You have to laugh at the BF3 community some times.
Prior to the patch, nobody really used the M26 or had heard of it. There were no stupid accusations about you using it, and it was just another weapon. Heck i'd only heard of it when seeing somebody posting a video of them using it and I had to ask what it was. After that, i had absolute riot with it:

Then THAT video happened and let the genie out of the bottle that the M26 had been bugged in the last patch and every idiot started to use it.
So reading the youtube comments on this video, make me laugh :
You notice he's not underslung it. Its used stand alone so its not using it the bugged way. Just the normal way - the way it was before the patch.
And look at the youtube comments moaning about it. None of them would have said a thing were it not for that video. Now that video has made the m26 public enemy number one, for no reason at all. Its a semi auto shotgun that requires accuracy. If you don't make that first shot count you'll likely get shot. The noob cannon was the USAS, where you could just run round on full auto with frag rounds and not even have the hit the target as the splash damage from the walls would be enough to kill them. But now because of "THAT" video showing the bug everybody is up in arms about it.
The video proves just nicely what i've said before - it was pretty awsome before the bug. As somebody who used it a lot before / after the bug, all the bug did was extend the range a bit. But now I can't use it any more, as every server admin under the sun will ban you for using the M26 of any sort, regardless of whether you underslung and use the glitch or not.
