My Dad carries an M700. He started out with AEG's. He went through an MP5 and an uber upgraded M16 that was SUPPOSED to double as a sniper rifle. But, as fate would have it, my dad is incredibly picky when it comes to accuracy and he can't settle for anything less than....well...perfect.
So he bought himself an M700. Downgraded it a bit on the gas flow to have it shooting within regs, uberupgraded and fintuned the hopup and barrel adjustment and....well let's just say people are really starting to regret poking their heads over the tops of rocks now.
He's not the patient type one who likes to camp out for a half hour waiting to for someone to come by. But he is a crack shot, so instead of being a sniper for me and my squad mates, he's more of a "designated marksman" that is excpected to be able to take quick and fast shots with very little error margin. THe fact that he's using a sniper rifle only gives him the upper hand. He's more the stalker/support type, which is more typical of someone with a good AEG, but, in his case, he'd rather shoot one good shot that he knows will hit, than spray a cloud that only has a chance of hitting.
