"I got it a month ago but still haven't shot it yet do to the weather this winter. Everything seems to be well made on it except the ATI stock. It is sloppy and will be getting replaced very soon. I will update after the weather breaks and I can shoot it."

"Rifle arrived within a week. Everything is in working order. Trigger is crisp. No creep or sandy feeling in the trigger like some reviews had indicated. There was a small scuff on the bottom of the handgaurd. It was about the size of a piece of rice. It will not be the last one my rifle gets as I plan to use it for hunting. I wouldn't hesitate to recommend this to anyone. I will be replacing the ATI stock for a fixed stock but that is for my own personal preference. Everyone loves the color and is asking me what it is and where the can get it."
