Nearly finished with DPMS .308 build. Had several issues with this build. ( My first ever.) Now another issue; When rapid firing, shells get jammed up-stuck. Almost as if second shell is trying to get into barrel before 1st round has time to eject. Both shells wind up being impinged by BCG and second ( live ) shell is bent when I fish it out. Don't want it going off in my face!! I have used mags from two different manufacturers. Both seem to be doing their job. Help would be much appreciated. Thanks.

 Under Gased or more likely a Ejector /Extractor issue . Disassemble both & inspect for Burr's or debris , check Springs & if there is a donut on the Extractor Spring , install a DPMS duel Spring set up .

 Sometimes the Extractor can hold onto the spent Cartridge too long & cause this issue . If you have spares , replace one or the other at a time . Inspection may show something .

 Photo's of said components would be nice for us to look at . A rough Chamber can also slow the BCG down enough to case an issue also . 

 No issues with slow fire ?

It rubs the lotion on the bolt... slow it down until its properly broke in? How new is this ?

Extractor is definately holding on to cartridge too long. I can use charge handle rapidly and shells eject perfectly.Just when I try to shoot using trigger the shells bind up to the point of being bent. It will not shoot multiple shots. It will bind as second shell tries to go into chamber and first shell is slow to extract. Causing the jamb.Hope this helps. Thanks

look something like this ?

If so , inspect the Ejector & Extractor & their Springs , change out the complete Spring & Ejector or  Extractor one at a time to see which helps . Make sure the Components are 308AR , stay away from the Donuts , use DPMS Spring set up with Extractor .

   This particular Rifle all it took was changing out the Extractor & its Spring set up with a factory DPMS set up . Rifle functioned flawlessly after change out .
