2cm Flakvierling 38 Barrelset
2cm Flakvierling 38 Barrels and Magazines

by: Robert Blokker [ FAUST ]

Originally published on:


The 2cm flak 38 was an improved version of the Flak 30. Rheinmetall Borsig improved the rate of fire of the gun from 120 RPM to 220 and the gun had a lower weight. Still the army and Luftwaffe were never really convinced of the 2cm AA guns with its limited range, certainly when compared to the 37mm AA guns that were made from the 20’s which delivered a larger caliber and effective height range.

Rheinmetall answered to this with a new version of the 20mm by making it a vierling, a development that happened in a very short time. This was enough to make the 20mm Flak competitive again against its 37mm counterpart. The effective height at which it could shoot was 2200 meters and was therefore used extensively against low flying aircraft.

With the market nowadays being flooded with Flak kits, and vehicles that somehow carry flaks, or are towing flaks, it is only logical that every after market manufacturer tries to hook onto the hype and start producing aftermarket details for them. And Voyager is no exception here.


The barrels come in a nice transparent blister package measuring 8 cm high, 6 cm wide and 1 cm deep. Inside you will find two bags; one with 4 PE frets and the other with all sorts of turned metal parts, along with a small instruction sheet. I will refer to the bags as bag “A” and bag “B”

Bag A:
In bag A you will find all the turned metal parts. Its contents consist of 4 x barrels turned out of aluminum, 4 x flash suppressors turned from brass, 4 x shells with bullet, 4 x empty shells and a piece of metal wire.

Bag B:
This bag contains 4 small identical PE frets. Each PE fret has several parts to make the 20mm magazines, the cradle in which the magazine sits on the gun and a small detail part that goes on the barrel itself.


The barrels themselves are really beautifully made, and the detail is absolutely perfect. Voyager even added the textured grips on the barrel which made replacing it on the real gun much easier. The detail of this is very fine so when you are painting this make sure the paint coat is not too thick otherwise you will have the chance that this detail will disappear.

The length of the barrel in real life should be just under 1 meter (barrel to flash suppressor), which in scale transfers to 28.4 (and a bit) mm. Measuring it with a slide caliper gives me a length of 28.51mm which is pretty much spot on.

The flash suppressors are also very well made. The collar that slides onto the barrel has 6 holes. All of them are the same size, where two of them should be a bit smaller. The cone itself has 4 rows of holes, with each row consisting of 6 very tiny holes. I have not come across this combination in pictures. I have seen 3 rows in the cone and 6 holes in the collar and 4 rows with 8 holes in the collar.

The magazines consist of 6 parts each which are, looking at it, not that hard to assemble and should not pose that many problems. The wire that is added in Bag A is used for these magazines as you make the pins out of it that lock the magazines into the magazine cradle on the side of the gun, which is also included in the kit as PE. You can finish the magazines by closing them off with one of the full shells delivered in Bag A, but this is only visible when the magazine is placed outside the magazine cradle.

The Instruction Sheet:
Inside the package you will find an instruction sheet measuring around 8 cm by 12 cm folded up and which is full of spelling/translation mistakes. The spelling/translation errors are not of any influence to the building process but were not really necessary in my opinion. The drawings are very clear, showing which parts you have to cut off and replace. The other side shows the assembly of the magazines and the magazine cradle on the gun. The parts are that simple that even without the instructions you can pretty much assemble it.


Voyager delivers quite an impressive package. Where most manufacturers only supply the barrels with some basic PE to detail them, Voyager takes it a bit further. By giving you a whole package to spice up your 2cm Flakvierling, which they claim does not matter which brand it is.

The details are very nice. I was pretty impressed by the textured grips on the barrel and also the flash suppressor, despite having some details (the cone/collar holes combination) that I have not yet matched with any picture. Also the length of the barrel being pretty much spot on is a big pro for this set.

The details on the magazines are very well cut and should look stunning when on the kit. And the added shells are a nice bonus.

The only drawback of this set I think is the price. Which at € 24.50 is a bit steep. Then again… you get quite a nice set for it which is quite complete.
Highs: Correct barrel length, textured grips on barrel. Nice PE set in a very complete package.
Lows: The price, unknown cone/collar holes combination.
Verdict: Really nice set which will look absolutely great on any 2cm Flakvierling 38.

About Robert Blokker (FAUST)

Started modelling when I was about 7 or 8 years old had a little break in between (school, girls partying) and eventually returned when finding this site in 2002. Main interest WW2 German army, wheeled vehicles and radio and communication troops or every other thing that manages to catch my interest...

Warren ... where did you order them from? US$6.99 is a very nice price!! [/quote] Hi Frank. Lucky Model is where I get all my Voyager stuff from. Free postage makes them irresistable!

Hi! Sounds like just what I need as I complete an old Tamiya Wirbelwind flakpanzer... So off I went to the lucky Model site and could not find any such barrel set. I know I'm not looking in the right way nor location... But. Could somebody please tell me what the Voyager Model item number is- maybe that'll be the missing link I need! Thanks! Bob

Great review Robert Bob, the item # is VBS0137 which Lucky Model is showing as 'available' (so not in stock). That's a great price for a four pack of these barrels.
MAY 16, 2010 - 02:45 PM
The number was in the item ID of the review. I am willing to wait a few months if needs be to save all that money. 24 Euros = US$29....
MAY 16, 2010 - 03:58 PM
Thanks! for the item number! Why am I not surprized to see it is "available" and not "in stock"!

Ola Guys Thanks all for the comments on the review. As for the price... It was based on an Italian Onlinestore. I usually try to search for retail prices in onlinestores but as is already pointed out. There are obviously places where you can get them cheaper. I paid a tenner for it but I bought it from somebody else. 6,99 dollar is a steal for this set

I was not saying anything against you Robert, please don't think I was. Is amazing how much some places think they can gouge us modellers, my LHS is a prime example unfortunately.
MAY 16, 2010 - 10:40 PM
Warren. No problems there I kinda understood that already. But I thought it was a good thing to say where the price comes from... Living in Holland I know all about ridiculous prices... something that sadly is not limited to modelling alone. And I'm always looking for cheaper sources for that reason.

First of all, nice review, Robert! Second, you can't beat that price! I wonder if LM will continue to sell them so cheaply, or if this was a close-out to get rid of stock? LM have told me they don't re-stock Voyager all that often, and Griffon Model has had the edge in marketing their line of Vierling replacement barrels and shields. The same item is $19 from Hobbyeasy.com, so I doubt we'll see that $6.99 price again, LOL! Finally, there's no way to avoid replacing the kit barrels in the Tamiya warhorse Sd.Kfz.7/1 and it really makes sense at this price in the Dragon or Trumpeter versions. The key weakness in styrene is the flash suppressor, which can't compete with brass ones when pre-formed and not something you have to make yourself ala Aber or Eduard PE sets.
