The M1 Astray is the mass-produced version of the Astray line of mobile suits for the Gundam Seed.
With that wait, the kit employs some of the more modern engineering for it’s build.
For a grunt, they always gone for a more simplified look.
Yes, the shield is exactly the same as it’s HG Astray Red/Gold/Blue/Green Frame 1/144 kits, but the similarities ends there.
The backpack is totally integrated with the main torso, but, the lower thrusters are movable like the Strike’s Aile backpack system.
The head shares very little from it’s predecessor, features like the head vulcans, side air-intakes and V-fin remains.
The lower thrusters are attached by using a ball-joints so it can move freely, and the gray areas are done by seals/stickers (which may peel off).
Unlike the old Astray (whichever colours) kits, the abdomen has a ball joint, also the side skirt armours are movable.
