When diving into the world of .300 Blackout firearms, one question that often pops up is about thread pitches. Specifically, if you’re looking to attach a suppressor or other muzzle device, understanding the thread pitch of your barrel is crucial. Here’s a breakdown that might help clarify things for those of you seeking advice.
Common Thread Pitches
The two most common thread pitches you’re likely to encounter with .300 Blackout barrels are:
5/8x24: This is the standard for many .300 Blackout barrels, especially those designed for use with suppressors.
1/2x28: Although less common for .300 Blackout, some lightweight barrels use this pitch, especially those that might be tailored for different calibers as well.
Why It Matters
Choosing the right thread pitch is essential for compatibility with suppressors:
Suppressor Compatibility: If your barrel is 5/8x24, you’ll need to ensure your suppressor is also compatible with this thread size. Adapters are available but using the correct pitch is generally preferred for performance.
Muzzle Devices: Other muzzle devices also come in various thread sizes, so if you’re looking into options for brakes or flash hiders, this is something to keep in mind.
Measuring Your Thread Pitch
If you’re unsure about the thread pitch of your barrel, you can easily measure it using a thread gauge or caliper. Make sure to do this with the barrel free of any attachments to avoid confusion.
Adapters and Modifying Firearms
In some cases, you might find that your desired suppressor or device doesn’t fit. This is where adapters come into play:
Thread Adapters: Available for both thread sizes, these can allow you to use different devices without needing to rebarrel your firearm.
Modification Considerations: Keep in mind that modifying your firearm can affect its performance and legality, depending on your local laws.

I’ve found that some manufacturers deviate slightly, but 5/8-24 is definitely the most common. There are variants like 1/2-28 for specific applications too.
5/8-24 is a great choice generally, but I’ve seen some custom builds using different pitches. It’s important to ensure your attachments match your pitch to avoid damage!

That clarifies a lot! Range shooting and hunting will really benefit from a reliable suppressor. Don’t forget to check if you have any local laws regarding thread pitch choice!
I don’t mean to be contentious, but I think it’s overblown sometimes. As long as you know what you need, any reputable manufacturer should have clear specs. Just be cautious.
