SIG 80% p228 frame

[lawnrevenge]

I'll probably get some "nice" responses about this, but here goes.
I am getting a micro mill soon and want to start some easy projects for it. This means I'll be ordering a "60%" 1911 frame and have fun doing all the machining joy that is involved (not just a add rails frame).

I also saw that there are Sig p228 frames mentioned, yet I can't find any to order. Does anyone know where i can get one? Or any other non-1911 frame blanks. Once I get the hand of machining I will just make some frames from blocks of metal. But for now I just want to learn on something easier. My other project will eventually be an AR lower with a built in magazine, something that hinges down and can be loaded with stripper clips but is "fixed" to eliminate all the AW BS.

There is ongoing controversy involving "80%" frames.

THERE IS NO STANDARD FOR COMPLETION OR QUANTIFIED BOUNDARY ON WHEN A HUNK OF METAL HAS ENOUGH WORK DONE TO IT TO BECOME A FIREARM.

PEOPLE ARE GETTING IN TROUBLE FOR "80%" crap.

Your standard of 60% may be 95% to the BATF. There is no specified standard of time or complexity required. Starting from a blank rectangular forging is really the only safe way.

Anyone who buys a so-called "60%" or "80%" frame is at legal risk for illegal firearm acquisition not going thru an FFL.

If you really really really want to do this the 60% proto-receiver should be run thru an FFL and be 4473'd/DROSed for your protection.

I'd avoid the whole partial thing all together if I lived in a free state where I could just go buy a new frame at my local FFL shop. Apparently a "drop test" done on a frame would be inconclusive. The reason I want to start with a cast block that resembles a frame is to make my first attempt at making something.

If the seller has an ATF approval letter for their specific frame saying it's not a firearm then I think it will be ok to buy. No letter, no purchase.

Of course, with a set of plans and a store bought version I can probably just bust one out anyway. The AR lower receiver should be pretty easy. I want to make it so that a standard magazine can't be inserted. Basically like an SKS magazine with a release and hinge, with a built in loading mechanism and retention like a standard magazine. I've been playing with some idea in CAD but haven't set it in stone yet.

When I do get something done worth showing I'll be happy to post.

Not sure what the space requirements for your shop are, but I would look into a bigger machine then the Micro Mill. The Micro's usually only have 8" X travel and 4" Y. You will end up repositioning your project and re-zeroing frequently. If you just want to make some chips and learn to machine, then it's tough to beat the cheap price (Turn it into a CNC Mill after you move to a bigger machine)

Yeah, I don't want to spend too much to begin with. I may decide that I don't like it...or that I just suck at it. I look at it like most of my tools. I expect it to pay for it's self before i upgrade. Works with computers, and other power tools. I can bang out some stuff for buddies (non-firearms stuff) to eventually cover the cost.

Ok, now that I've been "researching" this some more...
There is no way I'll be buying an 80%, 60%, 40% or whatever receiver.
It seems that the BATFE is in the process of royally screwing a few folks over this now. Judging buy what I read about their dealing etc. I don't want to be involved with that...
I guess my 0% frame will be the way to go. You know the frame that looks like a big block of steel or aluminum.

There is actually a very good posting floating around on the web about building a SIG from 0%. As has been said in other posting here - 0% or 100% - both are legal. In between is a grey area and if you're building it because you want to build it - start from scratch. It's far more impressive.

That's a great site. The guy is doing it all with a CNC mill...I must resist the temptation to squander next year's tuition!!!

The Machine is just a small investment, the tooling is what will break the bank. My wife hates when the Enco or Rutland catalogs are mailed
