Hey guys. I'm new to the "Black Rifle" and really only have a few questions. I've researched and taught myself as much as I can about these rifles, so dont worry I won't be one of those new guys that worries everybody to death with random questions. I just bought my first rifle DPMS Panther A3 flattop.
  So heres the question. My rifle has a low profile front gas block/rail. Can anybody recommend a flip up sight to put on this rifle for the poor man? I'm probably gonna put a Magpul BUIS on the rear, but I just can't seem to find the right front sight. Any help is greatly appreciated.

I would take a look at YHM or Midwest Industries

I have a similar rifle and went with the Troy flip ups and they are awesome.  They were a little on the expensive side but I have no regrets, from my research the three companies that had decent looking gas block height sights were Yankee Hill Machine, Midwest Industries, and Troy.

They lay extremely flat.

And lock up tight.

Fellas I appreciate it. That rifle looks freakin good with that green dude.
