The K-Brake™ ultracompact suppressor brake, is a breakthrough in compact recoil control. Developed through a rigorous, data-driven program, this suppressor brake uses proprietary CDC™ (Convergent–Divergent–Convergent) bore geometry to deliver near full-size suppressor-brake recoil reduction in an exceptionally short, lightweight form—while remaining fully hearing-safe.

CDC™ is a precisely tuned internal profile that manages gas expansion within an ultrashort volume, maximizing recoil-reduction efficiency with minimal sound trade-off. Instrumented testing using a ballistic recoil pendulum and high-fidelity acoustic measurements demonstrated the highest observed recoil-reduction gain relative to sound increase when evaluated against multiple competing benchmark suppressor brakes. When tested on a TiTrex™-300 suppressor with a .308 Win platform, the K-Brake™ suppressor brake delivered a 67% increase in overall recoil reduction compared to a traditional front cap, with only minimal change in sound pressure at the shooter’s ear. Additional testing confirmed that this performance scales effectively across centerfire rifle cartridges from .17 through .36 caliber.

Designed for real-world use, the K-Brake™ suppressor brake excels in hunting, competition, and tactical applications—especially on hard-recoiling cartridges where recoil control directly impacts accuracy and follow-up speed. Caliber-specific versions of the suppressor brake further optimize performance when matched to the host rifle.

Despite its performance, the K-Brake™ suppressor brake adds just 0.165 inches to overall suppressor length compared to a standard front cap. The attachment installs via Precision Armament’s OPEN SOURCE® front interface (1.420–24 UN), which is dimensionally identical to the SilencerCo® Bravo-pattern interface—allowing compatibility across a wide range of suppressor systems. Manufactured using Precision Armament’s Class 3+™ thread specification, the attachment resists carbon locking while ensuring accurate, repeatable alignment under heavy use.

Compact, rugged, and uncompromising, the K-Brake™ ultracompact suppressor brake sets a new standard for suppressor-mounted recoil performance.

Key Features

  • Developed through rigorous, measurement-driven R&D to deliver near full-size recoil reduction in an ultra-compact design with minimal sound trade-off.
  • Using proprietary ultrashort CDC™ internal geometry to optimize gas flow, delivering class-leading recoil reduction with minimal increase in sound pressure.
  • Delivers a 67% recoil-reduction increase over a traditional suppressor front cap while maintaining hearing-safe levels, with performance that scales across centerfire cartridges from .17 to .36 caliber.
  • Adds just 0.165″, while preserving balance and improving control.
  • Fully compatible with the SilencerCo® Bravo interface.
  • The proprietary Class 3+™ thread design provides maximum clearance for reliable operation while maintaining superior bore alignment.
  • Caliber-specific designs are matched to the host rifle to maximize recoil reduction while minimizing sound increase.

Benefits

  • Faster follow-up shots and improved control in hunting, competition, and tactical use.
  • No tradeoff between recoil mitigation and the TiTrex™ suppressor suppression performance.
  • Minimal impact on rifle balance and handling thanks to the compact form factor.

Typical Use Cases

  • Precision shooters who want reduced recoil without sacrifice to sound signature.
  • Hunters using ultralight setups where length and weight matter.
  • Tactical or duty users who need faster follow-ups in a compact package.
  • Enthusiasts upgrading suppressor performance without increasing system length.
