It’s quite normal to attach a suppressor to their gun’s threaded barrels to reduce the noise coming from their gunshots. However, installing such devices on non-threaded barrels is relatively different. Most people rely on gunsmith professionals to do this task.

But why should you spend more money on something that you could do? Here’s how to attach a suppressor to a non-threaded barrel. 

1. Prepare the necessary items

The first thing you need to do is to ensure a safe, open, and clean workspace area before attaching the suppressor/silencer. You don’t need to have a specific room to use, as long as it is large enough to make room to continue to the next steps. You’ll need a non-threaded suppressor, your non-threaded barrel, and your work area. You can use the floor or a long table as long as you clear it out. 

2. Make sure the weapon is completely unloaded

Do not start attaching your suppressor unless you have unloaded your weapon, as it can jeopardize your safety and the product. To unload your weapon, put it on your working table or workspace. And then, carefully take out your gun’s magazine. 

Next, take out the ammunition one by one. Then, check your gun’s chamber to make sure it’s empty. We recommend putting away the ammunition/bullets in a safe location to secure them. Now, you have successfully unloaded your gun.


3. Disassemble your gun

After successfully unloading your weapon, the next step would be disassembling it. Some weapons or firearm products come with a manual from their manufacturers. However, in case you lost your manual, you can still find an uploaded manual online for the instructions. You may check out the official website of your gun manufacturers to ensure that the manual you’ll be following gives an accurate step-by-step process. 

You will also need the right tools/equipment to disassemble your weapons. Well, you may not need to disassemble your rifle part by part, but you’ll need a gun vise to secure your rifle when doing this process. 

Remember to open the muzzle before putting it on the bench vise, which attaches directly to a workbench to hold the workpiece during operations. [1] The gun vise will secure your gun’s place regardless of its barrel diameter or threads, so you won’t need to hold it the whole time you’re attaching the suppressor.

4. Attach the suppressor 

Since you are using a non-threaded barrel, you will need an adapter to lock the suppressor in place. This way, it won’t slide off the barrel’s muzzle. We suggest using a non-threaded adapter for your non-threaded barrel. However, you may also use taper pins, barrel bushing, or locking pins to secure your muzzle devices or any non-threaded barrel suppressors. 

Whatever locking device you’d use, you have to ensure that these tools will reach your barrel without threads before disassembling your firearm. To do this, you must take the spring and slider parts out from your gun. Then, put your adapter and tighten its screws around the barrel without thread. If you already made sure that you have placed the adapter properly on its mounting system, screw it on the muzzle of your barrel without thread. Learn how to time your muzzle brake here

5. Apply a metal bonding solution

After screwing the adapter on the non-threaded barrel to secure a safe place for the rifle flash hider or suppressor, you can now apply a metal bonding solution. Put the metal bonding solution outside the muzzle. 

After doing this, you may now attach your suppressor/silencer. Twist the adapter around the muzzle. Tighten the suppressor/silencer using enough twist or force, but don’t over-tighten the adapter. And then, let the solution stay for at least 24 hours before using your firearm.

What are the Do’s and Don’ts?

As mentioned above, attaching a silencer/suppressor to a non-threaded barrel may be dangerous in some ways. Some things need to be considered before starting to do this process. First, you need to remember that the suppressors/devices must be securely installed in the muzzle. To do this, we recommend using locking pins or adapters. 

It’s also best to understand that all non-threaded suppressors/silencers have different modes or ways of installation. Some manufacturers require barrel-bushing, the installation of taper pins, or pinging the barrel without thread to secure the suppressors.   

For your safety, we also recommend the unloading of your firearms/rifles before attaching the suppressor or silencer to your non-threaded 458 SOCOM barrels. It is also not advisable to point your gun or rifle at anything, especially people.

Final Thoughts On Attaching a Suppressor Without Threading the Barrel

Most people think it’s challenging to do this process. However, you won’t need to pay an extra dime in hiring a professional gunsmith with the help of these steps. Attaching devices like muzzle brakes, compensators,  suppressors, and silencers to a non-threaded barrel needs to be precise, detailed, and thorough to ensure your safety. 

You will have to put in a little effort with all the work, but you’ll save money and time if you can do this alone. It will also reduce the noise from your firearms/rifles, giving you a better hunting and shooting experience.
