As some of you know, @backbencher is getting married and had a giveaway as part of his celebration. backbencher's thread
I chose to participate and I've won the chance to build a Flat Spot Lower. I have a year to complete the build, before it would move on the the runner up @sixtigers. I'm probably a week away from starting the build, but I did receive the kit, and after looking at it, my first reaction was what the hell have I gotten myself into... See pic below. Anyway, I'm starting my build thread and I'll update with pictures as I go along. Thanks again, backbencher Also, I encourage any ideas of what kind of rifle you guys want me to turn it into. Something like @raider14's post apocalyptic build or something more standard... Help me decide. Updates below There's more pics down the page but heres the TL;DR 5/5 5/6 Test Fired on a known good upper. IT WORKS! Video of test fire on lower 5/8 Almost there 5/11 5/15 Raiders sight came in. 5/16 5/24 5/25 5/26 |

I'd vote for something post apocalyptic (obvious bias ) or something "retro-futuristic"/alternative history ish. Like wood furniture and if you skim through my big build thread, there was an idea of skinning a trimmed/modded regular upper in square tubing (think AR-180 look externally but all AR-15 internally)
As for help: It's a lot easier if you just opt out of stuff that requires drilling like the safety and bolt catch. Best thing I can recommend is to NOT let it get hot or it will warp like crazy. If you have access to a tig it helps a lot. If mig you may want to grind after every weld for clearance. A vice, vice grips, clamps, bolts, and anything else you can use to keep it rock solid is your friend I'd also grind out the slot for the magazine mag catch lip thing in the magwell beforehand. You'll also need to modify a standard mag catch by building up the part that actually catches onto the mag and maybe some other fitment stuff A Dremel along with opting for some of the "new" legit grinding disks they make will help a lot. They are very high quality and tough while allowing for actual precision grinding that'd usually be left to a file. That being said the disks + mounting bit thing will set you back like $25 Check fitment at every possible moment, if you have a stripped lower or at least an upper to bolt it to it will help Don't worry about the bagillion sharp edges you'll have until you get done If you have any issues feel free to message me |

I've always considered tig welding one of these together and powder coating it when done.

We talked about that in Raider's thread. It's a 1" tube. He decided against it. I'll try to find you some dims off Weaponeer tomorrow.

Holy smokes, dude! I saw the buffer tube boss and thought, uh oh, hope he doesn't misalign it. Next pic was snugged up w/ an upper. Wow!

Did you cut a slot in the mag well, or are you going to build up a standard steel magcatch? View Quote I'm still unclear whether that's a do one or the other. But I'm prepared for either now. But being a post apocalyptic build, a little ugly is good! |
|
That's the upper I'm going to use. It's a blemish because the forward assist was drilled wrong.
I plan to grind the thing down and make it look less "cast" and more "created" but it's hard not to utilize the flat top for optics.... so it can be practical and neat. |

Many, many thanks, sublimeshooter. I have given many of these away to friends who weld - you're the first who has gotten after it.
I would like to point out to those following this thread, that even if you don't weld, it costs less than $40 to birth a new gun into the world. A gun without a serial number. This makes liberals cry. Isn't it worth $40 to make liberals cry? Give an 80% lower today. |

Still have to decide how I want to tackle the buffer tube. To all of those intimidated.... it looks like a ton of random parts. To be truthful, it is... however after you get the trigger assembly together it just kinda comes together and makes sense. edit: @sixtigers I'd be happy to pay it forward to you, since your "runner up" wont pan out . I am excited to see your methods and build. Pm me and I can either paypal you the kit cost or get your info and send you a kit. And before you say it, it's not about the money.. It's about the idea! |

Tagging this for now. Eventually I'd love to do one of these as a DIY project.

@sublimeshooter, that's a very cool offer, but I don't know if my skills are up to it. I'm not a welder by trade, and I'm afraid I really don't know too much about it. Let me watch your build unfold and admire its post-apocalyptic glory, and you hold on to your generous offer! I'm probably going to attempt one of these flats, but I'm afraid I'd feel obligated to display my metal butchery in progress were you to gift me one. This way I can hide my shame and crimes against the welding gods that are sure to surface...!

Parts are in and it seems to function properly. My only real hiccup today was the trigger plate, I had to mill it down for the trigger to function. weight reduction
Also, the mag release does need built up along with the plate ground down. It is not a one or the other kinda thing. |

That's been noted in other builds - it's not clear if everyone has that problem or not. Love the mag fence. I've tried bolting together a cracked $20 Sabre Defense (Cav Arms Mk2) from Trinity Ordnance (sold as cracked, hence the price), and found I'd threaded the inside of the rear take down lug in my upper. Obviously you're not worried about this upper, but keep that in mind down the road. I might suggest wing nuts for the rear take down pin - or cotter pins.

View Quote Yeah, I don't care about this upper at all for the $5 I have in it. The bolts shoulder goes clear through the lower, so it cant thread anything but that's a good thing to be mindful on. I had the same idea you just suggested, I just haven't decided on which. I'm leaning towards wing nuts. |

Dude, you need to force a patina on that. IMO it'll look awesome. Personally I use a mixture of lemon juice, fresh coffee grounds, white, and cider vinegar, before letting blades sit surrounded by it for ~45 minutes to an hour. Here's a Mora that I did this soak to.

Basically, under high heat the carbon migrates from the bone to the steel it's rubbing against - and some of the calcium comes over as well, making the pretty colors. You don't have to buy Brownell's kit - you can use any old bones in your furnace. It hardens the surface of the steel, leaving the inside soft. |

Mines sitting on my bench, mocking me with taunts of inadequacy. View Quote Now, if you're gonna save yourself a cool couple of thousand on a Turnbull color-case hardened receiver w/ a $37 kit, you're probably gonna need some skills. To replicate what Raider14's doing? You need to be able to tack some parts together & have a redneck engineering spirit. If you're gonna build yourself a Tok lower that takes PPSh41 or Suomi drums, you've got to be damn good w/ a Dremel, or have a proper mill. I almost got one of these together w/ super glue - tack welding won't be pretty but it should work. |

It's called color case hardening, from prior to the high carbon steel age - which is handy, as your lower is of mild steel. www.brownells .com/gunsmith-tools-supplies/metal-prep-coloring/color-case-hardening/color-case-hardening-kit-prod1026.aspx (broken link b/c of Avantlink) If done right, as Turnbull does it, it produces beautiful colored patterns on the thin hardened surface of the steel - as Colt originally did on their revolvers in the 1800's.

I'm meeting AFCarbon15 tomorrow to thread my lower. (This site has great people, and its amazing how close some are) So I'm foing.... and if it turns out to be an Arock ordeal, It was nice knowing you all. But make him finish the build and tell him I expect he better have got top dollar for my kidneys!

Ah, but fancy guns have it today b/c it brings back memories of expensive rare guns of yesteryear. But the remaining guns of yesteryear are expensive b/c they are rare, and they are rare b/c they are the guns of yesteryear. They were made from mild steel, and to get that steel up to the point where it could hold the gun together, it was color case-hardened b/c it was low carbon steel, and that's what works, and it can be done by any damn fool w/ a charcoal fire and some bones.
So post-apocalypse, many guns will be color-case hardened, due to the high availability of bones - and a lack of high carbon steel. |

Your counter argument is valid.
How about I see if it actually shoots first before I try. One new experience at a time. 100% sure now, you are a bad influence. |

Dude, idea. Wrap the pipe in cut open inner tube. it would also protect your knuckles against the back of the trigger guard. Finish the bottom off with a pipe cap.
That or rough it up a bit (just a few passes with a file) then paracord wrap it. |
