    A great conversion kit, well cast and really enjoyed installing the sponsons onto a Leman Russ. At first it felt quite daunting, but I followed the video tutorial which made the whole process really simple! Definitely recommend this kit. Will be ordering again in the future!

    Thank you!

    Great kit, very professionally done. YouTube tutorial covers everything you need to know. Takes some skill overall but looked great finished. It looks very natural when completed. Great detail in rivets. First assembly a little slow as I was learning but 2nd and 3rd assembly were very fast and easy. I will recommend this for sure.

    Don’t be like me and install them into an already made Russ, it works but it’s harder. Great kit and the look is awesome

    Absolutly love them, got 6 sets for my krieg mars leman russes and sadly only have one finished the backlog of 130 infantry definitely come first. But the kit was easy to install and gives my krieg tank a slimmmer more unique profile. Already used it in a local tourny and everyone askes me how i did it. Thank you they are easy to assemble and very appealing to the eye.

    Purchased 3 kits for my Catachan Jungle Fighters. Kit installed without a hitch and they looks great. If that wasn’t enough they have the added bonus that I can easily get more tanks in my transport cases (vs. those that have the GW sponsons on them). Get these and put something unique on your gaming table.

    This kit is rad. It requires a bit of advanced skill to convert but totally worth the effort.

  11. Steve (verified owner)

    Great kit, makes my Leman Russ’s Look so much sleeker. Easy to fit, but made even easier by instructional videos on YouTube! I will by buying these for all my tanks.

    I was bought one of the kits as a gift. Really well packaged and a great quality cast.

    As I’m brand new to the hobby I have never done any conversion work before however I followed the YouTube tutorial which made it really simple!

    Would definitely recommend and use again in the future, thanks Phil!

    A lovely kit, well thought out and nicely made. Even though I acquired one of the ‘seconds there were no issues with these and even added a bit of character to the vehicles.
    Definitely recommend them.
