To fit different barrel brands, it can be installed using the barrel clip or the 3 M3X6 screws. Due to a different inner barrel position inside the hop-up, this unit requires inner barrels at least 3 mm shorter than an “AEG” hop-up unit using the same outer barrel, to prevent the inner barrel from protruding beyond the outer barrel. - The “510” outer barrel requires a 507 mm GBB inner barrel - The “420” outer barrel requires a 417 mm GBB inner barrel - The “330” outer barrel requires a 327 mm GBB inner barrel This hop-up unit is compatible with the advanced hop-up kit (SBA-HOP-34).
