I sort of like the idea of having iron sights, and I notice there
is quite a supply of used 110 barrels for sale with iron sights.
The only problem I can think of is that the head space may
be a problem with the iron sights sitting perfectly straight up on
top of the barrel. Best case, I imagine, is that you could
screw the barrel onto a new factory case and see just
where the sights are, then if you back off just slightly
and the sights are positioned right, you should be good
to go. On the other hand, worst case, you screw the
barrel onto a new factory case, and the sight is way off,
now you just remove the case, go ahead and turn the
barrel to have the correct position for the sights and then
tighten the barrel nut. Now though you don't have enough
head space, and you need a chamber reamer to just
go slightly deeper on the chamber cut to get the proper
headspace.

Have any of you actually made a barrel transfer putting
on a barrel with iron sights on a different action than
the one it came off of? If so, how did it go?
