Hey guys. John Lewis with Carolina Precision Rifle is currently building me a rifle. I had requested a karsten cheek piece in the original order but he can't find one. I guess they are all out of stock. Does anyone have one of these they'd be willing to sell me or can someone recommend an alternative to the karsten? I know its not going to be the end of the world if I can't get my hands on one before he finishes the rifle as I can always add something like this myself later. But......
