You should take a look at this:
''The ORGA Magnus 6.23mm WideBore barrel increases accuracy and trajectory by reducing barrel friction and inner barrel bouncing. The width of the barrel ensures that hop-up spin is constant and consistent when it exits the barrel. This allows for precise, long range shooting, with 60-70 meter accuracy at under 1J.''
The combination of the inner barrel, Ho-up, bucking and nub is also important.
Good quality and matching component is the key.
