Nosler 97231 Muzzle Adapter for 33 Cal, 5/8"-24 TPI Thread Pattern

The Nosler 97231 Muzzle Adapter for 33 Cal is a direct-thread mounting solution designed for hunters and shooters running Gen 1 Nosler suppressors on rifles with 5/8"-24 TPI threaded muzzles. If you're looking to attach a suppressor directly to your rifle's muzzle threads without using a brake, this adapter replaces the factory Nosler brake and threads straight onto your barrel. It's a straightforward way to integrate sound reduction into your setup while maintaining the integrity of your Nosler suppressor system.

This adapter works with several Nosler suppressor models, making it a practical component for shooters who own one of those cans and need a simpler, cleaner muzzle interface. The 5/8"-24 TPI thread pattern is common across modern rifle calibers, so if your barrel is already threaded to that specification, installation is simply a matter of screwing on the adapter and then threading your suppressor over it. No tools, no fuss—just direct mounting.

One thing to note: this is a Gen 1 (non-HUB) adapter, so it won't work with Nosler's newer H series HUB-compatible suppressors. Check your suppressor's generation and model before ordering to make sure you've got the right match.

Frequently Asked Questions

What Nosler suppressors work with this adapter?

This adapter is compatible with the following Gen 1 Nosler suppressors: SR-22Ti, SR-22ALTi, SR-30K, SR-30Ti, and SR-30ALTi. It is not designed for H series HUB-compatible suppressors.

Will this work on my rifle?

Yes, if your rifle has a 5/8"-24 TPI muzzle thread. This is a standard thread pitch found on many modern centerfire rifles. Check your barrel's thread specification before purchasing.

How does it mount?

The adapter threads directly onto your muzzle threads in place of the standard Nosler muzzle brake. Your Gen 1 Nosler suppressor then threads over the adapter using the integral left-handed threads on the rear of the suppressor body.

Do I need any special tools to install it?

No special tools are required. The adapter simply threads onto your muzzle, and your suppressor threads over it from there.
