughts on this compact, suppressor. The Resonator K boasts a low price point yet its performance doesn’t disappoint. The lightweight Resonator K makes it an excellent all-purpose suppressor, and its short 4.8” length complements longer barrels without feeling unwieldy. The overall quality is outstanding, especially considering its relatively low price. The tubeless design incorporates heat-treated stainless steel and an inconel blast baffle, allowing full auto rating built for rigorous use.

This silencer is not going to make all of your guns movie quiet or even quiet enough to use without hearing pro, but the sound reduction is noticeable and impressive for its size and price point. Some users may find that the smaller size results in a louder report, but this is a common trade-off with compact suppressors.

The new end cap design significantly reduces flash signature, making it a viable option for low-light shooting without compromising night vision. Plus, there’s minimal gas blowback, which is always appreciated. I did notice a slight shift in brass ejection, but it didn’t cause an issue for me.

The Resonater K’s versatility adds to its value. Threaded at 1-3/8”-24, its compatible with multiple calibers from .17 HMR to .300 RUM. The quick lock system makes for smooth installation and I had no issues timing the muzzle device thanks to the provided shims. Removing it from the QD can be a bit challenging, and there are reports of carbon lock issues. The tension between the suppressor and muzzle device can sometimes lead to the muzzle device loosening during removal.

Although I didn’t personally experience it, others reported a cosmetic issue of drips in the finish application around the rear exterior splines.

The YHM Resonator K is a solid choice for those looking for a compact, versatile, and reasonably priced suppressor. While it may not be perfect, it provides excellent value for the money.

When I had the opportunity to try out the PWS BDE 762 suppressor I was impressed with its performance and features. As someone who values quality and innovation, the 3D printed titanium construction is a game-changer and this suppressor is built to withstand the rigors of heavy use.

Four removable baffles invite you to fine-tune this suppressor to suit specific needs, whether you’re looking for maximum noise reduction or a more compact setup. It’s great to have this level of adaptability in one suppressor.

The taper-threaded baffles are a smart engineering choice. They prevent carbon locking and loosening between baffles. This design feature ensures that the suppressor stays secure even during heavy use.

In terms of performance, the symmetrical internal baffle notches contribute to increased accuracy by helping to maintain a consistent bullet path. Additionally, the exterior textures on the suppressor dissipate heat mirage effectively, ensuring that your shots remain clear and precise, even during rapid fire or prolonged shooting sessions.

Banish 30

Length: 7″ or 9″
Weight: 11.2 oz or 14.3 oz
Diameter: 1-1/2″
Threads per Inch: 5/8×24
Construction: Titanium

I’ve had the pleasure of using the BANISH 30 suppressor for a while now. I have to say, it’s a reliable performer at a great price point. It’s compatible with a wide range of rimfire and rifle calibers, from .17 to .300 Weatherby. But what really makes this suppressor versatile is the ability to switch between two different lengths. In the 9-inch configuration, it holds eight baffles, but it can quickly transform into a 7-inch setup with six baffles, making it adaptable for different shooting scenarios.

Of course, the most critical aspect of any suppressor is its sound suppression, and the BANISH 30 doesn’t disappoint. Internal testing shows that it can reduce the report of a .308 by a whopping 34 decibels at a minimum. That’s a substantial reduction. Plus, it significantly reduces recoil, making shooting much more enjoyable.

Weight matters, especially when you’re carrying your firearm for extended periods. The BANISH 30’s use of a strong titanium alloy keeps it relatively light. In its full 9-inch configuration, it weighs 14 ounces which is on the mid- to higher range, but the shorter 7-inch setup weighs in at just 11 ounces, which is manageable for maintaining the balance and handling of your rifle.

One standout feature that sets the BANISH 30 apart from the competition is its user-serviceability. It’s easy to take apart for cleaning, whether you use a tumbler, an ultrasonic cleaner, or prefer to do it manually. The Stifle™ baffles are keyed and indexed for straightforward alignment during reassembly. This feature not only keeps your suppressor in top-notch condition but also ensures it maintains its performance over time.

