as to that magazine disconnect, you tube is your friend, number of video's on how to do ti.
i did three or four of them last fall using youtube, it isn't rocket science.
I watched a couple of YouTube videos on it, tried it, and ran into problems. Took it to a gunsmith and he said you have to remove the trigger to remove the disconnector, which contradicted the videos. Anyway, he did it for me, and charged me twenty-five fricken dollars.
Huge improvement in the trigger pull, though. About two pounds lighter break, and all the grittiness in the take up disappeared. It's an awesome trigger now.
