Well the poll time has ended and I left it up for more than a month without realizing that I misspelled "modern". Oh well. I don't get paid for this, you know.
64% think that camouflaging a weapon should be the personal choice of its user and 11% think that firearms shouldn't be camouflaged at all. The other 23% are with me and think that modern small arms should all wear some camo. My reasoning is that if you are going to wear camouflage it is silly to have your weapon stick out. Don't believe that? Check these out.
Look at how much more the weapon stands out from the background.
Another thing to consider is that many elite units like the Army Special Forces, SEAL teams and SAS often do camouflage their weapons. And if they do it, everyone should right? ; ) Also, modern "paints" like Duracoat are very good at protecting a weapon from scratches and the elements. Surface rust can begin to form in a day or two on unprotected surfaces. God knows what happens when soldiers get salt water on a gun. I shudder to think.
Nightvision can also make blued and parkerized weapons shine like they are glowing.
Proof you say?
The weapon on the the top is painted, I believe with bowflage, and the lower is a plain AR-15. Notice that the parkered aluminum is very visible. Modern weapons have significant amounts of plastic, and it does not take any more money or time to make them in colors that blend well like olive drab and coyote brown. For those of us who are not paid to be shot at, this is not as vital an issue to be sure. And some people just don't like the aesthetics of camouflaged guns. To each his own. And I've seen some pretty awful paint jobs. But I dare you to look at these and say that they look bad or wouldn't be an improvement over the old standard.
Or you could go this route.
