Colt M4 Commando 5.56 lower assembly with LE prefix is the law enforcement marking. Mil-spec parts kit installed. Authentic Colt markings. Standard mil-spec dimensions throughout. Drops in to any milspec upper without fitting.
LE prefix lower is a collector item at this point, mated to a colt upper for a retro 6920 build. tolerances are exactly what youd expect from colt, takedown pin slip without play but no rattle either. trigger pocket clean
