Breek Arms Direct Thread Low Profile Hub Adapter – 1/2×28 – Titanium – BRK4600TI
The Breek Arms BRK4600TI (812296032128) is a premium, ultra-lightweight hub adapter designed for shooters who demand maximum performance and minimum weight from their suppressed platforms. In 2026, as the “HUB” (1.375×24) standard has become the industry universal for suppressors, this adapter allows you to convert any compatible silencer into a rock-solid direct-thread system. Machined from Grade 5 Titanium and finished in a durable Black DLC (Diamond-Like Carbon), the BRK4600TI weighs in at a fraction of standard steel adapters. It is specifically threaded for 1/2×28 muzzle profiles, the standard for 5.56 NATO/.223 Rem and 9mm carbines.
The standout feature of the BRK4600TI is its low-profile design. By minimizing the distance between the muzzle and the first baffle, it keeps the overall length of your firearm as compact as possible while maintaining a perfect concentric seal. Additionally, this adapter is Breek-LOK 3QD compatible, allowing it to integrate seamlessly with Breek Arms’ proprietary quick-detach shielding system. This provides a versatile foundation: use it as a standalone direct-thread mount for a lightweight precision build, or pair it with Breek-LOK accessories for tactical modularity. For the weight-conscious shooter looking to “bulletproof” their suppressor interface, the BRK4600TI represents the pinnacle of titanium engineering.
Includes: (1) Breek Arms Titanium Low Profile Direct Thread Hub Adapter (1/2×28).
