Details:

Daniel Defense is one of the most premium and high-end brands when it comes to AR rifles and their accessories. Most of their parts meet or exceed military specifications, and the Daniel Defense 5.56 Bolt Carrier Group is no different.

Better Than Mil-Spec

The Daniel Defense 5.56 Bolt Carrier Group has an M16 profile with military spec dimensions. It is made from high-quality steel and is chrome lined and heavy phosphate coated to prevent corrosion and improve its reliability. The bolt is high pressure tested and magnetic particle inspected to ensure there aren't any microscopic imperfections or cracks in the metal. The magnetic particle inspected is also shot-peened to ensure strength and durability.

Properly Staked Gas Key

The gas key is one of the most critical parts of any bolt carrier group since it takes the force of the redirected gasses from the barrel. The Daniel Defense 5.56 Bolt Carrier Group has a properly staked gas key. This ensures that the bolts holding it in place don't move or get loose even after thousands and thousands of shots are fired.
