Saw a Sendra stripped lower repaired by Oly. for $425. I ask the guy what was repaired or if it was just refinished. He said there was a small crack where the buffer tube screws in, and you can't even tell now. Well the lower was cut in half and welded back up and ground off. I weld for a living. You could see where it had been re-welded. I pointed it out to him, he got real mad grabbed the receiver and said I am busy. It said right on the receiver repaired by Olympic for Sendra. It probably would have been ok for a pre-ban shooter, but I couldn't beleive how this guy lied to me and got so mad. I wouldn't buy it for 2 cents after that.
