well I decided to just see for myself how it worked, I figured worst case scenario if i couldn't get it working in 24 hours, I'd take it back.  Well not flawless, I was plenty pleased with the jam rate.  It only jammed once while i was loading my fifty rounder, not at all on the 25 rnders or the ten rounders.  We're not talking something you're gonna hinge your life or your ability to eat on, so to me that was an acceptable rate of problems.
