[QUOTE="Swiftkill, post: 1946655, member: 104167"] Theres a huge difference between a ported barrel like Magnaport or a Compensator with an expansion chamber like a JP Brake or Miculek or any screw on compensator. I like to experiment and try different brakes unless you go with a KNOWN compensator that will forever stay on your gun, I wouldn't get it "blended".
