NSN 5220-00-233-8937
https://www.wbparts.com/rfq/5220-00-233-8937.html They're not common at all. Looks like the DLA provided 1 in 2019 and 2 in 2020 (to the entire military). They do seem to only be produced by Rock Island Arsenal. No other contractors are listed. Some dimensions are listed (2.545 in. lg; 0.945 in. W) but Idk where to find the specs. Edit: That Form 3023 in the background isn't bad...  |

Well there's a million-dollar idea for someone. Another AR thing that nobody needs, but everybody will buy.

My goal is to have these made (along with 0% lowers) that’s why I was asking for dimensions

Quote HistoryQuoted: It's still not needed, if you're capable of milling it correctly in the first place. I doubt any of the big CNC shops have them. Certain companies who produce their lowers in-house might use them (for QA). I’d imagine this would be useful for smaller/custom shops not the big mass production companies. |

Just depends on what their QA program is like.
Many places do not have much of one. Most small shops have their receivers produced by a larger manufacturer (with a marking variance). |

Quote HistoryQuoted: My goal is to have these made (along with 0% lowers) that’s why I was asking for dimensions That is not the gauge you want for manufacture. That is a re-build serviceability gage. It is used to see if a lower will still accept a magazine. If you are going for 0% building and want a gage for the magazine well, you want P/N 8443881 - Gage, Plug, Special (Magazine Opening), and 8443595 - Gage, Location (Magazine Catch). You might also want the other 80-some-odd gages for the M16 lower receiver. |
