Airsoft GI are impressed with the Magic Box Miracle Barrel as they test it against a tightbore barrel... "We recently received the Magic Box Miracle Barrels in, and we wanted to compare them against the existing barrels on the market. We took a 395 mm Miracle barrel and tested it against the 509 mm tightbore Lonex barrel to see what the effective range was in hitting a man size target. Needless to say, we were very impressed with how the new Miracle Barrels preformed and we hope you are too. Be sure to check them out on our website!"
