This is a Bandai 5055738 HG 1/144 R10 Raider Gundam Seed

Celebrating the 10 anniversary of Gundam Seed (and the rerelease of the anime on Blu-ray) Bandai has released their 'remastered' versions of their great HG kits from yeas gone by. Raider Gundam is identical to the initial release (linked below) but now comes in colors matching the Blu-ray anime, marking stickers, and an extra part that lets you attach Raider Gundam to an action base 2 (sold separately).

This is a posable, high-grade or better injection-plastic kit of an item from the Gundam universe.
