Took the AB2 out for a few rounds this AM.  There were some other guys there with scoped rifles and bipods trying to gong those tanks which are 400 yards away. I walked up with the M70 and slid the rear sight up to the range and the third shot I gonged that welding tank.  There was a lot of sun glare but I continued to gong it a few more times with that magazine full.  Not bad for Monarch ammo at 400 yards hitting a 10" wide object.  These M70's are some very accurate AK's for sure.
