If the mag was jammed with pellets and the O-ring was missing, you did not get a refurb. Somebody grabbed a box that had been returned and shipped it without checking a thing. A refurb should work, after all the word "refurbished" means somebody has looked the item over and fixed any and all problems.
Well I'm glad I was patient, Tom from PA called this AM and after figuring out what could be done, they sent me an RMA and label for the gun and are sending me another BRAND NEW one, plus throwing in a full inspection and 10-for-10 ... NOT that this is going to stop me from saving for a 909/Sniper, but all in all it looks like everything should finally work out !!!
