I'm currently saving up for a BAR to use mainly for sparring, but other players have told me that I should save up for another gun such as the M4. In your opinion, what is the best gun for sparring and why? Personally, I'm looking for a gun that is generally good for sparring; one that reloads quick and has a fair amount of spread. Any answers would be greatly appreciated! Thanks!
Edit:
Gralats are not an issue here. I know the BAR costs a lot more than the M4, but that doesn't matter. Only the statistics of the guns do.
