Jogged my memory yah I was a member and a contributing member at roderus homebuilders before the payment was required nonsense
yep Greymans build it was
TRX is right about the plastic, wood & etc lowers, but I keep reading threads about using the old tannery/other makes of cast lowers, claiming to be not satisfactory, on that note my tannery lowers have held up
Has anyone tried using an AK lower (w/ AK .223 mags) adapted for the AR-15 upper ??? The front trunion would be a simple hinge block and the rear trunion would serve as the stock retainer fitting. Laying an AR upper on an AK lower should provide some useful insight as to mods.
I've been working on a sheet metal AR16 in 308 Winchester (AR16) design. I was planning to use an AR10 bolt (with n AR10 barrel) but the angle of the bolt cam pin with the position of the extractor makes it a difficult fit in a squared off bolt carrier. I think I may go to the round AR10 bolt carrier and the upper may be an AR10 upper or maybe a steel tube design.
While that was kinda my original idea, I've been more looking at the AK receiver bending simplicity married to a more AR lower shape. Hard to explain, but I think you get what I mean.

I've gotten away from that in my drawings now though. It will be a little more complicated, but should still be a simple thing for the home builder to do. I want to get all of my dimensions and plans written down, then see if I can get one of you pros out there to put it into an actual proffesional drawing format for everyone's use.
The AR 180 and 180B use a square carrier.

So now I think I might make it a round tube receiver and just use the factory AR10 bolt carrier. If I was going to make one in 223 I would use the H&K G36 bolt and go with a square receiver.
