Are there any issues with tightening the barrel nut with the barrel clamped and the upper floating
as opposed to clamping the upper and tightening the nut?
Thanks

Not sure if I understand your question...you're asking if you can do it backwards? Standard procedure is using a vice, block for receiver, secure receiver in block, tighten vice, then tighten barrel nut to spec (30-80ftlbs) while aligning holes for gas tube. That's the way I do it, never tried to clamp the barrel and tighten...

It wont work. Go into your kitchen and try screwing the top onto a jar without holding the jar itself. See what happens when the lid starts to get tight. That's effectively the same as what you are talking about.
Not gonna do it.
Thanks!!
I agree with the others, a receiver block is better.
However.....securing the barrel will work as it is even the described method in the army technical manual. I think you'd have to be unlucky to shear the pin - but I'd still advocate a receiver block.

you'll get Al scuffs on the outside of the barrel that will take time to remove.
