Has anyone used or felt a Greyboe rifle stock? I won a Ruger American 7prc and I really do not like the stock. I found that Greyboe sells a mini chassis that fits a few of their stocks so it would be upgradeable at a later time if I decide to go a different route. I am looking at their flagstaff stock.https://www.grayboe.com/products/grayboe-flagstaff-rifle-stock
