I have started this kit at a recent club session and worked on it while my VBL weathering was drying.
The build is straightforward with excellent fit. You only have to enlarge some positioning holes here and there but nothing more. The steel PE parts are a bit stiff. The gun is molded in three parts: the base including the fume extractor, the barrel main part and the muzzle. The fit is perfect and you just have to remove a tiny mold line.
The tracks are individual link type with the link, the guide teeth, the end connectors and the rubber pads. Academy tell you to assemble 78 links per tracks while 75 are enough. The tracks are “mobile”.
The side skirts are not glued yet pending the painting of the running gear.
