Anyone running a 7.62x39 upper on their 5.56 lower? If so, how has reliability been? I've been thinking about building one, but wanted to hear some feedback. Thanks!

They work.
the problems it the limited mags
limited rounds in ammo
feeding problems
factory vs reloading
bore dia vs bullet
if you do a true 762x39 then you will have a 311 bore
if you reload and want to pick normal 7.62 bullets they will be 308.
some of the barrel makers are using a 308 bore and if you shoot surplus then it is 310 to 311 ammo really heating the barrel and causing extra wear.