The Can-Clean™ technology is another highlight. Suppressors get dirty; that’s just a fact. However, the BANISH 30’s easy disassembly and cleaning process mean you won’t have to deal with lead and powder residue buildup, which wil affect performance.

Its ease of disassembly and cleaning, reasonable price point, and ability to handle multiple calibers make the BANISH 30 a favorite.

300 Blackout Suppressor Buying Guide

How to Buy a Suppressor

If you’ve talked to anyone who has purchased a suppressor, you have likely heard horror stories about the months long process. It is true that the process takes time, but your part is straightforward and not time consuming. The majority of that time is waiting for ATF approval. The main steps are below. Most dealers and online sites that you purchase from will help you through the process. Some are more hands on than others. Silencer Central, for example, has simplified the process and does as much as possible for you because they know the process can feel overwhelming, if not impossible. If that’s a concern, buying through a dealer like them is your best bet.

1. Confirm that it is legal to own a suppressor where you live.

As of the writing of this article, ownership is not legal in California, Delaware, Hawaii, Illinois, Massachusetts, New York, New Jersey, Rhode Island, or the District of Columbia. A special note for Connecticut hunters: suppressors are legal to use for hunting in every state where it is legal to own a suppressor, except Connecticut.

2. Purchase the suppressor in person or online.

Buy the suppressor and pay for the $200 federal tax stamp. The fee is set by the government, so it’s the same everywhere.

3. Submit the paperwork.

Most dealers will help you with the paperwork throughout the process. Once the dealer you purchase your silencer from has a serial number for your silencer (usually when they have it in their inventory) they will guide you through the process of submitting ATF Form 4 (application for Tax Paid Transfer and Registration of Firearm). Usually this form is  submitted online. You will also submit a passport-sized photo and fingerprint cards. There are different processes for fingerprints, so check the rules in your area.

4. Undergo the background check.

Once Form 4 is submitted to the ATF (usually by the dealer), you will undergo a background check, which is the part of the process that may take several months to over a year. This check includes an examination of your criminal history and other factors to determine your eligibility.

5. Prepare your firearm(s) for your new silencer.

While you wait for approval, prepare your firearm. Use this time to purchase adapters and other accessories like silencer covers. You may also need to send your gun to a gunsmith to thread your barrel. Sites like Silencer Central offer barrel threading service (even if you don’t purchase from them).

6. Take Possession of Your Suppressor.

Once your paperwork is approved by the ATF, you can finally take possession of your silencer. If you purchased online, the retailer may even mail your suppressor directly to your door.

Consider a Free NFA Gun Trust.

You may have heard of a gun trust, but you may have never considered why they may be a beneficial option for you. The primary purpose of an NFA gun trust is to simplify the process of acquiring and possessing NFA-regulated firearms and accessories, by providing certain advantages and flexibility. For example, trusts don’t require fingerprinting and photographs for each NFA item purchase. Most importantly a trust can help protect NFA items from potential legal complications that could arise in the future, such as changes in firearms laws or regulations. They also allow for NFA items to be passed down to family members without additional background checks or tax stamps. Creating an NFA gun trust typically involves working with an attorney. Sites like Silencer Central can help you through the steps of setting one up.

How to Choose the Right Suppressor

Determine How You Will Use Your Suppressor

As we often suggest, begin with the end in mind. Know what firearm(s) you plan to suppress, the type(s) of ammo you will use, and the situations in which you will be shooting suppressed (hunting, home defense, etc.)

Cost

Next determine your budget. Expect to spend around $800-$2,000 for a good quality .300 Blackout suppressor. The price will change depending on construction and features.

weapon durability

Compatibility and Barrel Length Restrictions

Once you know how you will use your suppressor and what your budget is, the easiest way to narrow down your choices is by looking at compatibility in terms of the calibers and firearms a suppressor can be used on. Many suppressors on the market today are versatile and can be used across many different platforms.

You will want to pay attention to any barrel length restrictions. Some suppressors have no restrictions while others have very specific barrel length minimums for certain calibers. Make sure those work for the firearms you plan to suppress.

Size

The right size of suppressor will keep your firearm well-balanced, helping you to maintain control over your firearm.

