What's up with that? THAT is a M-16 receiver, PERIOD! Looks more like a single-shot receiver to me. (I'm not ordering one 'til NOLO wins, though.) The older style 80% w/ a solid magwell sure would make things easier if one had an ARES belt fed upper or a .50" BMG upper. Tap the buffer tube boss and you're in business. |

I love the fact you can toss yours in an oven, and 30 minutes later you've just got a pile of parts again, no gun.

Russ4777, do you or anyone else for that matter have the details on the parts needing modifications? I want to tig one, it should come out pretty clean, I'd like the milling to be clean too.
I've seen mention of it, but haven't seen the exact specs anywhere yet. This is as good of a place as any. TIA |

You used a proper tap. The mods I made to the side plates are clearly depicted in the photos above and described by BackBencher. I don't have the dimensions. They are self-evident as you tack weld the thing together and start trial fitting the lower parts. I did add some extra small plates where the rear takedown lug enters the lower. The opening was WAY too wide and yes I had to add some additional material to accommodate the safety detent hole. I tapped the receiver extension boss all the way through. A standard tube fits perfectly. This picture shows the interior mods/added pieces. I just noticed in this picture that I had to machine a small amount from the floor of the rear portion of the fire control pocket to give the trigger more reset travel. |

Might remove KT Ordnance, they're no longer making 80%s. Shame, as @ one time they did 1911s, P226/8s, Ruger Mk 1s, DPMS style .308"s & ARs.

On my screen it looks like a dark shade of green

Yeah, it is the camera or flash. The right side and left side pictures the color looks completely different. One side looks bronze and very shiny like the previous pics, the other side you can tell it is green. Matching some of these colors can be very difficult as there is no universally accepted hard and fast standards as to what OD or FDE or any of those colors are. Different part makers produce different shades even when they use the same names and some things can vary from lot to lot or even part to part.

|

They are now labeled as cerakoted, they weren't when I bought mine. So I imagine my lower is Cerakoted FDE.

In machining out an "80% Lower" the rear lug is one of the more critical fitting dimensions. why risk it when you can buy one already cut. I couldn't agree more. That is the one thing I look for when purchasing a lower. I messed up a couple of lowers from TR-Enabling when I first started the 80% game. I machined out the rear lug area too wide and any side to side movement locked up the BCG rearward travel. I ended up filling them back in with aluminum epoxy and re-machining them out. They look like shit but it fixed the side to side movement. I recently purchased an 80% lower from Fedarm and the rear lug area was out of spec and did not allow the upper to close on the lower at all. The area that would have been left between the trigger pocket and rear lug was hitting the rear lug of the upper. I had to disassemble the lower and machine out that area. Not a big deal but frustrating. Mora of the story, make sure the lower is in spec. |

Found these a year ago or so. Bolt catch pin is a threaded hex head so no dealing with that damn catch pin or having to tape up the lower to install, takes two seconds with this lower.

I pre-ordered months ago and they are about 2mo past the originally given release date. I've always wanted an AK mag pattern AR. I was ex Utes for the CMMG mutant till I found out it was an intermediate between AR-15 and AR-10. Then I was excited about the PSA KS-47, however I refuse to be an early adopter of anything they make after seeing how the PA-10 and PSA AK-47 release went. |

The Palmetto KS-47 is having cycling issues with any pressure on the magazine (but seems to cycle fine with no pressure on the mag). I'm curious if the BRS-47 has this issue sorted, or if it may have similar issues. |

I still haven't finished my BRS-47 due to my sandblast cabinet.
I built a filter that fits inside the cabinet, and changed out the light fixture. Once I get the lights attached, then I can blast the receiver, cerakote it, and finish it up. G. |
