An M16 cut is fully machined to original M16 specs. It only lacks the hole for the M16 sear. Here is a BCI Defense lower.

Isn’t Shadow Ops Weaponry out of business after screwing people out of $900k?
Or does this list include lowers no longer made / available? |

So you can put it on upside down?  Quote HistoryQuoted:
Quoted: Why is there an extra hole for the trigger guard on the left side? There is a local shop that has their own branded lowers with those same cuts in the trigger pocket for $65 IIRC. I am going to have to go back and check them out, they had no roll mark/obnoxious logo, making them look like the PSA or Spikes' Stealth models. |

Quote HistoryQuoted: Why is there an extra hole for the trigger guard on the left side? There is no logo on either side of the lower, just the required markings ABC-15, Cal Multi and the serial #. I picked this up at a flea market (gun show) 3 weeks ago. So does it fit the criteria the OP was asking about? Im still not clear on that. |

This is an interesting examination. If I understand it correctly, low-shelf and M16-cut are different, with M16 being even lower?
I'll take a look at my Stag Arms from circa 2006(?) if I can find it. --------- That PSA is active on ARFcom right now, they may be able to give insight into if they did a switch at a certain date, or if it was machine shop dependent on who they used to source from before going totally in-house (if I understand their workings correctly now). If PSA is random within same-month / same-era offerings, then I'd love to know what they thought about it all, and why the seeming randomness. --------- At some level, I have to wonder if some forge company was know to make weaker castings in some area or some way, and a common thing to do for lowers from that forge (or from a few forges) was to elave them high-shelf? Or is it a manufacturing choice to reduce time and cost of cutting bits? |

Disregard. I got a hold of SOLGW and they confirmed they are all M16 cut. Odd the pic shows a receiver that isn’t, but who knows. Well I guess I’ll grab one unless I can track down a CM4 in the next couple of days.

Seems there's some confusion on what's what here in the thread. I'll be doing a DIAS video shortly but the video below should help explain/demonstrate/show the difference between low shelf and full auto cut.
