    Just won an SP1 upper from GB. (SP1 build)

    I want to replace my Nodak black A1 upper and lower with Colt upper and lowers. Her is my first step. This one also has the elusive(for me lol) rectangle pad port door.

    Edit: If everything does not work out in my favor, I'll just hold on to it for resale when they are all gone.

    I am. I can't help myself! Lol

    I need to find a lower for it now. Maybe somebody will trade me my Nodak A1 upper and lower for a colt lower. Wishful thinking anyways!

    Beautiful! I love me some A1's with triangular handguards!

    I had BRD for awhile, but sold them all off. I'm just concentrating on my one and only A1 now.

    It has arrived. I really need to find a Colt A1 or SP1 lower to go with it now! Anybody have a spare?

    I finally have a rectangle pad port door!

    Forge code: CM = Martin Marietta made the raw forging for Colt

    Anybody know what these proof stamps mean? C in a square and what looks like VP in a triangle.
    Edit: Just found this info on some intense searching. Lol! The C in a square means Colt did all of the final machining and the VP in a triangle means "Verified Proof", Colt's final inspection and testing proof stamp.

    I was amazed at the prices they wanted for just the Colt lower receiver.

    Good luck with your project.
