Tom Harris of Airsoft Obssesed takes the Elite Force HK417 AEG to test the Magic Box Miracle Inner Barrel with it if it indeed, does miracles with your airsoft gun as others claim in their own tests with it... "Tom puts the Magic Box Miracle Inner Barrel, to the test in his Elite Force HK417 AEG. Using a stock inner barrel and hop-up assembly as the benchmark, he compares the Magic Box Miracle Barrel against it in both a chronograph test using .20g Elite Force BBs, and a range test at roughly 45 yards on a 12in x 12in steel trap target using .28g Elite Force BBs.

The range test was not perfect and in hindsight, a vice should have been used to mount the rifle when firing to eliminate any shooter error, but at the time this video was shot, a vice was not an available resource. Despite that shortcoming, Tom does feel these results are valid and provide a reasonable expectation of the performance results other shooters can expect to see once they have PROPERLY installed this barrel in their own Airsoft AEG(s). While the Miracle Barrel used in this video was provided by Airsoft GI, Airsoft-Obsessed.com is under no obligation to promote the sale of these products for Airsoft GI and will receive no compensation or incentive for doing so.

If you're still skeptical about the results, you are encouraged to do your own testing and draw your own conclusions. It is recommended that you have a qualified airsoft technician install your barrel to ensure that your results can be relied upon. There are no particularly special techniques to installation of the Miracle Barrel, as it is very similar to a standard AEG barrel. You simply need to make sure your hop-up is seated correctly and that you have a good air seal."
