Olympic Arms AR-15 rifle
This was made during the rifle ban when you could not have all of the scary features such as a bayonet lug, flash hider and foregrip
This one was made using a fore grip and not using the flash hider and bayonet lug so it must be much safer than a modern AR
Caliber is 5.56 Nato or .223 Remington
Scope mounted on top of handguard.
