I am making a list of parts to buy to build an Impulse, not stock then upgrade, I'm talking buying everything putting it together and hopeing to God, Allah, Buddah, or Yeaweh(I don't know how to spell it, but its the jewish term for God) that it'll not leak, and then shoot paint without chopping paint. Anywho I was planing on getting one of the barrels from Smart Parts, unless someone can name a better one. So what kind should I get, what barrel length, and what bore size(I'm pretty sure that .68 is the one to go with, assuming you can't get a bore size kit), and if you can get front and a back, what kind of each should I get.
