    Our take:  This outer barrel set is crafted from aircraft grade aluminum and serves as a perfect upgrade part.  This set comes with a CQB outer barrel and 273mm tight bore barrel that measures 6.03mm in internal diameter, providing maximum accuracy and increased FPS.  Because these barrels are precision crafted, only high quality, precision grade BBs should be used with this inner barrel.  Professional installation is recommended for anyone unfamiliar with installing a new inner barrel.  The super slick performance finish strengthens and protects these barrels, while reducing friction (conserves velocity & back spin).  This simple upgrade set will result in improved accuracy and is perfect for CQB AEGS or replacing old multi-piece outer barrels.

    Note:  This outer barrel set is ready to use right out of the box, though professional installation is recommended/may be required.  Please use only ultra high-quality precision seamless BBs in your gun after installing this barrel, as inferior grade BBs (i.e.  BBs from sporting goods stores) WILL jam inside this barrel.
