I bought this barrel today at the field before I played and, well, IT KICKS @$$!!!!!! You see, I have used a tru-flight barrel on my T98c ever since I bought the gun, and it sucked. I coudn't hit jack with it. Today in speedball I popped out of my bunker and... BAM shot "Spyder Man" right in the mask. The next couple of games were about the same.
Now here's the stuff you actually want to know:
VERY light weight
Acurate, even with the length being 12.5 inches
Had no balls get stuck in barrel, but one did break, but that's tippmann's fault.
Quiet
Weaknesses:
Nothing really, but its a little thin and it is not really a 2 piece, though it looks like it.
Conclusion:
For the price, definitely. Even at $70 at the proshop, its great. And you can get them for around $50 on the net. Definitely buy this barrel if you have had troubles with "economical" barrels. I am giving it a 9 out of 10 because I believe everything can be improved on.
I use it with my sheridan (the devil"s machine) and I have observed a big amelioration on the accuracy side.
Weaknesses:
nothing to say
Conclusion:
I used it on above 6 games and it's a very good barrel worth the price
the best in it's price range
it works well with splattball
the only reason that I brake balls it is because my sheridan is to late.
I compare it to CP barrels
Great barrel. Use a 12" on my Shutter. Bore is fairly large with is good for the Zap paint my home field uses. Only broke one ball due the barrel and that was because it became loose.
A couple of shots upside down no paint and it cleared itself out.
Porting can be a pain to clean but it quiets down the loud Shutter
Very light!
Overall great barrel.
Weaknesses:
Accuracy is great short distances..Lacks alittle on the long range stuff. Not a big deal as I am not using a $1000 gun and I am sure that causes problems too. Overall
Like the others say becarefull when you dive into a bunker ..As this barrel isn't
that thick skinned.

Good accuracy for the price...No paintbreaks at all. Light and
no one else has mentioned this but I think it looks cool..
I shoot a pre-96 Autococker, nitro, Custom Brass Valve (for higher air flow), KAPP Nelson Spring hammer kit, 10-Hole Hi-Flow Venturi Bolt, 450PSI gun pressure.
I was impressed by it's accuracy out to long range. It scores a perfect 10 in this category! Even though I'm a forward player I was able to send some very accurate shots across the field (~150 feet) and hit an exposed noggin.
This barrel is also extremely quiet, I could barely hear my own gun firing.
Lastly, I had one break because of a short-stroke and I'd say it cleaned itself almost completely out in about 20-30 shots.
Weaknesses:
It loses points on air efficiency. I had to screw in my velocity adjuster about 6 turns after changing from my 10" SS DYE barrel. This wasn't bad at all though since I'm not really concerned about efficiency over performance. :)
The big problem I had with this barrel was that it is VERY LIGHTLY built. It adds a minimal amount of weight to your gun because of its light construction, but it can't take any rough handling at all.
I had the misfortune of losing my balance and falling forward in deep mud (our speedball field has a spring) and planting my barrel right into it. Now I can't see how mud could do to any other barrel what happened to this one. The front of the barrel had several deep gouges as well as one gouge that bent visibly INTO the barrel. This did not affect the accuracy at all, but I was quite annoyed about this happening to a brand new barrel. I filed the edge down between games and now I'm happy again.
Conclusion:
If you are looking for a great shooting, inexpensive and extremely quiet barrel, and you aren't rough on your equipment, I'd definitely recommend this one for the Autococker.
I give the barrel a 10 in accuracy, a 5 in air efficiency, and a 4 on durability. I don't think it can take much punishment, but you can't go wrong for the price. So overall it's an 8!
I recently added this 14" barrel to my Nu-Line Bruizer Wiseguy 2 and the difference was amazing. I got the acuracy at distance that I had been missing and was picking people off through small openings in trees and bushes. I am very happy with this barrel!
Weaknesses:
The only draw back to this barrel was the length, but that isn't the fault of ACI. I planted it in the dirt a couple of times but there were no performance problems.
Conclusion:
The price of the barrel is good at $70, and is definately worth the price. I used a similar 14" Dye barrel before and I noticed that the ACI barrel performed just as well at a lower price. I tried several different paints in the barrel from cheep to expensive and have not broke a ball or had any accuracy problems in two full day outings. The barrel is also light weight. I would definately recomend this barrel to anyone looking for an affordable, well performing barrel.
