(I got it/understood.)

A person in a grey long-sleeved shirt and dark shoes is disassembling a black AK-style rifle on a blue mat laid on grass. The person uses both hands to remove the magazine, then the bolt carrier group, and finally the handguard, placing the parts on the mat. The rifle is reassembled in reverse order. The scene is outdoors in bright sunlight, with shadows cast on the mat.
