Look for a Savage Long Range Precision (LRP) action. It is the Target action and trigger with the center action screw removed and the bottom opened up for DBM. See them only a couple times a year on here for with just the action for sale. Try looking for someone selling the whole rifle and strip for the action, if needed. It's an excellent action
I have 2 lrp's in 6.5 creedmoor. Would possibly sell the barreled action off one of them. Neither has more than 100 rounds on them. Pm me with an offer
