ok so last week monday i order a bolt from dezigns i talked too robert and everything is going as planed till i noticed i told him to make a venturi stlye bolt. now my problem is i dont know what the difference is so i need to know if i should tell him to change my order to a open face or keep the venturi i just want what ever one will have the most effect performance wise thanks

venturi with give you a more even push on the ball. but the open face will give you more air flow, which means lower pressure.

[John Rambo]

so it will be more accurate?(the venturi)

[for2nato]

i would say yea the venturi is a little more consistant. but for the difference you might go with the open face for the efficiency,

[John Rambo]

well i already ordered it over a week ago so im sure he already started it. and i would think the venturi version may take a little bit long to make compared to the open faced ones correct

[for2nato]

yea the open faced is a single bore. venturi is alot more drilling
