hey guys this is my new barrel system I had made. inner barrel is SS Ra-Tech 650mm 6.03 that I had them make for me. As of this Monday im Rhoping the barrel. I noticed a lot more improvement over the RA Tech 510mm 6.01. BBs are more uniform past 260ft then before. I'm still hitting 300ft but hop the Rhop will make my grouping a lot tighter
here is a chrono vid still a new RA Tech bucking so fps will vary a lot. enjoy
