The BCI RPD 3" Super Shorty Outer Barrel w/ Front Sight Post is an easy-to-install lightweight barrel for an exciting new look. Incredibly strong and sturdy, it offers three inches of super short barrel length reaching just to the end of the handguard for a real change-up. We shaved almost 4.5lbs of this beast.

Stock barrel weighs 4.6lbs - this one weighs .17lb
