it should be .223cal 5.56mm i HIGHLY doubt its a .22 cal. cause those things dont even kill rats if i tried. Actually. the .22 is the best ammunition to kill a person with. only if you have a good shot. a .22 can enter the skull and never create an exit wound. it will continue to travel throught the brain until it is stopped by constantly bouncing off the wall of the skull and the friction of the brain mass. a little education!!
lol BUMp BUMP. nice pics not a fan of the pistol trigger foregrip. ill stick with my surefire one. and that scope is too big for my taste as well. BUMP
