Here is what I proposes the Team of CNC Guns & Khalan Weaponry, design & fabricate for the next generation group build. I think it would best be called an AR10-06 or better yet an AR06. In short, itís an AR10 for a 30-06 caliber cartridge using 20rd. BAR magazines.
I believe that most people who bought the AR45 receiver probably have already built an AR15 in 5.56 caliber and possibly two or even an AR in 9mm. Making the AR45 at least a second or third AR rifle. What made the AR45 COOL was the relatively odd caliber and high capacity Grease Gun magsÖÖSomething Different!
I believe there are several nice rifles available in .308 already, from a dozen manufacturers; AR10, FAL, M14, HK91. There is no point in building yet another AR10 in .308, as a finished Eagle Arms (Armalite) receiver can be bought for $180. What would be COOL is an AR10 in a different caliber with a high capacity magazine, like 30-06 in a BAR magÖÖSomething Different!
It turns out that BAR magazines are cheap at about $25. It also turns out that surplus 30-06 ammo is currently cheaper than the barely available .308 ammo. Most people believe 30-06 ballistics are better than .308. For me, the most interesting advantage is the capability of the BAR magazine to ALSO be used with the GIANT Winchester Magnum Caliber series in .300, .338, and my favorite .458!!!!! Now these arenít cheap shots, so use the 30-06 ammo if thatís a factor. It turns out that the Win Mag series is the same overall length as the 30-06 cartridges. The AR06 receiver has the potential to allow other experimenters/gunsmiths to have the capability to develop and grow into these new rounds! Think of an AR06 with a .458 Win Mag is to an AR15 with a .50 Beowulf.
The trick is going to be a design that allows the use of ALL the other AR10 components; Upper Receiver, Bolt assembly, Recoil assembly, Stock, etc. I know SolidWorks so part of the job will be to draw up the other components; BAR mag, Upper Receiver, Bolt, etc. to see if it can even be designed. So if any body wants to help in that area, that could be useful.
Iíve included a few links for ROM costs for BAR mags including a mag that has already had the feed lips formed for a .338 Win mag just to show itís possible.http://www.gunaccessories.com/Magazines/BAR/BAR.asphttp://www.gunbroker.com/Auction/ViewItem.asp?Item=78713992
Already formed for .338 Win Mag @ $45http://www.jocoemprise.com/rifles/browning/browningbar.html
Also you see the picture Iíve posted of the relative sizes of the mags & cartridges. I need to figure out how many of each caliber Win Mags will fit in a 20rd. BAR mag. The BAR mag is about .28Ē longer and about .055Ē wider than the FAL mag (donít have an M14 mag).

I would like your feed back about your interest in having Justin & Mitch pursue this concept and any other thoughts, which might move this idea forward!
