Living in a ban state I picked up a preban PWA lower with a new stag upper and an EOTech for a little more than what you payed.
Apples and Oranges, yours is a parts gun, mine is 100% Colt
I'm thinking you paid around 2k, that puts you paying around 1,700
for just the rifle.

After seeing that I think I'll list it on Broker after the year end.
Give someone the chance to pick up a like new (20rds down the pipe)
100% Colt for around 1,300. That will give me enough to pick up a 6920 for replacement.

Are you positive that it is in fact pre-ban?
Yes, I picked it up new in the fall of 94' just before the AWB
