Lambda Airsoft lambda01 GBB Hi-Capa 4.3 95mm barrel (4580029080208) Lambda Airsoft is a precision parts manufacturer based in Osaka, Japan. They are particular about their machines, materials, and tools used for manufacturing. Lambda parts are made with CNC tooling and hand-finished by craftsmen. Lambda has 3-axis and 5-axis CNC machines, as well as a Coordinate Measuring Machine (CMM) to precisely measure the geometrical characteristics of parts. These Lambda barrels are made from 304 Stainless Steel, which is far more corrosion resistant than brass. Machining is done by a CNC lathe and then hand-finished. These barrels ship in expandable rigid plastic cylindrical tubes, which is great for storing a replaced barrel. This barrel is 6.01, which optimizes air efficiency and can increase power. Since the 6.01 bore is far tighter than the industry standard 6.08, using high quality and consistently made BB's is of heightened importance. Using misshapen or low quality BB's with a tight bore barrel may cause a compression jam. Total length: 95mm Inner diameter: 6.01mm Material: SUS304 Manufacturing process: High-precision cutting with a CNC lathe Finishing process: Hand-finished by craftsmen Made in Japan
