thanks for all the info, here are a couple pics
This rifle has the bayonet lug, previous owner drilled an extra hole in the stock tube making it a 3 position, flash hider had been changed, had a Colt .170 pin match trigger and hammer installed, non Colt handguards.
got it pretty much back to the way it should be, I guess,
certianly not "Pristine" as it was described, not too bad for $1100.00 though
Got a line on a complete lower of the same kind but still working on it
