Walter,I can get you those rings. I agree with Sciguy... one of the great features on the Retays is a REAL weaver rail built in. It won't get better.Richard
Unless the one-piece is adjustable, you are not gaining anything. Weaver picatinny rails have slots because the screw on the bottom or the ring base lays in it and locks the position of the ring on the rail. You are probably having a hard time finding what you are looking for because it would really be redundant.Richard
Are you sure you will need to quickly disconnect a scope? You'll be paying for that luxury.Richard
