You can also get a gas block with a rail on it and mount whatever kind of iron sight you want. You just have to be sure the rail is high enough or the front sight is made gas block height.

I have a YHM that I'll let you have cheap if you want to try it out. It worked fine, but I put an adjustable gas block on mine, so I don't need the YHM any more.
The YHM folds in a way that doesn't extend back and hit the forearm, with others you will need to check that it will clear the forearm when you fold the sight. Some people reverse it so it folds forward if it hits the forearm. That will catch vines and stuff, though, if you carry it through brush.
There are Youtube videos of mounting the gas block and removing the standard one. You will also need to knock out the roll pin retaining the gas tube in the gas block.
Getting the alignment right when you put the new gas block on is the tricky part. The manufacturer usually has instructions because it will vary a little with the different styles.
