I've heard Uzi or modified Uzi.if so, how are they modified?

A notch is cut for the AR mag catch on the left side of the mag about 15/16" down. But really you want buy the purpose made 9mm AR mags that have a channel at the back for a protrusion on the follower to active the bolt hold open -- the modified Uzi mags lack this and don't activate the BHO.

You can usually find them at Midway or Brownell's for ~$20 although be forewarned they usually don't feed quite right the first couple of times out until some finish wears off inside the magazine body.
