I love mine. It shoots smooth and fast as fast as I can pull the trigger. I bought cheap Federal low brass dove loads and had zero problems, 150rnds. i bought the folder, but I doubt I will ever shoot it folded. I would buy the $799 one and leave it that way. The stock looks badass. The cheek rest is the only thing I am going to modify. I am going to dremel the notch a little bit. It tends to move with the recoil. The notch is kind of shallow. I think another 1/8th of an inch should do the trick.
Fyi, i did hand cycle the bolt a couple hundred times in front of the tv before taking it to the range. Go light on the lube. I dont lube the puck, gas prt area or anything other than the contact points on the bolt or rail. This is what i read recommended somewhere else and mine ran flawlessly.
