Aires is constantly adding to the Quickboost line, and here is one of the latest.
QB 48-602 are gun barrels designed to be used with Hasegawa’s 1/48 N1K2-J. As with other Quickboost products, these are meant to be drop-fit replacements for kit parts. The molding on this resin set was extremely crisp.
In comparing these to the kit items they are designed to replace, I found a few key differences. First, and probably the main reason one would want this set, the tips of the QB set are open. Hasegawa’s barrels are sadly molded flush across, with no opening. While in general I am fine to create an opening with the tip of my Xacto and a small drill on ‘standard’ gun barrels, the flared muzzle on these makes that a bit more challenging of an undertaking. So I will happily be using the QB ones instead. Second, the QB barrels just have a much less ‘clunky’ look to them. A quick glance at the photos should help demonstrate that.
