Hi,
I came in to possesion of a grey M16A2 LK marked upper.
From what I have seen this was made by LAR manufacturing and they started making parts for rock island in the sixties.
Does anyone know anything about what years they made A2 uppers so I can have an idea of when this may have been made?
Also if a grey lower and triangle cap handguards would be the appropriate build for this?
Thanks
