Aero Precision

Overview

The Aero Precision AR-15 Bolt Carrier Group is designed specifically for the 5.56 NATO caliber, featuring a Nickel Boron finish that enhances durability and ease of cleaning. This finish provides a smooth surface that reduces friction, contributing to reliable cycling and overall performance in your build. Typically, you'll find this BCG in mid-length gas system configurations, making it a popular choice for those looking to balance reliability with a softer recoil impulse.
