Holy s*** Keith - reading your post it sounded like you were describing my 15 minute job! Same problem with the left side and sounds like the same solution with about the same tools. I ended up drilling out the head of the bolt inside the stock risers until I was able to POUND the headless thing out the bottom. Felt like a total moron; glad nobody was watching. Did get the spacers and the bars on OK, though. What a cluster. I am happy with the results but I wonder if I should be allowed to handle tools around the BA.....
