I have a new takeoff "T" rail marked keyhole forge A-3 flat top upper for sale. I got this as a complete upper unit from Tim Mears in Alaska, it was sold as an CMMG upper to me. I needed some parts for an Israeli Carbine build, so the upper is extra. E-mail Starkravingmags@aol.com if interested. I take M.O. or check, no paypal.
Selling for $126 shipped USPS.
Thanks for looking.
