I just got a new m4 and took it out today
wow, it sure looks nice, but I'm having trouble with my shells.
After 4 rounds, or so, the m4 gets stuck.
Either it doesn't eject or doesn't cycle to the next round.
I was wondering what you guys know what is going on.
The ones that got stuck were the Winchester universal #8.
These shells work just fine in my other shot gun, but not this one.
Which brands do you guys use in your m4's
Thanks guys
Pete
