1 review for 5.56 10.3 INCH FSB CRANE SPEC BARREL

  1. Marc Maycunich (verified owner)

    Love the ANDROCORP barrels. Have purchased several of the 10.3″. Tried the Crane Spec barrel this time on my everyday/truck gun as I want to run my Dead Air Sandman K on it. Stated might be function problems without suppressor using certain ammunition. I have now run all kinds of ammunition through it without suppressor on and it performs as I expected, flawlessly.
