Sons Of Liberty Gunworks 158 Carpenter

At Sons of Liberty Gunworks, we believe the bolt carrier group (BCG) is the true heart of the AR platform, driving the gun’s entire operation. From locking and unlocking to extracting and ejecting, every critical action revolves around the BCG. That’s why we’ve built our BCG with Carpenter 158 steel, ensuring reliability, durability, and longevity in any shooting environment.

Key Features:

• Carpenter 158 Steel Bolt: Manufactured from Carpenter 158 steel, a material known for its superior strength and durability, ensuring the BCG can withstand high-stress conditions.
• Optimized Carrier Key Screws (OCKS): For enhanced carrier key security, our Limited BCG comes equipped with OCKS. These upgraded screws provide peace of mind by ensuring the carrier key remains secure under heavy use, reducing the risk of failure.
• Precision Machining: Every part of the BCG is precision machined to tight tolerances, promoting smooth operation and consistent cycling.
• Rigorous Testing: Each bolt undergoes high-pressure testing (HPT) and magnetic particle inspection (MPI) to guarantee it can withstand the demands of any environment.
• Reliable Gas Key: Properly staked gas key screws ensure long-term reliability, preventing loosening during extended use.

The Sons of Liberty Gunworks 158 Carpenter BCG is designed for shooters who demand the highest performance and reliability from their AR platform. As the central component to your rifle’s function, this BCG ensures that every cycle is smooth and dependable.
