Awhile back I built an M4gery and had some problems with it extracting rounds. It would fire the round and the brass would be wedged in so tight that I needed to use a cleaning rod to get it out. This was useing both Win. Q3131 and PMC 55 gr fmj. I then decided on a whim one day to try some Fed XM193. Low and behold it worked! I then tried a total of nine other types of ammo with no problems at all! I even managed to fire 15 rounds in a row of Q3131 before it jammed up again. Since then I use those two types of ammo in my other AR's with no problems from them. Thanks to all the people that responde back with helpful info on the orginal post. |
