Nowadays ”one barrel, many bores” is in. Psychoballistics has released a new barrel with variable bore named ’Aradus’. It’s possible to change the bore size by twisting the barrel.

There are five bore sizes available, namely .676, .680, .684, .688 and .692. The price of the barrel is USD 99.95, and at the moment the barrel is available for Spyder, Tippmann, Autococker and Angel threads. Barrels for other markers will also eventually be available.

A lock is available for tournament players, with which one can lock the bore size so that it cannot be switched on-the-fly.
