smart parts ion white w/ max flo micro, 14 progressive, qlock, halo b red
Bore size not adjustable
When i first used my ion, it worked great. It shot right out of the box and worked very well. There was one problem, my accuracy was'nt consitent enough. Soon after, i bought a cp single piece barrel 14 inch. That helped a little, but not quite enough. Then, I started to look at smart parts barrels. Most were out of my price range, but there was one that interested me, the progressive. I asked people who had used, and they said it rivaled the accuracy of the all american, so i bought it. When i first used it, it helped a tone. i got three kills thanks to it, and many more that day where accuracy came into play.
An overall great barrel, the best one for it's price as well.
