Unicorn Airsoft's 138mm 6.03mm tightbore inner barrel fits most AEG rifles with short-barrel platforms or CQB builds. The 6.03mm bore diameter creates a tighter air seal than standard 6.08mm barrels, which improves shot-to-shot consistency and accuracy. It's stainless steel with a Nitrolon coating that reduces friction and helps stabilize BB flight. This barrel sits on the hop-up chamber in front of the gearbox, so installation doesn't require splitting the gearbox shell. It comes as the barrel only.
