| Hello everyone. I took my AR-15 out today for the first time to shoot well as I started to shoot it would NOT eject the empty shell from the carrier. and I had to manually pull the bolt back to eject and load the next round. I had the gun properly lubbed and everything. My buddy took the carrier apart and said the bolt carrier was too tight in the bolt and the two ring grooves should not be lined up. so we moved the rings around and put it back and it jammed really good to the point I had to tear it down slip a rod down the barrel to get the empty out. Any ideas? I am a newbie and this is my first build. Thanks |

Sorry about that. This is my first build.
It is a .223 gun and I was using .223 cheap ass wolf ammo. I had a magazine in it and had 30 rounds loaded in it which someone told me was way to much. It is a CMMG lower with a colt 1/7 twist upper non chrome bolt and carrier. |

This definately sounds like a gas issue. Check to see if the gas block/front sight is loose. Check to make sure the tube is in the right spot and the pin is still in it. Check the carrier key and make sure its tight. Do you have any pictures? ETA: it doesn't matter if the gas rings are aligned, the rifle will run on just one ring, and maybe even no rings. |

Oh so I can take these rings off and fire the gun? I may need to clean the gas tube as the upper was used I never cleaned it and dont know what my be in it. Most will say that staggering the gas rings is unecessary although I find that I stagger them just out of habit when re assembling the bolt. I wouldn't advise running the gun without any gas rings at all, but yes, I have taken them completely off the bolt and ran a mag through the gun just to see for myself. Do what is suggested above, check the gas tube alignment and gas block for possible problems. |

your buddy is misinformed. on the rings and magazine capacity. 30 rounds magazine holds 30 rounds, some choose to download one or two, but that is for reload under stress.
Check for a plugged gas port, but don't stick any thing down the gas tube Clean the Chamber If it is a used rifle maybe the old owner shot a bunch of lacquered Wolf out of it. |

You need to be a little clearer as to what you're experiencing. If you fire the weapon and it doesn't eject the spent case but you can pull the charging handle back and eject the round manually that "might' be an indication of gas issues. At first you seem to indicate that however later in your post you say you jammed it up good. Does that mean you couldn't pull the charging handle back and eject the rounds? And/or did the round come out easily once you poked it out?
If the later is the case and your rounds are getting stuck in the chamber then a "gas" problem might not be your problem. If your rounds are getting stuck in the chamber you might see torn brass from the extractor slipping off. There should be "3" ring grooves on the gas rings not "2". There are usually three rings on the bolt. As was mentioned however it should work with just one ring. Your friend said the "bolt carrier was too tight in the bolt!" The bolt goes in the carrier!! The carrier goes in the upper receiver. 
If you're new don't fret, we'll get to the bottom of this. |

Okay actually I checked my barrel it says 5.56 which I guess means it can shoot both .223 or 5.56
Now for the carrier http://i64.photobucket.com/albums/h200/1QWK96GT/Picture010.jpg?t=1289089101 And this guy my buddy said should just "fall into the bore" he said his military issued ones just fell in and were not tight mine is "kinda" tight But this is also all new stuff http://i64.photobucket.com/albums/h200/1QWK96GT/Picture011.jpg?t=1289089167 Again I was firing cheap ass wolf ammo. What is this lacquered ammo you were speaking of? |
| Keep in mind that military issues probably have several thousand rounds through them at least. Yes, you can fire 5.56 and .223, and although I'm not a big fan of Wolf I wouldn't be too hasty on blaming the ammo just yet. The laquered ammo has a green tint to the casing with a red sealer around the bullet. If the casing is grey then it's polymer coated. As stated already, check the gas system...go from there. |

Now for the pics I snapped some pictures of my gas tube http://i64.photobucket.com/albums/h200/1QWK96GT/Picture008.jpg?t=1289089166 http://i64.photobucket.com/albums/h200/1QWK96GT/Picture001.jpg?t=1289089166 http://i64.photobucket.com/albums/h200/1QWK96GT/Picture008.jpg?t=1289089166 Now for the carrier http://i64.photobucket.com/albums/h200/1QWK96GT/Picture010.jpg?t=1289089101 And this guy my buddy said should just "fall into the bore" he said his military issued ones just fell in and were not tight mine is "kinda" tight But this is also all new stuff http://i64.photobucket.com/albums/h200/1QWK96GT/Picture011.jpg?t=1289089167 Again I was firing cheap ass wolf ammo. What is this lacquered ammo you were speaking of? The bore is the thing that boolit travels thru. What you are referring to is the bolt carrier, and the bolt should fit snugly inside of it. If the bolt just "fell in" to the carrier, then the gas rings should be replaced. The best advice I can give you is to stop taking advice from your buddy. |

Try some brass case ammo. While there are a good number of rifles out there that work fine with Wolf, I have seen rifles that do exactly as you describe with Wolf. Some break in and will function the stuff later, others never will. If a rifle won't properly function wolf then there is something wrong with the rifle. However, for break in purposes, I would shoot something with a little more power. |

Another thing I noticed is when I went to insert a magazine I had to push pretty hard or slam it to get it to stay in the gun. some of the other ar-15's I have shot they seem to just slide in with ease and clip. Inserting a full mag against a closed bolt is usually harder. Lock the carrier back and try it and see if it goes in easier. |

I have suffered through the same problem as the OP. Wolf and Tula steel case ammo would stick in the chamber and not extract when fired while brass cased ammo functioned well. This will sometimes happen with a tight chamber or one with some rough tooling marks. I cleaned the chamber very well with a chamber brush on a cordless drill and CLP for 5 to 10 minutes to ensure it was clean (This also starts to remove any surface roughness on the chamber walls). I then ran only brass ammo in it for 10 mags (300 rounds) cleaning the chamber as described after every other mag (60 rounds). Then I would start trying the steel cased ammo to see if there was still a problem. One gun ran steel fine from that point and another took 6 more mags before it cleared up. One of my builds for accuracy has such a tight chamber that it will probably never reliably feed steel cased ammo. I have to lock the bolt back and tap every spent steel casing out of the gun.
If the chamber is rough (or dirty) the steel cases will stick before brass ones will as the brass is softer than the steel and will slide easier. As the surface finish in the chamber gets smoother there is less grip of the case on the chamber wall than in a rougher one. The steel casing is not as pliable as the brass and does not deform as much at the same pressure level. This means the steel case does not seal the chamber in the neck area as well as the brass does. This allows more combustion residue (carbon) to build up in the chamber from the shoulder to the rim. To prove this to yourself measure with a precision caliper or micrometer the neck diameter before and after firing to see which one grows the most - brass does for me. Just my $0.02

| Another thing that happened was we had 3 ar15's at the range today mine (never been fired until today), a neighbors he let us borrow(also first time ever shot), then my father in laws(shot many times almost always flawlessly). Anyway all three of them jammed today but mine was the only one not ejecting the shells. I wanna try some brass like you are talking about and see. |
