I ordered and received 3 POF 416 Lowers one of which I was going to use to build a 9mm wrath sub gun. To my surprise the internal dimensions of the mag well are a slightly different size than a standard AR receiver (Bushmaster, Colt). A Hahn dedicated mag block will not drop in, a colt 2 piece mag (pinned) block will not fit in (if you try and insert the two pieces and a 32rd colt mag) and lastly the receivers will not seat into a standard work bench vise mag well block (all of my other AR variants fit fine). All three of the POF 416 lowers are consistent with the same as explained above. Has anyone else noticed this ? I called POF earlier today and left a message- no response yet. The receivers are beautiful (worst case I will mill/shave some metal off of a colt 2 piece block and use it for my build rather than the Hahn block. BTW- they fit and function perfect with a regular 30rd .223 mag |
| Hahn Precision has a drawing of what a Mil Spec magwell should look like on their website. All of the billet lowers I have seen to date have machined and not broached magwells, lots of big radius cuts with drills and endmills. Technically speaking a forged receiver is 'stronger' than a billet one as long as the overall shape is the same, not that it is much of a difference or a factor. The only reasons to buy billet is for additional features designed into it, if any, and how they look. |

I have a gen1 lower and so far the 20 round new NHMTG mags that i picked up from 44mag.com last year will not fit in the lower at all. I picked up some used Simmons 20rnd mags at a gunshow and they all fit. H&K & D&H 30rnd mags fit fine. I have not tried any Pmags yet. If anyone has tried Pmags, please let me know. |
I would not do it. Also it does not seat well with Bushmaster or Colt uppers (very sloppy). No way I am using these lowers ..real bummer (I’m suck with three) anyone want to trade |
