A set of a tuned aluminum barrel and an outer tube. The barrel is partly rifled near the end. The barrel of this size weighs very heavy! While this product is intended for Dragon's 1/35 kits (6179, 6179X), it might be used, with some modification, for Trumpeter's kits as well.

The difference between Dragon's 60cm-gun Karl and 54cm-gun Karl kits is primarily the gun barrel only, this product may be used for building a 60cm-gun Karl model out of the 54cm-gun Karl kit (well, it doesn't make much sense though).

The sample I obtained has some minor chips inside.

A set of a tuned aluminum barrel and an outer tube, just like the set for the 60cm gun. The barrel is rifled near the end. While this product is intended for Dragon's 54cm-gun kit (6181, 9129), it may be used for building a 54cm-gun Karl model out of the 60cm-gun Karl kits (6179, 6179X) (well, it doesn't make much sense though).

This barrel has only about 50 rifling lines, whereas the real thing has 96 rifling lines. If we are to give 96 rifling lines to this barrel, the pitch between adjacent rifling lines should be about 0.5mm.

These barrels are for Trumpeter's three 1/35 kits. When compared with the barrels for Dragon's kits, the main difference is the lack of the outer tube in these sets. The profile and shape of these sets are also slightly different so that these barrels can smoothly mate with Trumpeter's parts.

Note that although the boxes says these are for "initial version" kits, they are not only for the kit "00208 Moeser Karl-Geraet 040/041 (Initial Version) on railway transport carrier", but can also be used with the kit "00209 Moerser Karl-Geraet 040/041 on railway transport carrier" and "00215 Moeser Karl-Geraet 040/041".

   A review in Track-Link.

The barrel and the sleeve are turned as a single piece. As is with other metal barrles from Jordi Rubio, this is not meant for a particular manufacturer's kit; it can be used for both Dragon and Trumpeter kits. Whichever kit you use this barrel for, you need to slightly modify the kit parts to accept the barrel.

It has rifling threads. The number of threads looks greater than, and their length is longer than the threads in ARMO's barrel. However, they are cut as straight grooves, rather than spiral ones in real guns. I shouldn't complain about this, as I have not seen any turned model gun barrels which has spiral threads.

The set converts Dragon's 60 cm gun kits (6179, 6179X) into a 54 cm gun model. This is a VERY simple set consisting of just a 54 cm gun barrel only. No other parts are supplied. While casting is fine including rifling lines inside the barrel, the rifling lines are represented as convex lines!

As Dragon has released 54 cm gun kits (6181), there is little reason for this set to exist. Maybe you would want to use it for forthcoming Tristar's kit, if it comes only with a 60 cm gun...

This gun barrel does not have full length; it represents only the front half of the real barrel, and the barrel and the outer tube are turned as a single piece. There are no rifling lines inside the barrel. When compared with the plastic barrel in Dragon's kits and ARMO's turned barrel, its outer profile is slightly different from and is slightly ticker than the others. I cannot say which barrel is dimensionally more accurate; but this barrel gives massive impression.
