There is a guy on gunbroker selling 80% lowers for $80.

I like these because they already have the buffer tube reamed and threaded. These will need the FCG area milled out, trigger pin holes and safety selector detent hole drilled.

http://www.gunbroker.com/Auction/ViewItem.asp?Item=141651118

My question is if I finish one of these how do I go about building a pistol out of it? What is the process?

The CNC jig makes quick work of these.

Yes Greg-Dawg, no stock. All the rest of you guys, thanks. I may be heading to the Reno show in November to see what's there.

www.ktordnance.com are the folks who started all this I believe. They sell everything you need to finish it.

Tactical machining lowers are about $380 shipped for 5 of them. Just make sure you have a tap for the buffer tube if your want your receiver extension to screw in all the way.

80% refers to an unfishished lower, which at 80% completed or less is not a firearm. Once you start to complete the lower it turns into a firearm under the law. You then own it, without going through a FFL. You can sell it only if its properly marked and you dont make it to sell it.

Actually it can never enter commerce unless you have a firearm manufactures license. My lower is one of these and the best part is it can be hand fitted to the upper of your choice for zero slop, added to accuracy. They finish great and like diesel said no FFL, so it doesnt "exist".:D

Here is the website I got mine from, they got everything. Including raw 1911 frames, LPK's, 80% lowers, AK reciever flats...etc.:D

If later one, you want to sell/transfer it, you can, but it must be marked with your name, city, state, & serial number.

Is this something that is legal to take to the range? If stopped or seen by a LEO? After being finished and turned into a rifle?

As long as it is in a CA-legal non-AW configuration, it is legal. However, it it does not have a serial number (not required for homebuilders), an LEO may think that the serial number has been removed, which is a crime.

Yes. This is correct. I would add that the code stating how a firearm must be marked is very clear. they can bust you for using improper font and depth of lettering. You can't just scratch "Joe's zombie killer 007" with a knife and call it a day.

I saw some 80% at the last show in Del Mar. They do take some time to make but when you are all done you can tell people you made it.

Good luck

Wait what? Isn't the whole point of the Tactical Machine lowers that the buffer tower is already tapped so you don't have to buy that huge, expensive tap in the first place? Better to just check that your receiver extension fits properly before doing any drilling on the lower and send it back if you can't properly install the receiver extension.

It screws in about half way. On all 5 80% lowers I got, it is not tapped all the way. It needed about 2-3 more threads so the extension could be screwed in all the way.

Thanks for the info. I guess I won't be ordering any of those.

the play between upper and lower doesnt affect accuracy.

That it did. It's one of those "damn, why didn't I think of that" inventions. Costs nothing to make and promises you the world.

Mine are all fine, check your tube.

Their website refers to having to finish tapping that all of the way. Their site says they are only tapped half way.

After examining the lowers again, I think that once the FC pocket is milled out, the buffer tube will screw in.

is there any age requirements for these like buying a stripped receiver?

^^^ None at all, these aren't considered firearms. They are just blocks of metal.

Exactly. They're paperweights. Does anybody know if there are any age restrictions on actually making them into a firearm?

So if I were to complete this into a 100% lower and I make this into a rifle with a California Legal OLL configuration, will everything be all good? Can I engrave anything I want on it before I get it annoed? Does this mean I never have to get this thing D'ROSed?

I'm pretty sure that is true. Its one of the easier ways to build a pistol AR in CA. I have thought about building one. It would be pretty easy with mill access.

Even easier with the drilling and milling jigs from cncguns.com. The Tactical Machining lowers only need about 2 holes drilled.

so is the reciever extension the same as the buffer tube?

Do you guys know where the regulation that governs the situation after I decide to complete the receiver on my own and then built a California compliant AR? I would like to have a copy just in case I get stopped by a LEO. So as long as it is in a California compliant configuration, then everything is all gravy? What would I have to do with this to make an AR pistol that is California compliant?

To make money from anal retentive morons. Hell, my 50BMG AR upper isn't tight but, it shoots well enough for me to place in 1000 yard matches against the big boys with VERY expensive custom rifles. But, if using one makes you feel better, you'll shoot better. So, in that sense, they should help some:rolleyes:.

i agree... i work in a machine shop and was looking into cncing my own lower but from what ive read and interpeted its not worth the headache... might be for some but i just spent the 130 bucks and was on my way...

What exactly do you want? The law tells us what we can't do, not what we can do. There is presently no law against building your own firearm as long as they comply with all state and federal laws. What if you get stopped by a cop? You show them the same documentation you'd show any cop regarding an AR15 that it isn't on the ban list and show how it complies with all state and federal laws just like your OLL made by whomever makes OLLs.
