umm...not sure probably the same as most rifled barrels
CORE sharc with this barrel (armson stealth)
All-star ___ DO NOT PUT ZAP IN!!!
good accuracy....its rifled so that puts spin on it and gives more distance good for a snyper!!
doesnt work that well in the cold if u use C02 because it makes the barrel really cold and starts 2 chop paint
this barrel is accurate and has good distance for a snyper....not that good if ur using it rapid cause it could start 2 chop paint. Its mostly used for a person who likes 2 scope people out!!! Buy this barrel if u have the money and u like 2 scope people out
