I saw this at the USMC museum in San Diego. I thought it was interesting as the sear hole had been cut out.  |

Now I just have a bag of selectors hanging out in the armory.

Anything wrong with having a square cut like that? the upper would hold it in place |
Let us never forget, government has no resources of its own. Government can only give to us what it has previously taken from us.

Anything wrong with having a square cut like that? the upper would hold it in place That receiver is a MG no matter what (per US federal law) unless it undergoes DEMIL. The current US gov DEMIL standard is to torch cut in 3 sections, with the center section destroyed (or mutilated to the point of scrap). |

I was speaking hypothetically about the legality of having a square cut like that in a non NFA AR.

Originally Posted By Banditman: I was speaking hypothetically about the legality of having a square cut like that in a non NFA AR. I know it won't turn a MG (M16) receiver into a Title I (GCA) firearm. Scroll halfway down the page on this site https://www.thefirearmblog.com/blog/2020/06/29/m-a-c-s-rifles-snes-laser-m16s/ Clearly they didn't want any troops to re-install automatic sears in those receivers. |

Unfortunately ATF just ignores it and continues with their bullshit mantra of “once a machinegun, always a machinegun”. It would be very easy to convert back. A couple of square bushings with a small lip on one side, sear and pin with c clip cuts on each end that is long enough to protrude just enough to allow c clips to be installed on each side. Or a pin with head on one side and clip grove on other. The upper would keep it in place. No machining to receiver needed. |

Lots of semi receivers are M16 spec in the FCG pocket. An auto sear pin hole jig and a drill and you’re done. Or in others, a Swift Link can be 3D printed or made from a coat hanger. I think restoring FA function in a lower that has been modified like the one in question would be harder than the above scenarios. |
