i'm quite new to the paintball scene and am looking to buy a Hammerhead barrel for my A5, but i don't know about the differences of fin sizes?
What would people recommend?
The fin size is to do with the bore. Looking at the web Hammerhead web size the barrel comes with 3 fins with a choice of different sizes. These are barrel attachments for different sized paintball. If the barrel is to big for the ball you can lose distance, speed and accuracy. As the paintball can be different sizes and can give you a slightly better contol of the ball.
If you are looking at different sizes I would go for a .690, .688 and .686 or .683 as they dont give you a great range of fin sizes the other 2 sizes are .679 and .683
Thanks alot mate, this helps alot, i went and tried a few of my paintballs through the sizer and .688 was the barrel for me, got the hammerhead mofo today, very pleased with it
