Case sticks after firing

[alwie]

I didn't see this asked (since I went through similar fun)... is the bolt cycling on firing?  if not, my first thought is that you aren't getting enough gas. 

I started mine of with the AGB closed and opened a bit at a time to get it to reliably function.  Those first rounds with no gas were no fun.

I dont have the gas system connected, no gas block and no gas tube. Was yours sticking with the gas off? I am just breaking it in before sending it out for nitriding.
