Rearden Manufacturing Group Llc Direct Thread Adapter 5/8''X24 Square Shoulder Black

The Rearden Direct Thread Adapter in 5/8"×24 is a no-nonsense mounting solution for shooters running suppressors that feature 1.375"-24 internal threads. Unlike quick-detach systems, direct thread adapters screw straight onto your barrel—no separate muzzle brake needed—which means one fewer component in the chain, less weight, and a cleaner sight picture. This square shoulder model is built tough in black finish and weighs just 0.72 ounces, so it won't throw off your gun's balance or handling characteristics.

Direct thread mounting appeals to dedicated riflemen who value simplicity and repeatability. Once it's torqued down, it stays put; there's no mechanical indexing to fuss with or Quick Detach levers to snag on gear. If you're building a hunting rifle, a precision bolt gun, or a dedicated suppressed AR and your suppressor uses Titanium ASR (1.375"-24) threading, this adapter gives you a straightforward, permanent mount that keeps your setup running clean and tight.

Rearden's DLC and S-line coating protects against corrosion and wear, especially important if you're running this in field conditions or running suppressed fire regularly. The adapter threads directly into your barrel's muzzle—verify your barrel is already threaded to 5/8"×24 before ordering, since this adapter requires that spec to work. It's a simple, durable piece of the suppressor puzzle for serious shooters and hunters who've chosen a direct thread path.

Frequently Asked Questions

What suppressor thread sizes does this adapter fit?

This adapter is designed for suppressors with 1.375"-24 internal threading, such as Rearden Titanium ASR threaded tubes. It will not fit suppressors with different internal thread specs.

No. The direct thread design mounts straight to your barrel—no separate muzzle device is required. Your barrel must already be threaded to 5/8"×24.

Is my barrel thread-compatible with this adapter?

This adapter requires your rifle barrel to be threaded to 5/8"×24. Verify your barrel's threading before ordering; common calibers like .223 Rem and .308 Win are often threaded to this spec, but always confirm with your manufacturer or gunsmith.

Is the adapter made of titanium?
