i got the pillars off ebay that i've seen others mention on here. they are supposed to be for a 110 and have the curved contour that fits to the action and the notched rear pillar to clear the sear. they arrived and they do not clear the sear or fit to the action. the action rides hi on the top side edges of the contoured pillar, not flat against the centerline. a decent amount of material would have to be removed to clear the sear.

should i just grind the contours flat (will it still clear the stock - i haven't drilled the stock to test yet cause some pillars are 5/8 and some are 9/16)? to grind the notch to clear the sear would leave a thin wall next to the screw hole. is that sufficient?
