Aero Precision Bolt Carrier Groups (BCGs) are known for their quality and reliability in AR-15 builds. They are typically made from 8620 steel for the carrier and Carpenter 158 steel for the bolt, with a Black Nitride or Phosphate finish. Features include M16-cut carriers, forward assist serrations, properly staked gas keys, and rigorous testing like High Pressure Testing (HPT) and Magnetic Particle Inspection (MPI). The Black Nitride finish offers reduced friction and easier cleaning.
Here’s a more detailed breakdown:
Materials and Construction:
- Carrier: Machined from 8620 steel, a durable and strong material.
- Bolt: Machined from Carpenter 158 steel, a high-strength tool steel known for its ability to withstand high pressure.
- Finish: Available in Black Nitride or Phosphate. Black Nitride is known for its lower friction and easier cleaning properties.
- Gas Key: Properly staked to prevent loosening, ensuring reliable gas system function.
- Bolt: Includes a Black O-ring insert for the extractor.
Features:
- M16-cut carrier: Provides full auto capability, even in semi-automatic rifles.
- Forward assist serrations: Allow for manual forward movement of the bolt carrier group if needed.
- High Pressure Tested (HPT): Ensures the bolt can withstand high-pressure rounds without failure.
- Magnetic Particle Inspected (MPI): Verifies the bolt is free of internal defects.
- Shot peened bolt: Reduces stress and increases the strength of the bolt.
Benefits:
- Increased Reliability:The robust construction and rigorous testing ensure reliable function in various shooting conditions.
- Reduced Friction:The Black Nitride finish minimizes friction, leading to smoother cycling and potentially reduced need for lubrication.
- Easy Maintenance:The smooth finish of the Black Nitride BCG makes it easier to clean and remove carbon buildup.
In essence, Aero Precision BCGs are designed to be durable, reliable, and easy to maintain, making them a popular choice for both casual shooters and those building more serious firearms
