sick isnt the word when firing a 5.56 round. its brutal. i've had these since 2005. i was still living in miami at that time. so packing a lil sum sum for those house invaders that were runing around had something coming. unfortunately i didnt get any live action before i moved here in 2008. but its jus a lil reinsurace i can sleep at night. bad thing about owning a semi a/r is if you pull it and shoot an intruder with it you'd better have a fukin hellafied lawyer to bail you out. its not the same if you poped someone for breaking in with a hand gun. only excuse i can give is that my dpms was the only thing i could reach for loaded.
