Solar Eclipse barrel - There is a micro hump (0,04 mm) inside inner barrel, which holds BB in right position. BB has smaller contact area. Result is less friction in the first phase of shot and better centering for BB in the barrel, so smaller hop-up pressure settings will be enough, the nozzle and BB are better centered also and due to this all features its improving a power of BB slightly.

Double I/D - Double inner diameter. This barrel combines advantages from both types - tight bore and wide bore. Most of the lenght is tight bore, precision 6,03 mm, for optimal air seal and power and the end of the barrel is wide bore 6,35 mm to reach better stabilisation and accuracy.

Air cushion - Grooves in the end of the barell optimalizing the air flow and creates "air cushion" around the BB. Due to this, the BB achieve "front guide" function, so its stabilized also after leave the barrel.