If you will be carrying your suppressed firearm while hunting, or using it for long shooting sessions, a short, lightweight suppressor is ideal.

You may also want a lightweight suppressor if you are using it on a 300 Blk with a longer barrel. Many shooters will notice every ounce hanging at the end of a long-barreled rifle, especially after firing a few rounds.

Depending on how a suppressor is engineered, shorter lengths may not reduce dB as much as longer options, so that is a trade-off to consider.

Noise Reduction

While suppressors won’t make firearms completely silent (as often portrayed in movies), some can reduce the noise to a hearing-safe level. This can help protect your hearing, especially in situations like hunting. Taking the time to put on hearing protection when you’re ready to take a shot could mean the difference between taking home your prize or missing out completely. If this is important to you, find out the dB reduction of the suppressor for the particular caliber you will be using it with. Many suppressors don’t reduce to hearing safe levels. Regardless, many often still use hearing pro while shooting with them.

Construction and Durability

Silencers constructed from durable materials like titanium and stainless steel alloys can withstand heat and wear from heavy use. Titanium is one of the strongest metals in the world. Not only is its tension strength hard, but the metal also retains some flexibility. [1]

Installation

Be sure that installation is compatible with the firearm(s) you want to use the suppressor on. You may need to purchase additional adapters, a muzzle brake, or even take your firearm to a gunsmith to get your barrel threaded in order to use a certain suppressor. It is even possible to attach a suppressor to a non-threaded barrel.

WHY USE A SUPPRESSOR?

Using a suppressor on a rifle offers several advantages, both in terms of shooting experience and practical benefits. Overall, using a suppressor can make shooting more enjoyable by making it quieter, reducing recoil, and improving the shooter’s comfort and control. Reduced noise and decreased recoil are expected when shooting suppressed, but the reasons to use a silencer go beyond that.

Noise Reduction

No shock here. Like the name suggests, suppressors significantly reduce the noise generated by firing. They are popular among hunters because quieter shots are less likely to startle nearby game. In group shooting or hunting situations, suppressors also allow for easier communication, which is essential for safety and coordination.

While suppressors won’t make firearms completely silent (as often portrayed in movies), some can reduce the noise to a hearing-safe level. This can help protect your hearing, especially in situations like hunting. Taking the time to put on hearing protection when you’re ready to take a shot could mean the difference between taking home your prize or missing out completely. If this is important to you, find out the dB reduction of the suppressor for the particular caliber you will be using it with. Many suppressors don’t reduce to hearing safe levels. People often still use hearing pro while shooting with them.

Reduced Recoil and Increased Accuracy

While all suppressors are engineered a bit differently, most mitigate recoil by redirecting and slowing down the gases expelled when firing a round. Reduced recoil also helps with muzzle rise helping the shooter maintain better control over their rifles, resulting in enhanced accuracy. Less recoil allows for faster follow-up shots, and the elimination of “muzzle flip” helps keep the rifle on target.

Reduced Muzzle Flash

Suppressors are valuable in hunting and tactical situations where stealth is crucial because they also typically reduce muzzle flash. In low-light scenarios, the reduced muzzle flash from a suppressed rifle can help preserve night vision, maintaining your ability to see your surroundings.

Are Suppressors and Silencers The Same?

The terms suppressor and silencer are used interchangeably and both refer to a device that attaches to the barrel of a gun with the purpose of reducing the decibel level of the firearm when it is fired.

The term “silencer” is a bit misleading as there are no devices that will completely muffle the sound a gun makes when fired.

The Gun Control Act states “…‘firearm silencer’ and ‘firearm muffler’ mean any device for silencing, muffling, or diminishing the report of a portable firearm.” [2]

FAQs

Most quality 300 Blackout suppressors today usually have a service life of at least 30,000 rounds. New technology allows modern suppressors to endure high temperatures and long periods of automatic fire. 
The federal tax stamp for a 300 Blackout suppressor or any other suppressor, for that matter, is at $200.

A properly installed 300 BLK suppressor can improve accuracy because it reduces recoil, allowing for faster follow-up shots, and also reduces muzzle rise, helping you stay on target.
