Good. Bore is dirty with some firing residues that should clean to Very Bright and sharp rifling throughout. Metal finish shows oxidation forming on the edges of the exterior gas port, some thinning to barrel, and light scratches on the receiver. Upper and lower handguard display some stress cracking, while the remaining synthetic parts display light abrasions. Mechanically functional when cycled by hand. Finish thinning on magazine. Magazine release button occasionally sticks.
