I've noticed when I set the barreled action back into the stock that I can squeeze with thumb and fore finger back and forth where each pillar is at and get a rocking motion? Should the action contact anything in between the two pillars besides maybe, the sides? but that shouldn't make it rock. I've already relieved some material at the tip of the forearm to stop the barrel from making contact while on bipod or rest. I plan to replace the trigger with a #510 Timney trigger and also a Bell & Carlson stock when funds allow. Thanks for all info!
