one piece only =\
This barrel was used with my Spyder Shutter. They went well together. It's definately a nice looking one piece barrel. It is also very accurate, surprisingly. The only thing i didnt like was that it was loud compare to a stock spyder barrel. But honestly, this is the best one piece out there because of its price. If youre gonna spend more than $40 on a barrel than get a 2 piece barrel. You'll notice the difference. And you'll be a much happier person. But if youre gonna get a one piece barrel, than the System X one piece barrel is the way to go.
if youre in the market for a one piece aftermarket barrel....BUY THIS ONE...otherwise dont spend your money on anything else
