Quickboost provides one pitot tube and two ShKAS 7.62mm gun barrels. Of note is the re-sealable packaging that Quickboost uses that makes the parts easy to review and then stuff back into the package securely. There are no supplied instructions; you simply swap out the kit provided plastic parts with the new Quickboost replacements.
Quickboost has molded the pitot tube and gun barrels perfectly in light grey resin with no apparent bubbles. The Quickboost pitot tube and gun barrels have no mold seams to sand off on these tiny parts, and superior detail of actually hollowing the barrel as opposed to a flat face to drill out.
