I picked these up a while back for a project and thought they were strange, lower handguard has no heat shield (or provision to mount one) and no holes, the upper has a heat shield and 14 holes. They are alos made to fit a round handguard cap only and are top and bottom and cannot be switched.
There is a thread about these showing pictures and verification that they came from Colt's tool room here www.ar15.com/forums/topic.html?b=3&f=12&t=247112
I have no idea what they are worth but the certainly are not common and I would assume an important part of the M16's development, I would like to trade for anything AR related, tell me what you have and we can haggle, good old cash will do also
