1911 80% lower frame

tn_sarcoframes (5)

With all the talk about 80% AR lowers, did you know that there are 80% 1911 lowers?Ares Armor sells them, but they are not the only game in town.

Tactical Machining makes a railed 1911 frame. Only a $10 difference between 80% and 100%. The difference is the slide rails, hammer and sear pin holes, as well as the barrel seat still need to be machined to complete the frame.

 

Here is the 80% 1911 frame

    any good sites on how to build these? i know there is tons on ARs but i just got done doing a 80% one of those and i now want the challenge of a handgun!

  • Ken

    I wonder how many of these will actually be made into well functioning 1911′s. It’s very critical to get the rails and pin holes precise.

    • Dan

      Probably most will since you have to have a milling machine to do the rails anyway. Anyone who owns that kind of equipment is likely going to be fairly competent.

        but do you really? I’m envisioning a system involving clamps, a dremel with a cut off wheel and a slice of plywood… :D

        • BryanS

          if you did it with a stationary cutoff wheel, a sliding base, and took small passes, that might just work, somewhat like a very cruse horizontal mill. Or similar with a file, like a basic shaper.

        I’ve got a pretty nice milling machine. But I’m not very competent. I’ll probably start with some plastic lower kits to gain experience, then work my way up to frame rails.

      • Mart

        If they can do it in Khyber Pass using simple workstations, you can do it at home without a mill, especially since all the hard work’s already done.

    Someone get us some 80% forgings!! Dlask used to offer 60% forged 1911 frames a few years back but they required skill that I did not have lol.

  • Scott Tuttle

    too bad you have to do those rails. a few holes needing drilled I could handle.

  • gunslinger

    does the 100% needs to be transferred via FFL?

    • BryanS

      A 100 would be a firearm in the eyes of the feds, so yes.

      • gunslinger

        wasn’t sure what parts the fed’s wanted to regulate. 100% ar uppers are just hunks of metal ;-)

        • Phil Hsueh

          That’s true because it’s the lower that the Feds consider to be a firearm. An 80% AR lower is a paperweight, a 100% AR lower is a firearm.

          • BryanS

            Generally the part that holds the fire control group.

            Fed have different nomenclature for “Firearm”/ “Frame” and “receiver”

          • Phil Hsueh

            While that may be true the important thing to consider/know is that the lower receiver is the part that the Feds think of as the gun since it’s the part that gets DROSd whether it’s stripped or complete with parts already installed.

      • 1911a145acp

        Interestingly, The feds do NOT consider a Frame or Receiver a “Firearm”.
        It is however the serial numbered regulated part. It would require an FFL transfer paperwork.
