I can't say that my AXR has been the most pleasant of experiences. When it works, it's fantastic, but I cannot recall ever having a trouble-free day at the range.
It has under a thousand rounds through it, and the most common failure right now is an FTE which happens every ten-fifteen rounds if not more often. Bolt cycles, grabs another round, and tries to push it into the shell casing which remained in the chamber. After clearing the magazine and now-very-bent round of ammunition, a simple manual recocking of the bolt, letting it slide forward on its own, will grab the round and the next manual pull back will eject the shell casing no trouble at all. During post-range cleaning last night, I paid particular attention to the bolt face and the extractor, to ensure that there was no obstruction which was preventing the bolt from properly meshing the round or the extractor from closing around the rim. Extractor seems to function well enough, it moves under manual thumb pressure, and I have no reason to believe the extractor spring is weak. Of course, I also don't have the best basis for comparison. I wouldn't be surprised to discover that I have the only AXR in the State, so finding another to compare against side by side is unlikely. "Regular" AUGs aren't exactly common in the San Francisco area either. I'm open to suggestions or thoughts. Thanks NTM |

Upgrade to the new firing pin kit and bolt sleeve usually fixes the problem. Check your firing pin and bolt sleeve, and let us know what you have. Thanks, Pete Athens

| I had the same exact problem with a new MSAR STG , i found that the extractor spring was lacking the O ring . After adding the little O ring the rifle extracted reliably. The O ring gives the extractor more tension to hold onto the case rim. Im not sure if the Steyr uses the O ring but it sure sounds like you have an extraction problem and i would start with a new spring . |

No idea which is the new and which is the old, but this is mine. (I have rifle #78, if that helps). I note the firing pin spring is different (How would that work in the bolt?), and the plastic yokie on the bolt spring. 
If, indeed, new parts are recommended, where do they come from? Steyr's website? NTM |

Steyr's website? NTM By your pics you have the updated bolt sleeve so I would rule that out. Though it seems you have an auto firing pin which that doesn't matter too much. Does your extractor rip the casing or doesn't mark it at all? You might have a weak extractor or your barrel chamber needs polishing. Pete Athens |

Manic,
This is Kent from what is now "TPDUSA". I can help you, I just need some more info. Contact me @ [email protected] Kent |

Kent Luttrell sighting! How are you man? Here's what my AXR is looking like right now, 1.5MOA on Hornady Match 75gr. Still love it!
Manic_Moran, have you run steel cased ammo at all? It's not necessarily bad for the gun, but the coating can build up in the chamber and cause issues with brass-cased ammo. Pull your barrel out of the receiver and visually inspect the chamber. If it looks free of defects, put it back in the receiver, remove the receiver from the stock and then clean the chamber with an AR-15 chamber brush and some CLP. Try shooting it again but stick to brass cased only and always clean your chamber when switching from steel to brass... Also, what is your gas setting? High or low? As others have mentioned the RatWorx Steyr-spec hybrid bolt is probably a great solution. Uses AR-15 extractors, so if you need a bit more extractor tension there are endless AR-15 extractors, springs and bushings you can use to sort the problem out. I've been considering purchasing one for my rifle and using my current bolt as a spare part. If you want to keep the rifle true to its original spec, it uses genuine Steyr parts in the bolt carrier group. All AXR's came with Steyr-mfg auto carriers imported from Austria if memory serves (mine did.) |

What up Kent? Chris |
