My new BVSS 308 has a lousy action fit. The first thing I noticed is that the magazine clip doesn't even come in contact with the pillar. As I tighten the rear screw, I feel it as being sort of squishy. It definitely does not come to an abrupt stop like the front. The pillar wasn't even installed square, it a little rotated clockwise. I need to relieve some wood from under the mag clip and bed that area, but I can't figure out how to remove the stupid thing. It appears like you would push on the blued steel tab, freeing the mag from the clip, but that doesn't work. The book says to simply affix the clip to the mag and push it back in place "if it falls out" during dissassembly. That's a joke.
I've already floated the tang and that helped some with grouping, but this thing is definitely binding somewhere.

So how do I get this thing apart to fix this area?
