please no lasers. refer to M14 for spamtastic fail.
Well, it'd fit more on a pistol that is not as strong and because akimbo.
The m14 pretty much failed because nothing about it, the large mag, the huge ammo pool, the crappy sights and the way it encourages running towards the enemy is sharpshooter-ish at all.
Also 6 headshots to kill a 6-player suicidal FP. I don't think the mk23 can pull that off. Nope, they always clobber me to death.
The laser alone, well, I don't even use it if I have an m14 because it lags behind anyway and because I have a pretty good idea where the center of the screen is by now.
But if the mk23 had a laser, you could make it cost 500 and I'd still buy it.
A quick reminder where the bullets go without iron sights that slow you down would be invaluable for run n gunning or especially if you have dual pistols or if you whip the gun out quickly to kill some crawlers.
You know, what the berserker does.
