I own the whisper. Very nice barrel, but not a lot said about it. It is not rifled, but there is a version of it called the twister that is. I am not sure if the apex2 would fit though, and if it did you would definitely have to do a tape mod. But again, is is a very nice barrel even without the apex.

Hey Jaime,

Respectfully, how would rifling not work to impart spin on a paintball?

"Rifling, (besides increasing the chance of shredding a paintball) would impart a spin to a ball around its long axis. This spin serves to stabilize the projectile, improving its stability and accuracy." Would it not?

A paintball can really be equated to a musket ball. Both aren't exactly spherical, and a musket ball greatly benefited from a rifled barrel.

Rifling to me makes sense as an improvement. However I defer to your experience, could you elaborate why you'd think its just a gimmick?

You are correct that rifling will improve the stability of the ball. The only problem though is that your comparison just doesn't work.

First: A musket ball is solid and a paintball is a shell will mostly liquid inside and a small pocket of air. So if it did spin the ball it would be off balance and wobble and be utterly impossible to hit anything.

Second: The rifling in a musket is straight and its main purpose is to keep the barrel from getting clogged. It does this by the grooves collect the carbon build-up from the powder.

Your correct that at first it seems like a good idea but i just don't buy into it.

Well, just to be the devils advocate:

1.) Neither paintball or musket ball are homogenous in composition. It could be argued that you would have even more wobble with a non-rifled barrel. As for it being impossible to hit anything. It already is nearly impossible to hit anything with a smooth bore barrel anyhow. If it works for the rest of the ballistic world (arrows, cannon balls, shuttle cocks [badminton], crossbow bolts, and even First Strike paintballs) why would negating one of the the variable axis be a bad thing?

2.) Rifling wasn't created to keep barrels clean but to impart spin and negate a variable in accuracy. Especially since it was invented around the 15th century I don't think cleanliness was their primary concern, more like accurately creates holes in someone they did not like very much.

Either way, if you don't buy into it, that's cool.

you see kids. this is the reason you should stay in school. simple understanding of physics and this argument would not even have started.

Anyhow i believe this thread was about the Apex? how about you take that rifling vs non rifled stuff elsewhere? and as a side note, the rifled barrel of a musket was underbored so the ball was forced to change shape and since it was not spherical when leaving the barrel it would not tumble while spinning.
