Details:

The Aero Precision 5.56 Left-Handed Bolt Carrier Group (BCG) is designed with left-handed AR-15 enthusiasts in mind, offering two finish options that prioritize performance and durability. Choose from the slick, low-maintenance Nickel Boron coating or the tough Phosphate finish—both crafted to ensure smooth operation for left-eject AR configurations.

Built for Left-Handed Shooters

This BCG is made specifically for left-eject AR-15 setups, working seamlessly with Aero Precision’s left-handed upper receivers. The design provides left-handed shooters with improved control and comfort, making handling and ejection feel natural.

Finish Options to Match Your Needs

• Nickel Boron: Known for its natural lubricity, the Nickel Boron finish reduces friction for smoother cycling and increased reliability during extended shooting sessions. It’s also highly wear-resistant, simplifying maintenance so you can focus more on shooting.

• Phosphate: For a traditional matte look and rugged durability, the Phosphate finish provides excellent corrosion resistance and low reflectivity. It’s ideal for shooters who want a reliable, stealthy option that stands up to tough conditions.

Easy Installation and Wide Compatibility

Installing this left-handed BCG is quick and easy. It’s compatible with Aero Precision’s left-handed receivers as well as most standard left-handed AR-15 upper receivers, making it a practical upgrade for any left-handed build.

Whether you’re looking for low-maintenance ease with Nickel Boron or rugged resilience with Phosphate, the Aero Precision Left-Handed BCG offers the flexibility, quality, and reliability you need to enhance your shooting experience.
