Product Description

The Aero Precision M5 Complete Bolt Carrier Group (BCG) is a premium firing mechanism purpose-built for big-bore AR-platform rifle builds chambered in .308 Win, 7.62x51mm NATO, 6.5 Creedmoor, .338 Federal, and other .308-based cartridges. The carrier is machined from 8620 Tool Steel and features a mil-spec Black Phosphate finish, forward assist serrations, and a laser-engraved Aero Precision "A" logo. The gas key is constructed from 4130 Steel, attached with Grade 8 hardware, and properly staked to ensure reliable function. The firing pin is machined from 8740 steel and hard chrome coated for long-lasting durability. The complete bolt is case-hardened 9310 Steel, Magnetic Particle Inspected (MPI) and High Pressure Tested (HPT), and features double o-rings and double springs on the extractor -- machined from 4340 Steel -- for enhanced reliability. This BCG is fully compatible with AR .308/M5-compatible upper receivers and rifles, and arrives complete right out of the box.
