So it has been awhile since I had been able to ge to the range and yesterday I did just that. Here is what I have done and now the rifle runs like a champ. First, I replaced the extractor with a JP Enterprises unit and readjusted the gasblock replaced the buffer spring with a factory spring and also installed a KynShot Buffer. Rifle cycled and ejected as it should but would not lock on empty magazine. Second, adjusted the gas block from scratch again and it still would not lock on empty mag. Third, Removed the KynShot buffer and replaced it with a Armalite buffer 1.5oz heavier than the factory and presto it locked on an empty, now readjusted the gasblock and it cycled 150 rounds no failures keeping a consistant 1/2" group at 100yds. No I am a happy camper and looking forward to completeing my build with a forearm, trigger swap and Cerakote. Thanks all for the help and advise.

OPFOR: Already done swapped the original spring back and put an o-ring on and noticed a considerable difference in tension but that being said I will order another DPMS extractor and spring for the spare parts box. I have a lot of experience with AR-15's and built many but this .308 world is so much the same but yet so very different and I am learning all over again. Thanks for the help.

Survivalshop: No it is their AR-15 Upgrade, as I thought it would be a cheap fix if that is what it was since this has been going on for 3 weekends now, that i why I was leaning to the JP 308 Enhanced Extractor to see if that is what it would take to fix that issue.

OPFPR: That is the main suspect at this point, so I think I might just invest in a JP Engineering "Enhanced Extractor" and possibly their "Enhanced Buffer" and spring pack to tune the recoil a little more so to remove any doubt it is over gased. All the ideas are much appreciated.

98Z5V: Mags are not dropping in the video it is the same shot ran 3x's (Fully Speed, 50% Speed, and 10% Speed) The issue is the round is not ejecting and seems to lose extractor engagement so it does not get to eject correctly. Robocop1051: I have replaced the extractor spring with a Bravo Company and used the insert and o-ring. I will break it down ths evening and check the spring. (and may sound crazy but what are you refering to as aD-Ring)

OPFOR: Yes the ejector creates even pressure when trying to place a round or empty case into the bolt face. which leads me to be that it is the extractor. I have adjusted the gas block to the point it locks back on an empty magazine and additonal 1/4 turn to possibly eliminate the over gassing issue.

Before I even begin I know there are a number of posts about this. I have a Remington R-25 hat has been a project for sometime now and I have done the following. Rainier Arms 20" Match Barrel PRI Adjustable Gas Block SOCOM 7.62 Muzzle Brake Polished and adjusted trigger Bravo Company enhanced extractor spring kit MAGPUL PRS Stock I have taken it out to the range a few times and it is not cycling correctly. It is accurate as I could expect shooting dime size groups at 100 yds but for the life of me I can not get it to feed multiple rounds. It will pull the case out of the chamber and drops it on the magazine during most shots, then on occassion it will eject it to the 4 o'clock position. I have a video posted on Youtube of the issue. I feel the next step is replacing the extractor. Any help would be grealty appreciated.
