Thanks PhillipM and LtDave for your interest. Being in a hurry to take pics I failed to take one of the muzzle end of the barrel. This came from Colt without the bayonet lug. I traded a Remington Wingmaster 12 gauge pump shotgun even for this AR15 back in 91 at a gunshow in Ohio. I never thought much about it until recently when an old friend asked about the Remington as we went to a lot of turkey shoots back in the day and the old Remington did quite well. It turned out to be one of the best trades that I ever made. Kinda having second thoughts about selling it now. I'd still like to know what it may be worth since everyone seems to make them now. Be safe and God bless. Rich.
