Aero Precision AR15 5.56 BCG with 9310 Bolt

Aero Precision AR15 Bolt Carrier Group

This is a quality bolt carrier group built to exacting standards for your AR-15 platform rifle. It represents the kind of component that separates a reliable firearm from one that merely functions.

Construction & Materials

The carrier is machined from 8620 tool steel, while the bolt itself is forged from superior 9310 steel. This combination provides the durability and reliability you need in a modern rifle. The M16-cut carrier design ensures proper function across a wide range of AR-15 platforms.

• Black O-Ring Extractor Insert: Improves reliability and ease of maintenance
