you running a rifle length buffer on this? Thought the upper is using a mid length gas system. Any issues?

No issues at all.  the combination of the heavier rifle buffer and the mod bca does to the extractor results in smooth reliable cycling.   remember, wolf and tula have faster powder burn curves so at minimum its recommended h2 for x39. 

This is my third build with exact set up over past 6yrs and probably 15k total (my first and second builds I abused with cheap wolf ) and zero issues with tula, wolf, tiger, bear or NF in any.  

I'm just leaving the caliber, no more AKs etc,

Appreciate the info, have this same upper being delivered tomorrow, and was wondering if i could use one of my rifle length lowers with it.

It won't at all, I prefer it.  I'd change the hanguards though

bump

got a chance to try out the same upper this is using today, WOW. Worked perfect and accuracy was sub 1.5 moa with both steel and brass ammo I was using. Very pleased. Just too bad I bought it before your post!!!!

glad you are happy, they just work.  take a look at the extractor and notice the mod for steel case!  aids in reliability 

last bump before the move as explained up top
