Man Fires Tactical Rifle at Indoor Range

Replace the man with the elderly man from the reference images. Keep his exact identity: thick white handlebar mustache, bushy white eyebrows, black beret, white ribbed tank top, dog tag necklace, brown corduroy trousers, faded forearm tattoo, very muscular arms. Green ear protection earmuffs worn over the beret. No glasses, no black shirt, no jeans. Keep the exact same rifle from the original video, unchanged: tan / flat dark earth carbine with a long slotted handguard, holographic sight with a flip-to-side magnifier on top, vertical foregrip, tan magazine, tan sling and muzzle device. Same size, same color, same parts, same position in his hands in every frame. Do not redesign or replace the rifle. Keep the original motion, timing and handheld camera movement exactly: he holds the tan magazine between his teeth under his mustache, reloads the rifle, then aims and fires downrange. Indoor shooting range, concrete floor with spent brass casings, wooden ceiling beams, paper targets in the background. Plain walls with no text, no logos, no signs. Photorealistic. His face stays calm and serious the whole time, completely unbothered.
