0% AR lowers

Hunk of aluminum, exactly. These should be free from restrictions on cross border purchase and transport, yes? I think I'll check carefully, but that's the impression I had before. Questar used to offer a 10 pack from Spikes, but doesn't seem to anymore.
 
I have some AR15 0% lowers foresale $100 :p

i tried dlask for one a while ago but no luck. he ws getting harrassed by the powers that be and there was apparently a ruling coming or has already happened i dunno.... i forgot to keep tabs on the subject.

i wouldn't mind an 80% ar and a 80% 1911
would be fun projects that's for sure.
 
I'd love an 80% 1911.

There are a few companies down south selling 80% AR blocks and they usually go for around $80.

Would be great fun to be able to build your own up here.

That's nice! I see you've done a little work to it already. I would caution you against parting with that, you might want it later(consider Big Bad Jack). What I am looking for is raw forgings (I knew you knew). Dlask has 80% lowers for $220, and that might in the end be a good way to go, but I can't get my head around that yet seeing as I can get finished lowers from multiple sources for less than that. I'd end up spending more for the one obvious benefit, but not being a machinist, I can envision screwing up at least one operation. I was looking for several raw forgings (0% lowers) for maybe $35 a piece.

While not considered to be a firearm I do believe that the US treats them as such when it comes to exports so the proper paperwork and permits still apply AFAIK. I've been wrong lots of times before though.
 
I asked Dlask for the 80% lower, and as M14Doctor said, I got the exact answer, no longer available. You can machine it out of billet of T6 aluminum(available from Metal Mart) or as one guy did, HDPE. I was planning on machining a test lower out of UHMPE to see if it I could get correct dimensioning and see which was the best process in machining a lower before machining aluminum, that way if I screw up, it wont cost so much. I was even planning to do the hard anodizing and dying myself. I have igs solidpart models(using SolidWorks 2010) for both Ar lower and 1911 frame which I used Surfcam Velocity to program. Very easy if you have the software!! Its all set...just need cnc machine time but work production never seems to halt! Just a side project for now..but if you have the right software and machinery, could be interesting.
 
was just on there website and they still have the 80%ar receivers listed for 220.00 but i dont see the 80%dar 22 receivers anymore
 
If you are going to do an ar, it's actually easier to go from a block than one of their forgings. You can hold it in a vice, machine one side complete including holes. You then use the hole for locating for fixturing. We usually do a female profile (using the cnc of course) to the exact dimensions of the lower in soft jaws on a vice to do the other side. Stand it up using the holes to locate it on a plate, and do the internals, including roughing out the magwell. Stand it on its end, again using the holes to mount it on a plate to do the buffer hole. Take it over to the edm, and burn the magwell, and it's done. Register it and send it off to anodise. You usually need about 3 to cover the minimum charge for anodiseing ( our anodiser charges a minimum of $120) and that is for mil spec hard anodising with certificate. These are of my ar 10

Out of curiosity, where did you find plans for the AR-10 lower? I assume it won't work with other .308 ARs and is specific to the Armalite version, right?
 
One of the guys at work got it on line. It is an armalite lower. If I was to do it again, I would do a .308 ar, simply because armalite parts are difficult to get up here. Armalite barrels are for leo only because they are stamped .762 and if you use a dpms barrel you must use a dpms bolt carrier group also. The mags are also harder to get.
 
There are only so many other AR makes in .308 though. Most common would probably be the DPMS Panther/Remington R-25. I wonder if anyone brought in the RRA LAR-8 via Questar? The KAC is plain expensive, and the PWS or LMT guns are still fairly pricey.
