Well it finally drove up an hour ago. I had the old stock off already, and with some shorter 1/4 x 28 screws it dropped right in, and fits like a glove. The palm swell is thicker than a McMillan, but it positions your trigger finger just right. Still waiting for the SSS nine round detachable mag. The v- shaped aluminum block holds the action very snug. I'll try it in the morning.
