·I have an upper assembly with no markings on it. The only marking is "4BI2" on the front sight bar right above the barrel.
Any suggestion and there is no barrle markings. How can I tell if it is chrome lined or not?
It shoots ok, 1-1.5 MOA at 100 yards so I'm hapy with rifle but would like more information.
