seems like every time I look up info on the AR15/M4/M16 you eventually find referances to the lack of knockdown and guys wishing they had a 308 win,6.5 grendal ETC.
when the first AR15s were used in viet nam they were very effective WHILE they were still functional, and the main complaint was due to jams and functioning issues, once those were resolved thru chrome lined barrels and more frequent cleaning.
now Im well able to beleive that there isolated incedences where guys hit center mass with a 223 and mil. spec. ammo can shrug it off for a few seconds or even minutes but without body armor I can,t see decent hits not proving to be fatal in a few minutes, Ive seen DEER shrug off a hit from a 30/06 for a few seconds before it even looked like there was any damage done.
but what happends to those combatants after a few minutes?, it the 223 rem
5.56 ammo really that pathetic that hits don,t prove fatal?

anyone with experiance here!
do the well hit combatants not only shrug it off but continue to function and keep fighting minutes or hours later.
