Luth-AR AR-15 Complete Bolt Carrier Group 223/5.56 Gold

A complete bolt carrier assembly for 223 and 5.56 AR-15s, shipped together as one unit rather than as a bag of parts, so it goes straight into the upper. Luth-AR builds the carrier from steel and heat treats it to Army specification.

The gold color comes from the titanium nitride coating, which is hard, slick and stubborn about letting carbon stick. That means lighter cycling friction, less scrubbing at the end of a range day and a carrier that wipes down instead of soaking. It also makes the inside of the upper easy to inspect at a glance.
