Time to get it straightened out to shoot as a Sporter in Bench Rest. From all I can find out it is a Marlin, Made for Sears. According to pics and descriptions it is a 38 or 39 year vintage. Somebody drilled and tapped it WAY OFF CENTER. Also had a ruger 10/22 base which was JB welded to the receiver because its not the correct contour. When I first got it it shot real well, just not enough windage to get on center. Also the base was a little loose so don't know how well it is gonna shot if He can straighten it out.
