based on the pictures youv shown.
bolt looks correct, extractor is not.{03}
safety is aftermarket, and belongs in the trash..dangerous.
cocking rod, incorrect. [03]
follower and floor plate, incorrect. [03]
id bet the trigger guard is also an 03 not an A3.
scope as you know is not GI, nor the rings.
cant see the muzzle so i dont know if its cut down.
that rifle really needs a restoration, and done correctly.
a great start to a nice rifle.
