Bt Sd-145550 Direct Thrd Dt Adapter 5/8X24

The B&T SD-145550 is a direct thread adapter designed for shooters who want to attach suppressors or other direct-thread accessories to barrels threaded 5/8x24. This lightweight hub adapter bridges the gap between your barrel and compatible silencers, giving you a quick-disconnect alternative to permanently installing a suppressor on your host rifle. If you're building a precision rifle, upgrading an existing firearm, or running a suppressed setup across multiple hosts, a direct thread adapter lets you swap between fixed and removable configurations with minimal hassle.

B&T Firearms engineered this adapter as part of their modular suppressor ecosystem. The 5/8x24 thread pattern is one of the most common precision rifle standards, making this adapter compatible with a wide range of mid-caliber and large-caliber suppressors designed for that interface. The direct-thread design means you're mounting straight to your barrel—no additional muzzle brake required—which keeps your setup compact and reduces point-of-aim shift when you remove the suppressor.

Whether you're a long-range hunter, precision rifle competitor, or tactical shooter, this adapter gives you the flexibility to run your rifle suppressed or unsuppressed without permanently threading your barrel or adding bulk at the muzzle. It's built to B&T's standards for durability and dimensional accuracy, ensuring a solid, repeatable connection every time you mount or remove your silencer.
