4BROS Modular Chest Rig

4BROS Modular Ambidextrous Chest Rig System – Built for Performance, Comfort, and Modularity

The Four Brothers Holsters Modular Chest Rig is designed for shooters who demand flexibility, strength, and total control of their gear setup.

Built for the Hunt, the Workday, and the Trail Ahead

Whether you’re tracking game at dawn, clearing brush on the job, or hiking deep into the backcountry, the 4BROS Modular Chest Rig System keeps your essentials exactly where you need them—secure, stable, and ready. Engineered from dual-layer Tegris and designed around our trusted OWB holster lineup, this 4-point chest rig delivers all-day comfort and confidence no matter what the day demands.

Made for Real-World Use

For Hunters:
Move through brush, climb into blinds, and track quietly with your firearm secured to your chest. The 4-point harness keeps weight balanced and your draw consistent, even when layered over heavy gear.

For the Worksite:
Built to handle long hours and hard use, the dual-layer Tegris backer and rubberized straps stay put while you bend, lift, and move. Durable enough for field work, surveying, or equipment maintenance.

For the Hike:
When miles turn to elevation, comfort and security matter most. The adjustable 0°–90° mount lets you carry how you want, while keeping the firearm secure and close to your body.

One System, Endless Utility:
Whether it’s hunting season, a long day on the job, or a weekend on the trail, the 4BROS Chest Rig adapts to your life outdoors—ready for whatever comes next.

Key Features:

• Adjustable Mounting Angles: Configurable from 0° (vertical) to 90° (horizontal) in 20° increments for personalized draw preference.
• True 4-Point Contact Design: Enhanced stability and comfort—no pressure points or strap slip like common 3-point chest rigs.
• Dual-Layer Tegris Construction: Rigid, lightweight, and precision laser-cut for superior strength and durability.
• 1.5” Rubberized Straps: Provide traction and friction against clothing for a secure fit during movement.
• Fully Ambidextrous: Can be assembled for right- or left-handed use using the included hardware.
• DIY Assembly: Ships unassembled to save you money and build familiarity with your gear—includes all hardware, threadlocker, and full instructions (written and video).
• Made in the USA: Designed, laser-cut, and packaged in Logansport, Indiana.

MANDATORY STEP:

Check all hardware after initial setup for correct installation and again after your first on-body test session. Apply the included threadlocker to prevent loosening hardware. This is a mandatory step for this system to work correctly.
