One of the reasons that the front sight is part of the gas block is that it makes the front sight assembly is stronger.

It needs that extra strength because the front sight is so high. That's related to the rear sight being so high. Which is why there is/was a carrying handle which is because the butt stock is straight which is because the bolt carrier group recoils straight back into the the buffer tube which is in the stock.

Pant, pant, pant.

I think this is supposed to end with, "And this is the house that Jack built" or something like that.
