This was a bit of an impulse purchase as I already had an Achilles but this Ready to Roll one was cheap on the B&B at Gauntlet. The existing model is the Armourfast one and I've never been completely happy with it.
I was quite pleased to find it was actually smaller than the Armourfast one so it will fit in better with my mainly 1/76 models. It was fairly quick to assemble and paint.
Here a picture of the original models one as a straight M10 the interior detail had to be added.
