GunLab’s Cutaway Gerät 05

008

It seems that if you want a reproduction late-war German experimental rifle design, you should get in touch with GunLab’s Chuck. Besides his VG-1-5 project which we’ve covered several times in the past, he also mentioned a year ago that he was doing a run of 60 Gerät 05 rifles. These were roller-locked gas-operated rifles patterned off the Gerät 03, which was itself a derivative of the G.43/K.43 (and they, in turn, were derivatives of the G.41(W) rifle). They fed from MP-43 magazines, while having a conventional stock layout.

A result of that project was this cutaway Gerät 05 rifle, which is almost certainly a unique specimen:

008 009 010 011 012

For those interested in more information on GunLab’s Gerät 05 project, they can read Chuck’s other posts on the rifle here, here, here, and here. Forgotten Weapons also has a family photo of the roller rifles. While it doesn’t have ever member of the family, it does have most of the experimental ones (reproductions of them, anyway).

By my count, GunLab’s ongoing projects include the VG-1-5, Gerat 06, Gerat 05, and AR-16. That is certainly enough to keep him busy!

    I knew roller delayed blowback and roller locked short recoil operated… roller locked gas-operated is new to me.
    Interesting.

  • Don Ward

    At first blush, it looks kind of like an M1 Carbine.

  • Joshua

    One of the better done cut a ways I have seen.

  • Carlos U.

    So THAT is the AK’s daddy.

    • iksnilol

      At best it is the distant cousin who sorta kinda looks like it.

    • It is unrelated. The great majority of the AK’s design DNA comes from the M1 Garand.

    • Jon

      Carlos, that’s a very good way to demostrate your ignorance.

      • Carlos U.

        Gas piston in the same location, recoil spring in the same location, same kind of sights, same kind of magazine… other than roller-locked vs rotating bolt, pretty much the same thing. Care to enlighten us, Jon?

        • Doom

          Gas piston is different. Recoil spring is different, sights are common notch and post sights. magazine lockup is different. bolt lock up is different. trigger group is different. etc etc etc etc. it is very different…

  • Tassiebush

    Is the roller the shiny bit off the side of the bolt at the back of the cutaway section which includes font of bolt and chamber?

  • Southpaw89

    Very nice, I want one.

  • Kivaari

    It looks mouse-trappy, like so many German rifles.

  • RICH

    COULD THIS BE AN AK-HK….. ? ? ?

  • MPWS

    In absence of knowing whether this is a duplicate or original, two items strike me. One is excessive amount of wood left around (obviously hot) barrel; second is that famed German capability of making early plastics (specifically thermosets) is not applied for top of fore-guard. Or even metal stamping for that matter; wood is just not suitable. Section is ok, but it is screwed up by using same paint for all parts.
    On positive note: bringing this as part of curriculum as much as historical review is appreciated.

    • MPWS

      Just to fill in comparison with upper fore-guard on Vz.52 – it has sheet metal backing. I know, it is not war production either, true. Yes, wood has some good properties and appearance, but up to point.

    • mosinman

      Wood actually insulates the hand better than Bakelite does in my experience

  • Best_Guest

    Interesting. This appears to disclose the “inverted” piston (moveable sleeve over fixed piston) that was later patented by Adams Arms.

    I wonder of TFB’s patent guy will have any comment or analysis?

    • I am TFB’s patent guy, but I am not a patent attorney. 🙂

  • Jamie Clemons

    That is not safe to shoot.

    • MG-42

      The cut away or an actual rifle of this design

      • Jamie Clemons

        The cut away LOL. But it would be fun to see them shoot it with a string from a safe distance.
