This replacement barrel from RB Model is designed for the recent Italeri Crusader III AA Mk.I (kit #6465) but could also be used on the other Italeri kits with the 40mm Bofors.

As with all RB Model sets there are no instructions or fancy packaging, just the parts in a zip lock plastic bag and a simple B&W label which is not really a problem with this barrel as assembly is very straightforward.

The set has the aluminium barrel tube the brass flash suppressor and two brass collars for mounting to the gun receiver with no cleanup required on any of the parts.

Brass and aluminium barrel parts

The barrel tube is hollowed out slightly and the flash suppressor is fully hollowed out with thin cone edges and small indentations around the base for a good representation of the Bofors flash suppressor.

There is the two brass collars, one smaller with four small indentations around the collar and the larger one to form the barrel mountings with the fit of all the brass parts to the barrel being very precise without any filing or alterations required.

After gluing together the two gun receiver halves (kit parts 35E, 36E) there is the resulting hole designed for the plastic kit barrel. The neck pin on the aluminium barrel is the exact size to fit very snugly into the receiver hole making for very quick and easy assembly.

This is another excellent yet simple barrel set from RB Model with no clean-up required, very good fit of the parts and no alterations required to fit to the Italeri kit gun receiver, nothing could be easier.

This set will add considerable improvement to the kit barrel with nice collar and flash suppressor details.

Highly recommended
