I could see that line of thinking in the military but in the civilian sector chances are you will be using your own rifle. In that case, I would adapt and customize the weapon to suit the intended user. It's a luxury of personally owning firearms rather than having to grab one off a rack when the time comes to utilize it. Why force a square peg into a round hole?

I've never had to borrow guns when I shoot matches, because mine always work, but I have had to loan them to other people to get them through the match. If you are a hunter the same scenerio could apply...your gun goes down, but your buddy has a spare.
IMHO the AR15 is one of the most ambidextrous guns out of the box there is. You can learn to effectively operate all the controls from the left handed perspective just as efficiently as someone else can right handed...gadgets will never compensate for practice, but once you have the skill they can improve your perfomance.
I've shot enough and done enough mag changes now, that if I put the ambi catch on my rifle it would screw me up...especially if I put it on one of my rifles and not all of them. I have 4 AR style rifles, I don't want to spend $280.00 making them all the same. I'm a firm beleiver in continuem of training...the more you can do to make your competition, hunting, and self defense firearms all basically the same in terms of sight picture, grip, length of pull, and operation the better. This is one of the reasons I designed the SST-870 AR15 stock adapter for the remington 870 shotgun. If you only have one rifle and that is all you ever shoot, this isn't so much of an issue.
This is just my personal opinion, a lot of the left handed or ambidextrous stuff on the market I have tried I haven't cared for too much. Dedicated left handed guns are the worst IMHO as they are often adressing a problem that does not exist and you will have a hell of a time selling it later if you want to.
