Awesome thanks guys. I got the fellow's original bill of sale and the break in procedure. I've already stripped it and cleaned it. Of course, it's just like any AR platform. One thing I did notice is on mine, I had to loosen the carrier screws a bit to get the cam enough room to slip out in order to strip the bcg. Not a big deal, just something I wasn't used to doing. That's on my list to ask GAP about as well.
Aflick, you're welcome to shoot this sucker anytime you want. I haven't got glass on it yet but hopefully in the next couple weeks. I'm going to use a Larue LT104 mount that I had from another rifle.
