This is the Mad Bull 6.03 mm Tight Bore Barrel. This tight bore barrel is a quick and easy upgrade to get you more power and greater accuracy.
You can enhance your performance by at least 15% by upgrading from the stock barrel! You will get less air leakage around the BB and a tighter grouping of shots. Airsoft players will be surprised to see the difference in performance in their AEG.  This barrel has a hard coating process, which means that it provides the smoothest inner barrel surface and reinforced structure.
