Does it have an adjustable gas block?

Welcome. Were any of these reloaded ammunition? Need more specifics on the types & makes of ammo.
Did you lubricate the bolt carrier group well? I run my large AR's with a thick coat of oil on them, mainly Slip2000. Quoted:

The GII hunter does not have an adjustable gas block. None of the 6 introductory GII models had an adjustable gas block that I saw at SHOT. |

No reloads...150 grain Remington UMC to get it on paper, 165 hornady superformance sst's just cause i had it laying around from a hunting rifle, 168 GMM, 175 Fioochi match rounds which have serria match king bullets loaded in them. I did lube the bolt carrier pretty heavily from what i though with just rem oil i had around. I know dpms recommends remington "claw" oil for lube

Not sure that Superformance is such a good idea in a gas gun.

I did lube the bolt carrier pretty heavily from what i though with just rem oil i had around. I know dpms recommends remington "claw" oil for lube The Superformance line is notorious for exhibiting harsh treatment on brass in a gasser, because the burn curve maintains higher pressures down the barrel, while optimizing peak pressure in the chamber to stay away from max. This is indicative of a slow-burning powder meant to drive the longer bearing surface bullet at higher mv's from a bolt gun. 
When you hit the port hard with a slow burning powder, it has violent effects on the operating system. 
Superformance in Gas Operated Firearms Do you reload? I got into .308 gassers knowing that I would only be hand-loading for them, except for my 1st AR10, which was an Armalite AR10T 24" barrel blaster that shot amazingly well. I can't think of many factory loads that I would even consider to shoot through a large firing pin hole AR10 today. High pressures and slow burning powders mixed with long bearing surface bullets (the ones I shoot) = port pressure issues unless you hand load. |

Pull the bolt out of the carrier and make sure the gas rings aren't lined up. Had that happen to be the case on a brand new ar15 before...

I would call DPMS, something is not right, my g2 hunter has shot 147, 150 and 168g ammo from several manufacturers with no issues at all.

Loose that crap rem oil and soak it down with 5/30 mobil one and hand cycle the action about 200 times then try it again. If that does not work send it back to DPMS.

Ordered up an new dpms gii hunter, was at the range today and it will not cycle 150, 165 or 168 grain rounds, ran 175's pretty well tho. All the casing have heavy scratch marks on the and some of the casings had marks from the twin ejectors. It will fire the round but not push the bolt back far enough to catch the next rd and feed, it did fail to eject a few rds when i first started shooting. Any advise or help would be sweet. Thanks Brent....Just an FYI im pretty new to the AR world and new to AR15.com Thanks All of the GII rifles are test fired multiple times for function at the factory so if you immediately have problems out of the box something has changed. 1st issue we see is lack of lubrication (Rem-Oil) 2nd issue ammo (Superformance/reloads) 3rd have you changed anything on the rifle? Our Panther Claw is specifically designed for MSR's and using any light (Rem-Oil) oil is not advised. During break-in we recommend generously lubricating the rifle. |

I'll try changing the lube I use( I just used rem oil cause it was all I had but I did use a shit load of it) I never used reloads...don't even own reloading equipment (yet)..all factory ammo...the superformance was used just cause I had it laying around as well Only thing I've changed was the stock ( factory stock didn't fit me at all) What's your thoughts on the chamber being super rough? I've never seen a chamber that rough before even on surplus guns. Thanks Brent |

Have both a GII Hunter and AP4 in-bound, but haven't shot them yet. I did recently get a GII SASS, however. When I got the SASS, I noticed the entire bolt and chamber were heavily coated in a cosmoline-like grease, more so than any of the couple dozen ARs I've bought in the past. This was a very heavy and sticky grease that would certainly impede cycling. Not sure if yours was shipped that way. If so, Step one is to get that stuff off the BCG, and out of the chamber, replacing it with something slick.
AR-10s like to be shot even wetter than AR-15s. I don't have enough time with my new GII(s) to verfify that's the case, but suspect it still is. Regarding oils, my stand-by for 308 ARs has always been Mobile 1. |

Roughly 100 rounds out of a GII, no failures except from out of spec ammo, and those were a couple of FTF's as the bolt wasn't completely forward. Not the guns fault in any way.
Gun came pretty wet with oil, did not need further lubrication to ensure smooth operation. I personally think DPMS is playing it safe by saying they need to be pretty wet with oil initially. |

I put a magpul PRS on it...(needed a lil cheek well to get a proper view thru a scope) never touched the buffer or spring...just slid the stock on the factory buffer tube and was done Nope never cycled from the get go...put about 20-30 rds thru it with the factory stock and it still did the same thing |

The Hornady Superformance is not really semi ammo. It is to eek out the best from a bolt gun's accuracy. |

Rotating the gas block 1/8" when it's held in place with set screws would be a horrible idea, IF the set screws are already lined up with the dimples.
Take a look at the picture: http://s4.photobucket.com/user/astross89/media/g2barrel1.jpg.html What's going to hold the gas block in place if it's rotated 1/8"? Perhaps loosening it up and re-seating the block might get ports that are very close but not quite right to where they need to be, but I'd be willing to bet you can tell if the set screws are lined up with the dimples based on how deep the set screws are in the gas block. The video isn't very clear in this respect, but as best I can tell, the set screws are fully seated, which leads me to believe they are lined up with the dimples. With the set screws, either it will be lined up with the dimples, or it won't. |

OK sorry for the long time between updates...busy as hell with work...ok i lubed everything well with straight 30 weight motor oil...she runs like a dream now for sure( lesson learned with the light oil). My question now is a suggested weight/type of oil to run in it for winter...gonna try and do some yote hunting between work. Thanks for the previous advise and look forward to more advise about the winter weight oil. |

That's why if I get a GII I wont even shoot it until I swap out the gas block for a vltor/dd/etc quality clamp-on gas block - after carefully measuring and verifying and marking before re-assy to assure barrel gas port to block gas port concentricity. |
