Besides the offset pin, are there any other options available to attach a standard upper to a large hole lower?

Thanks!

Not really, besides having your normal upper bastardized to large pin specs.



I take it you've figured out just how Full of Suck large hole is? It's the one thing I truly detest about my RR. :-\



Well –– maybe there is one other answer... If you have some attachment to your lower, you can have someone like M60Joe (I think that's his name) pin in offset bushings to reduce your lower's front holes to proper size.

Daniel Defense makes a large hole flattop upper.

To keep mine from binding, I hit the center part with a Dremel. I've got a number of big hole uppers, so really don't have much call to use a standard upper.
