OK, so yet another argument that they are the same, thus no reason for the second one....and completely not addressing my point? Are both equally modifiable? Is the barrel on the lower one, you know the type of thing that "makes liberals wet the bed" offer any kind of advantage to the other one? Seems to me that you are reducing heat and thus able to increase overall fire rate over time, among other things. If they are the same exact gun, then why does one have other features that, using your argument, would be completely unnecessary for manufacturing? A single advantage in one over the other beyond "looks" nullifies this tired NRA talking point.
