Very good stuff for my Ultramarines!!

I ordered several items from 18th Scale Armory and all went very well.
The mkIII is very well detailed and easy to paint, scale is perfect for Joytoy marines even gen.1 with smaller hands!
To be clear, I’ve already ordered another batch of weapons for my collection :)

Perfect cinder blocks for my diorama

Finely crafted and actually 1:18 scale. Just what I needed for the corner of my garage diorama. A little weathering and shadow painting and they are perfect. I will by from this seller again and if I could give a higher than 5 stars I would. Thank you for a top quality product.

Very impressed

The Jump pack model is designed perfectly and doesn't feel too bulky or combersome on the figure.
