I'm new to the AR world and to this board.  From what I've seen there seem to be a lot of well informed people here.  I just bough my first AR - a DPMS Recon. The rifle was bought new and my first time out I ran about 100-150 rounds through it.  I could not get the rifle to cycle properly.  Almost every round had to be chambered manually with the charging handle. I used the steel mag that came it and a couple of new P-mags with .223 and 5.56 rounds..  Same issue with each mag.  Disappointed, I took it home and cleaned it.  I also checked this site and others finding that it may be a lubrication issue or buffer tube spring.  Liberally lubing it and leaving everything else unchanged I went back to the range and bought a different brand of ammo hoping to eliminate the problem.  The first round fired but it did not chamber the next round.  I manually charged the next round and out of 40 rounds fired, I had two more cycling issues.  The rifle would either not pick-up the next round or it would pick-up the round but it would not feed into chamber.  The rounds that would not chamber would be sitting at an angle.  The guy next to me at the range had a DPMS as well.  He had not experienced the cycling issues but he did change his buffer spring after only 20 rounds.  Any help would be appreciated.

If it was bought new, send it back and make them address the issue.

Just for giggles,  what ammo was used?

You shouldnt have to change a spring call DPMS -

Thanks everyone. I'll try the industry post and see if that helps.

If it is not cycling at all I would check that the gas block is properly aligned, make sure the gas tube is not bent check gas key on bolt make sure it is not loose and also make sure your gas rings are sealing.

All this you can do yourself eye ball the gas block, take off hand guards and look up into upper at tube, to check gas rings install bolt with no charging handle put it all the way into battery and see is gravity can make it fall out if no it passes.  Might just be something simple.
