Yes. I agree with stalker here. I wouldn't want to be shot by a level 2 rifle at under 100ft. 70ft is way too close. Even 100ft is too close. (except for close friends or CO's

) I wouldn't even bother centering my scope at that range as I'd be grabbing for my mk23 socom.
As with stalker, I'll always try to aim for kit keeping it well below the neck and face in the even of a flyer. Mags are great because the target won't feel it as pain but everyone will hear it hit. Dump pouches hanging over people asses are great spots too! I've even put a few shots on peoples boots in which they hated that I hit them there but thankful I didn't aim for the fleshy inner thigh I sometimes do with a lower fps AEG. lol.
