Breek Arms Universal HUB Direct Thread Suppressor Adapter (1/2"-28 to 1.375"-24) - BRK4600 - UPC 812296032111

Product Description

The Breek Arms Universal HUB Direct Thread Suppressor Mount (BRK4600) is a low-profile, ultra-reliable direct-thread adapter engineered to convert any industry-standard 1.375"x24 TPI HUB (Bravo) compatible suppressor into a dedicated direct-thread setup. Precision-machined from 17-4 PH stainless steel and heat-treated to H900 specifications, this adapter delivers exceptional tensile strength, wear resistance, and thermal durability under heavy firing schedules.

Designed specifically for 1/2"-28 TPI threaded barrels (common to 5.56 NATO / .223 Rem / .22 caliber platforms), the BRK4600 features an ultra-slim 0.70" profile that adds only ~0.25 inches of overall length to your suppressor footprint. By removing unnecessary quick-detach mechanics, it significantly reduces front-end barrel weight, eliminates potential wobble or play, and minimizes point-of-impact (POI) shift.

Protected by a severe-duty black nitride coating, the BRK4600 features external wrench flats designed for standard 1-1/4" armorers wrenches, ensuring proper torque application into your suppressor's rear body threads. Whether building a lightweight hunting setup, direct-thread precision rifle, or dedicated home defense carbine, the Breek Arms BRK4600 offers an unyielding, wobble-free mounting solution.

*Armorer Bench Notes & Real-World Staging Guidance:

Fitment Matrix: Barrel Threads: 1/2"-28 TPI | Suppressor Threads: Industry Standard 1.375"-24 HUB / Bravo. Compatible with HUB-pattern suppressors from SilencerCo, Dead Air, Rugged, YHM, Rex Silentium, and others. Note: Always verify bore alignment with an alignment rod prior to live fire.

1. Verify host firearm is completely clear, safe, and unloaded before servicing.
2. Apply high-temp threadlocker (e.g., Rocksett) to the exterior 1.375"-24 HUB threads and torque the adapter into your suppressor housing to 25–30 ft-lbs using a 1-1/4" wrench.
3. Ensure barrel muzzle threads are clean and free of carbon; thread the suppressor onto your 1/2"-28 barrel shoulder hand-tight until fully seated.
