The Raven 6.01+ Inner Barrel from PDI-Japan is now available for the Tokyo Marui Compact Carry Fixed Slide Gas Pistols such as the LCP and Bodyguard 380... "The CS barrel is a cheaper version of our high end SUS barrels and has an inner diameter of 6.01mm+ that give high FPS. The tolerance of the inner diameter has been changed from 0.002mm to 0.007mm compared to the SUS barrel barrel, achieving a lower price.

With regards to other dimension tolerances, the CS barrel is of the same high quality as the SUS barrel."
