pop-up barrel

[IronCore]

You guys have probably heared about the ws66 barrels and I was wondering if they are indeed accurate. Also how hard is it to make an adaptor from that barrel to our old automags (quarter turns). Thanks

[Rokudon]

sorry, i just needed to correct that, its HOP up barrel. applies a spin to the ball. sorry, i cant really help much more. other than these barrels are very long. last i heard they were 16" or more

[justjoshin590]

well from what i hear they have insane range and acuracy, of course you cant buy the barrels seperately, so that pretty much kills it for now, btw i bought a ws66 and its given me nothing but trouble, when it would actually shoot it had horrible accuracy, and the three grooves have to be on the top of the barrel in the 11, 12, and 1 o'clock positions so its difficult to make sure its in the right place

there 14" or 20" they both have the same range but the 20" in more acurate

though dont take my experiences with the gun to seriously, both the armotech customer service and the dealer i bought it from have seen it and say there's somthing seriously wierd with it, the cs blamed me so i sent it to the dealer, havent gotten it back yet

Can someone post a pic.

[Rokudon]

there.. that suks, hop up barrel would be fun to mess with... they should make a bolt operated version

[IronCore]

from what I hear its more realiable than the flatline barrel because of its design. Hopefully somebody could make a deal with warsensor and make similar designs for our marker
I'd definitely pay a little premium for one of these babies.

What does hop up do? I know soem Airsoft guns have it, isnt it where like the barrel is adjustable to get a better size or something?

[Glickman]

hop up is used on airsoft guns to put a backspin on the projectile.

i dont know how well it works on paintballs due to the paint inside, i have seen improvement while shooting airsoft guns with hopup.

its just a flatline, thats all, just another name for a flatline

[justjoshin590]

no its a lot more than "just a flatline" its a lot more efficient since most of the energy isnt lost creating backspin, and it can stiff fire at 300 fps without zinging strait up out of the barrel

[master_alexander]

it would definatley good on a paintball gun , it needs to be long though nut not too long. on airsoft guns it goes like the pic below from the barrel to the target, remember shorter barrel lighter ammo and lower fps with an airsoft gun.

as you can see in the bad picture, it goes up fast and down slow

-flatlines are completely different. they do the same thing though, apply spin to the ball. flatline curves the barrel upwards, making the ball hug the upper edge (due to momentum) and create spin liek that. ball has to hit a "ramp" of some sorts to deflect the ball upwards.
-HOP-UP barrels have a different concept. they applya a backspin to the ball, without the curve. from what i read, the warsensor version uses the grooves to create a pressure difference, making the ball spin (one side has more pressue, one has less). as others say, less velocity picky, and by ESTIMATION probably better on paint as well

[IronCore]

I was behind a guy over the week end with a flatline and that thing is not that accurate, I think because after the ball rolls around the curve it has a tendency to bounce on its side as it leaves the barrel and that messes up the backspin effect. From the looks of it the hopup barrel is slightly different that it continously applies the backspin effect to the end of the barrel or maybe its just my wishfull thinking

[SlartyBartFast]

Didn't the Z-body do exactly that for a mag?

Problem is that you need to use a very big bore barrel for it to work. Bye-bye efficiency.

Both the Flatline and the Hop-Up barrel achieve backspin in the same fashon but their methods are completely different.

True, the flatline is a bent tube that forces a ball to roll along the top surface of the barrel's ID to generate backspin. However the flatline is picky on paint and on the muzzle velocity that the ball is leaving at. For a flatline (and I'd assume for the Hop-Up) the smaller and rounder the paint, the better. Flatlines aren't known for driving tacs, but then how many barrels really are for the kind of range that a flatline can toss paint? Fact-o-the-matter is that no barrel beyond medium to short range will have "ball on ball" consistancy, it's a fact of life and for those that don't believe me, try putting 10 rounds of .308 through the same hole at greater than 500 yards without a bench rest (an example of not everyone being able to shoot that well anyway even IF the equipment is capable of such consistancy). Also, the only time paint is touching any surface of the FL other than the top of the barrel there's either a break in the thing, the paint is huge, or the shooter is jerking causing the shots to go wild.

The Hop-Up barrel still gives the ball backspin by having it roll along the top surface of the barrel's ID, however it does it with air pressure rather than the ball's momentum. Simply, the 3 grooves in the top of the barrel suck the ball up against the top of the barrel. The long explination (well, kinda long anyway) is that the three channels generate an area where the air can move past the ball faster than anywhere else in the barrel. Because fast moving air exherts less pressure than slow moving air the ball essentially has a low pressure system above it which causes it to rise (the same reason why an airplane can generate lift). This fast moving air (or rather the slow moving air around and under the ball) pulls (or pushes) the ball along the grooved surface of the barrel which generates spin on the ball. The ball (after it exits the barrel) gains lift from this spin thanks to the Magnus Effect (the same thing that influences golf balls) and everyone is happy because their paintball can shoot farther than everyone else's (yay!).

Modifications to a twist/lock barrel would involve cutting the exsisting barrel off beyond the twist lock portion and notching the barrel (and cutting it such that it could accept the OD of the Hop-Up barrel) then basically putting a huge clamp on the whole aparatus so the transplanted barrel doesn't move around. End result, lots of time, effort and bloody knuckles for something that probably won't work or requires more machine time and experience than the average paintball player (which is generally 0 hours).

And yes, the Z body mag did have a kind of hop-up system on it but it didn't work and most people who have the Galactic body didn't use it (it was adjustable)
