I can not begin to express my satisfaction with the product that Richard Near has provided to me, without telling you that it has taken a number of years to get a base that would work on this 591 SAKO action. Now having gotten that said, let me emphasize that this base fits like a glove. The workmanship exceeds any and all I've seen from any other Mfg. Richard Near has to be congratulated for this work of art. Once I have the rings to get this system up and running I will post pictures. For those in the market for the finest and when only the vary best will do, look no further than to Richard Near!
