LMT FULL-AUTO 5.56 BCG

Full Auto Bolt Carrier Group, 5.56×45 (.223)

The L7D3 is the perfect BCG for a Mil-Spec build or as an upgrade from sub-par equipment. LMT Defense has made the full-auto M16/M4 BCG and it's components for years as replacement parts for the United States hard working war fighters and others that need reliable equipment. These BCG’s are standard equipment in all of our complete full auto weapon systems. Works well with both suppressed and unsuppressed weapon systems.
