Hi alll...
I have not looked at the DPMS lower but I have looked at the AR-10. Also, I do not own an DIAS but I do have a rLL...
Now, I have looked at using the Lightning Link in the Bushmaster 308 and AR-10 and it is my oppinion that the Bushmaster will be MUCH harder to get to work with the Lightning Link then the AR-10 while I think making teh AR-10 work with teh Lightning link wil be rather easy:
www.quarterbore.net/forums/showthread.php?t=177As for the DIAS, the big problem with a DIAS is that it fits around the rear takedown lug of the upper receiver. There is no way that you can (if you were foolish enough to want to) open up the body of the DIAS such to allow the DIAS to fit around the rear lug in the AR-10.
One way around this would be to have a skilled welder weld up the rear lug and receicer holes for the rear takedown pin and then reshape the upper receiver takedown lug so that it fits inside the DIAS and then redrill the pivot pin hole to use a smaller AR-15 pivot pin. I am not sure if this would be a problem with a full auto 308 but in the spirit of can it be done... I think it could be done!
So anyways, making the AR-10 run with a lightning link looks VERY easy. I have not done mine yet as I want to formulate a well written and targeted letter to the BATFE verifying it would be legal to bolt an AR-10 to my machinegun (remember the AR-10 in this example is a PART added to the Machinegun (LL or DIAS) and NOT the other way around...
Fun stuff huh?
