It's fairly accurate with Marbalizers on my Tippmann 98 Custom. It didn't break paint, but I was only using proballs and marbalizers.
Weaknesses:
The accuracy wasn't as good as I expected but that was with CO2 and no expansion chamber.
Conclusion:
12" barrel, but that's the only one Lapco makes.
Tippman 98 Custom.
Marbalizers seem to work better than proballs
It's definately better than the stock barrel.
It's about as accurate as an Armson Stealth, but for about $20 less.
I think I would.
