I thought I would update this thread.
My order was placed on Black Friday. Through several emails I had been getting the run around about a shipping time, always getting an answer of "3-6 more weeks". I called last week and asked when my rifle would ship and was told 3-6 more weeks and that they do not have the parts to assemble the rifles they already took money for. Needless to say I cancelled my order.
I then contacted PWS and ordered a MK216. It arrived at my FFL 4 days later. On top of that, they offer a military discount. So, it was a bit more than the Stag, but it's got adjustable piston to shoot suppressed. This thing is really nice. I installed an ambi safety, YHM flash hider can mount, and a Burris MTAC 4-16. I hope to shoot it when this snow melts and I can get up to the range. I plan to try out the Magpul, Lancer and ASC mags.
