The Sako base is finished and installed. I hand made the base out of hardened steel stock to duplicate the early Sako Riihimaki tapered receiver dovetail so I can use the original Sako Riihimaki windage adjustable rings .The project came out perfectly. Left to do is Checker (matte) the top of the base in a 40 line per inch pattern to match the original Sako receivers .My bolt handle is also finished and is more fitting to an early Sako sporter.
