Ocl Dta Precision 5/8x24 to 1.375x24 Thread Adapter

The Otter Creek Labs Precision 5/8x24 to 1.375x24 thread adapter lets you run industry-standard 5/8x24 suppressors on firearms threaded with 1.375x24 muzzles. If you're building a direct-thread suppressor setup and want to minimize added length and weight without compromising rigidity, this adapter handles the job with no fuss. Made from 6Al-4V grade 5 titanium with PVD coating, it tips the scales at just 0.9 oz—a legitimate weight savings if you care about ounces in a precision or hunting rifle.

The design is a second-generation platform, refined from earlier iterations to address real-world usability. Extended wrench flats at the rear give you a solid grip point for installation and removal—a practical upgrade if you swap suppressors or need tool-assisted takedown. The internal geometry has been opened up compared to the previous generation, boosting internal volume while actually dropping weight by 0.3 oz. That's thoughtful engineering for shooters who demand both performance and handling ease.

Direct-thread adapters like this one are favored by precision rifle shooters and hunters who want a compact, lightweight suppressor mounting solution without the footprint of a separate brake. The titanium construction keeps corrosion at bay and handles the stresses of magnum calibers and full-auto fire in military or professional settings. If you're already running 5/8x24 suppressors but have a 1.375x24 threaded barrel, this adapter fills the gap cleanly.

Frequently Asked Questions

Can I use this adapter with any 5/8x24 suppressor?

Yes. The adapter is made to work with industry-standard 5/8x24 threaded suppressors, which is the most common direct-thread suppressor bore size in the industry.

Will this adapter add significant length to my rifle?

The adapter is designed to add as little length as possible to your suppressor system while maintaining a rigid, durable connection.

What happens if I need to remove the suppressor frequently?

The extended wrench flats at the rear of the adapter provide a mounting point for a wrench or tool, making installation and removal easier than earlier designs without wrench access.

Is the titanium construction necessary?

Titanium offers excellent strength-to-weight ratio and corrosion resistance. The material is particularly valued in precision and professional shooting applications where reliability and minimal weight matter.
