I have a Springfield 3-point scope mount for sale. It has been on an M21 for the past few years, but was recently removed to sell the rifle sans scope and mount. It includes the stripper clip guide replacement. Very good condition.
I'm asking $100 shipped.
ETA: I'm not sure what it's called. I was told it was a 3-point, but it may be a 3rd Gen instead (that's what it looks like from other pics of 3rd Gen mounts.) The buyer received a picture of what he's getting, so I suppose he knows what the heck it is. It has "Springfield" on the side of it, it is made of steel, and it has two big screw knobs on the left side. One of the screws goes through the receiver and into the replacement piece for the stripper clip guide. So, you tell me, what is it?
