styrene, this was a very easy kit to put together. I only had 3 problems with the build. (one was my fault) The problem that was my fault was I misenterpereted the instructions, and assembeled the part that mounts the gun to the chasis too soon (if I did it right, the gun could traverse). The two problems I had with the kit are the sheild, which went on a little tight with the lower sheild, and the bit (I can't recall the name) that sheilds the gunner from the breech, when installed, doesnt let the gunner fit properly (In the pictures with the figures installed, you can see it is quite badly bent out of place. If anyone else here has built this kit and knows how to correct this, please tell me.
