Precision Armament K-Brake(TM) Ultracompact Suppressor Brake, OPEN SOURCE(R), 220 Cal (Black)

The Precision Armament K-Brake™ KB-220 Ultracompact Suppressor Brake for .223/5.56 is a cutting-edge recoil-control upgrade engineered for AR-platform shooters who want faster follow-up shots, flatter shooting performance, and minimal added length. Built with Precision Armament’s proprietary CDC™ (Convergent–Divergent–Convergent) bore geometry, the KB-220 efficiently manages gas flow to deliver near full-size suppressor brake recoil reduction in an exceptionally compact, lightweight package while remaining fully hearing-safe. Designed for TiTrex™ Suppressors and other Bravo-pattern compatible systems, this premium front-cap upgrade is ideal for modern sporting rifles, duty carbines, and competition setups. Now available at BattleHawk Armory.

Developed through extensive data-driven research and measurement-based testing, the K-Brake™ platform demonstrated class-leading recoil reduction with minimal sound increase at the shooter’s ear. By reducing muzzle movement and improving shot-to-shot recovery, the KB-220 helps shooters stay on target during rapid strings of fire, competitive stages, training drills, and defensive use. The .223/5.56-specific design is optimized for popular cartridges including .223 Remington and 5.56 NATO, maximizing recoil control and host performance.

Despite its advanced capabilities, the KB-220 adds only 0.165 inches to overall suppressor length, preserving rifle balance, handling, and maneuverability. It installs using Precision Armament’s OPEN SOURCE® front interface (1.420-24 UN), dimensionally compatible with the SilencerCo® Bravo pattern for broad suppressor compatibility. Precision Armament’s proprietary Class 3+™ thread specification resists carbon locking while ensuring repeatable alignment and dependable operation under hard use. Compact, rugged, and purpose-built, the K-Brake™ KB-220 sets a new standard for suppressor-mounted recoil performance on .223/5.56 rifles.
