Richard emailed me this week and said he was about to run a batch of Sako 75 Picatinny bases. All bases are stainless steel. The III action has 10 MOA of slope, and the IV and V action has 25 MOA. These are the ultimate press fit precision Sako bases. I have been begging Richard to make me several more for the last year, but he has been too busy with the war effort If you want in on this, now is the time or wait another year.
