Okay, thanks guys. Today when it was feeding (2) live rounds I was only using the DPMS mag. I'll try some other magazine options and experiment with only brass cased ammo to see if I get better results.

Range update... The gun is starting to loosen up and if I keep dripping motor oil in it every few minutes it seems to shoot better. Its still not great but I can now shoot between 5-10 rounds per mag without jamming. Now when the gun jams it seems to try and chamber (2) live rounds.....any ideas what would cause this? I'm not using and NATO 7.62, its all bought now commercial 308win. I've been changing between cheap stuff like steel cased Wolf,Tulammo, and also more expensive like brass cases Federal, Remington and both seem to produce the same results so far. Attached it a photo of the problem.

thanks for the quick replies. I just removed the trigger and hammer to check springs. everything looks correct. I went ahead and reinstalled a different MilSpec. FCG just to see if it will help.

after checking all listed items from previous posts I took the DPMS308 out again this morning. Now I'm able to get 3 shot intervals before it jams. Still annoying but its an improvement from it being a single shot. now when I shoot it, its...1shot....2shot...3shot....4th live round is chambered but trigger acts like the hammer is still up or the safety is on. I checked it several times once this happened by removing the upper and saw that the hammer was cocked and ready to fire and when I put it back together it would shoot the next round. could there be another issue with the firing pin? When I took it apart to clean it last night, I couldn't believe how easy the firing pin retaining pin fell out. I didn't even touch it, it fell out on its own...is that normal?

I had to wrap up the LR308 since its a Christmas gift for my father in-law. Once he opens it, I can proceed to trouble shoot the problem. I'm taking down a list of notes based on all our your suggestions. I'll get back at it in a couple days. Thanks again everyone. I really appreciate being able to join a forum and quickly getting loads of useful information from knowledgeable people.

Okay sounds like the only thing left that could possible be causing it is a gas port/gas block area. I'll check it tonight. Thanks again... Note: It shouldn't be a spring/buffer issue. I bought the A2 stock as a kit directly from the DPMS dealer at a local gun show and he made sure I had the correct spring/buffer for the .308 build. I also bought an extra LR308 A2 spring & buffer (for extra parts) from that same DPMS dealer and I installed these yesterday just to verify that it wasn't the problem. So to clarify, I have tried (2) LR308 A2 springs, and (2) LR308 A2 buffers and both have given the same result.

here's what the empty casings look like

Tested it again yesterday afternoon. So far I tried drenching it with RemOil and it still jammed with every round. When I charged the chamber with only (1) round per mag. and shoot it, the bolt locks open about 50% of the time. All of the spent casings have a scratch down the side with a dimple at the base of the neck and the neck opening is crimped. I will buy a can of air tonight to test the gas port. Thanks again...

Okay, good idea. I'm headed out back now to try your guys' advice. Be back later with the results...Thanks again.

Hello all, I just completed my first LR308 using mostly DPMS parts. Once I charge the BCG it will shoot the first round fine and eject the empty casing but will not feed the 2nd round or it will feed it half way and and the bolt will be locked halfway open. I purchased the complete DPMS oracle upper already assembled so I assume it shouldn't have any issues... ??? I built the lower myself using a billet lower and a CMMG lower parts kit. The stock is a DPMS A2 assembly, and I made sure it had the correct .308 spring and buffer. I tried (3) different magazines; metal DPMS mag, 7.62 PMAG, and ACS metal. All (3) had the same problem using multiple types of ammo. First shot goes bang every time but never a second shot without pulling the charging handle and ejecting a live round so it will feed the next round, then bang again....and so on.... I tried disassembling it again and oiling all parts really well. I also tried another A2 .308 spring and buffer and nothing has helped so far attached is a pic of everything I have tried today. Any additional info would be great. Thanks!
