ANy current interest in this project?  I am very interested in a 10% or at least drawings on this.

I'm (still) interested. 'Course the cheap BAR mags linked earlier in the thread are no longer around but there are others (not quite as cheap tho  )

The extra cartridge length looks (to me) like it'd call for an entirely different firearm, not just a lower; if the round on the left is standard .308, the rest of them are longer enough to where you can't reasonably fit them into an AR10 upper and have it cycle, as the bolt doesn't have enough travel to accomodate much longer of a round than a .308.  I think you could make do with a standard (rifle) length AR10 receiver tube, if you put a short buffer in it, but I don't know if the AR10 operating spring could support the extra travel.

Now that I've played with the AR10 platform a bit, I'm tempted to make something bigger, but the next step (with any level of support) is into the Armalite AR30 (.338 Lapua) realm for which separate spare parts are not exactly advertised as readily available, let alone at a budget-minded price point.  My problem personally becomes, once you get bigger than the AR10, if you want an AR type configuration, you're into probably a one-off bolt, bolt carrier, etc., and that's beyond what I feel I'm qualified to build at my present level of experience.

I have looked around.  There are several sources of BAR mags available.  I do agree that probably this would be an entire custom design including upper and bolt.  Anyone interested in undertaking this?

you know I actually am determined to get my next AR rifle in 358 Winchester.. The recoil is a issue but this rifle hits like a sledge hammer! all the military should switch over to 358 Winchester ASAP
