Sarco walnut C stocks are nice wood but the inletting is horribly wrong behind the recoil lug. The A3 hand guards for them are hit or miss if they are even finished profiled right. It is like their stocks and hand guards were the mistakes from the stock factory.
Numrich C stock I recently picked up was a Minnelli with Italianwalnut. The hand guard they sent to match it was American walnut, not a Minnelli. Inletting was ok but still not correct at the rear of the trigger guard. It was stepped instead of radiused where the guard beds.
