Justin from Roderus has put one of his CNC'd AR-10 blanks on eBay...

cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3635221597&category=36258

I will be watching this with interest...

First day of bidding: 164 hits, no bids (start $199)

Second day of bidding: 291 hits, 2 bids (now $201.50)

You may want to check on parts cost / availability before bidding....  

Going to have MUCH more in it than the whole rifle costs I'd have to say

I think I'll pass on this particular one...I have no EDM capability...And I don't intend to try milling it out...

But it'll be interesting to see what the max bid is...In the inevitable flurry of bidding 30 seconds before the auction ends...

Justin did a good job on these receivers, but I have two CNCd AR-10s by Rick(ARs4EVER).
I would be hard pressed to find a better looking AR-10 receiver out there.
After I finnished them, they function as good as they look.

It is also worth noting this lower is no more than 50% done as opposed to 80% as advertised...

This would be one tough project IMHO.

Gotta agree with ya QB. I think Justin quit just a bit too early on this one.

Even with his provided "solid model electronic file that you can use to get dimensions from", this would be a tough project for anyone without a full blown machine shop to complete.

All that being said, however, it will probably go for a very large price.

More power to him!

All good . . . . Doug

Justin does excellent work but I tried to email him about the grade of aluminum he's using. 6061 will not stand up to the pounding of a rifle. 7075t6 barely costs a few pennies more and machines a thousands times better.
I'm not atacking his work just the material used. I'll all for making your own. I actually don't own any AR15 or 10's [;)]

I'm glad you pointed that out Rick. I hadn't even noticed that these were of 6061. I've got to agree that it's probably not the optimum material for an AR10. I guess Justin must have had some material left-over from the 15's that he was carving out.

I also don't actually own any AR15 or 10's  [;)]

The fire-control/mag release/takedown pin holes are drilled...Top plane is milled...He probably didn't want to get "over" 80%...

Sixth day of bidding: 710 hits, 3 bids ($217.50)

BTW: I received one of those Les Baer $80 (*not* 80%) forged lower AR-15 blanks; the only thing machined is the magwell...And Les Baer put some serious $$$ into getting a custom-ground magwell broach made...The opening is just beautiful...Dead-on spec, too - no fitting required...

...But everything else needs machining...

That's not 80% but more like 40%. He is allowed to either edm the magwell, or finish the buffer tube w/threading.

Also, I'm surprised that Armalite has not alerted Ebay to close down the auction. AR-10 is a legal trademark that Armalite defends agressively.

I recall reading (possibly in Justins thread at Roderus) that some AR-10 lowers are machined to accept M14 mags, rather than the AR-10 mag. Possibly Justin left it unmachined so the buyer could decide (I'm guessing)...

I seem to recall the magazine is canted in the AR-10, either 6 or 4 degrees, rather than vertical like the AR-15...

Seventh day of bidding: 787 hits, 3 bids (still $217.50)

(10 or so of those hits are mine...oops...)

Well I will admit that I looked at this with thoughts of the FN-FAL running though my mind!

Ninth day of bidding: 961 hits, 4 bids (still $217.50)

What, someone bid *under* the last bid??? (How'd that 4th bid get in there???)

I'm guessing that it goes for ~$300...And the hits = ~1000...

I read on one of these sites that the AR-10 uses the same fire-control parts as the AR-15...Trigger, hammer, etc...Don't know if that's true or not, but in the thread at Roderus Justin did say that he was able to modify one of his drill jigs for the AR-10 blanks...So this may not need a whole lot of expensive parts after all...

...Just somebody with a lot of patience...

I wouldnt by that forging.  Buy one from KT for $175.  His is an AR-10 built to take FAL mags.

Well, I was wrong......

It went for $261.56, after 5 bids...The counter didn't show any stats when I looked (5 mins remaining), so no telling how many viewed it...

...Very interesting...  ;)
