Wolfpack Armory Recessed Direct Thread HUB Adapter Gen 2, 1/2x28, Black Nitride The Wolfpack Armory Recessed Direct Thread HUB Adapter Gen 2 connects a compatible HUB suppressor to a 1/2x28 threaded barrel. Its recessed shape keeps the mounting arrangement compact, while the Black Nitride finish gives the adapter a clean, dark appearance. This is the 1/2x28 version of the Gen 2 direct-thread mount. For a dedicated host, a direct-thread adapter offers a straightforward connection between the barrel and suppressor. The Gen 2 body includes wrench flats and uses 17-4 stainless steel. The threaded interfaces, recessed profile and finish are the key details to compare when selecting the correct adapter. Shop the Wolfpack Armory 1/2x28 Recessed Direct Thread HUB Adapter Gen 2 at BattleHawk Armory. Match the mount to your barrel and suppressor before choosing this configuration. Recessed Profile for a Compact Mounting Arrangement The adapter seats over the barrel, reducing installed overall length by 0.5 inch. Its 1.5-inch outside diameter gives it a broad, low-profile body. The recessed geometry is the defining feature of the RDT design and makes clearance an essential part of compatibility. Gen 2 Stainless Steel Construction Machined 17-4 stainless steel forms the body, with a Black Nitride finish on this version. Gen 2 wrench flats provide a dedicated tool interface. These physical features give the adapter a durable metal construction and a consistent exterior profile without adding a separate muzzle device to the direct-thread connection. Thread Interfaces and Fit Requirements The barrel-side thread is 1/2x28, and the suppressor-side connection is the 1.375x24 HUB pattern, also known as 1-3/8x24. The mount supports compatible SilencerCo BRAVO/HUB interfaces. Check both sides of the connection: the barrel thread alone does not establish suppressor compatibility. The RDT design is intended around a 1.25-inch difference between barrel and handguard lengths. Minimum clearance to the first baffle is 0.95 inch. Suppressor geometry, barrel profile and the suppressor's cartridge rating must also suit the complete combination. Confirm those dimensions with the relevant manufacturers before purchase.
