Lantac Enhanced BCG DI Side Charger

LANTAC E-BCG® Gen2 DI Side Charger, Enhanced Bolt Carrier Group for .223/5.56 Caliber. This bolt carrier group will not work in standard AR-15 upper receivers. It must be used with a side charging upper receiver. For guaranteed fit, we recommend our LA-N15™ Raven™ Side Charging Billet Upper Receiver.
