If anyone here can share some information about this rifle, I would be very appreciative. I have an FN PBR .308 rifle, I want to use the receiver as a donor for a custom build. I am finding it difficult to find information to confirm in my mind that this receiver is actually a Winchester short action Model 70 with the hybrid control/push feed action. The receiver bolts are 7 1/16th from center to center. I think I just need some new bottom metal and I am likely going with an H-S Precision stock. Barrel will likely be a Kreiger. Will be assembled by the 'smiths at the Vets Shooting Center in Russel, Arkansas. Haven't settled on caliber yet. Thanks.
