Rearden Manufacturing Group Llc Direct Thread Adapter 1/2''X28 Square Shoulder Black

The Rearden Direct Thread Adapter 1/2"x28 is a straightforward mounting solution for suppressor users who want to skip the muzzle device entirely. This square-shoulder adapter threads directly onto your barrel, providing a clean, no-compromise interface for suppressors equipped with 1.375"-24 inside diameter threading. It's a no-frills approach: thread it on, attach your suppressor, and get downrange without extra hardware or adapters hanging off the end of your gun.

Direct thread mounting appeals to shooters who value simplicity and a compact overall package. By eliminating the need for a separate muzzle brake or flash hider, you're reducing weight, complexity, and potential points of failure. The 1/2"x28 thread pitch is a common standard on rifles and precision rifle platforms, making this adapter applicable to a wide range of barrel profiles and calibers in that thread size family.

Rearden's adapter is finished in black DLC (Diamond-Like Carbon) coating, a hard, durable surface that resists wear and corrosion under field conditions. The compact square-shoulder design keeps the package tight at the muzzle while providing a solid seating surface for your suppressor. Weighing just 0.72 ounces, it adds minimal heft to your setup.

Specifications

Frequently Asked Questions

Will this work with my suppressor?

This adapter is designed for suppressors with 1.375"-24 inside diameter threading. Check your suppressor's specifications to confirm compatibility before ordering.

What barrel thread size do I need?

This specific adapter is 1/2"x28. Make sure your barrel is threaded to this specification. If your barrel uses a different thread pitch (such as 5/8"-24 or 9/16"-28), you'll need the corresponding Rearden adapter for that size.

Do I need a muzzle brake or flash hider with this?

No. The direct thread adapter mounts straight to your barrel, eliminating the need for an additional muzzle device. This simplifies your setup and reduces the overall length at the muzzle.

What's the DLC coating?

DLC (Diamond-Like Carbon) is a hard, protective surface finish that resists corrosion, scratches, and wear from field use and suppressor removal cycles.
