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!
