Stay away from the frontier 5.56 M193 though, there are enough lots with pressure issues that I would not risk it. View Quote View All Quotes View All Quotes Originally Posted By homeyclaus:

I haven’t used IMI in the ARX, but I haven’t been happy with the IMI razorcore 77gr. The black hills load and legit mk.262 mod.0 are substantially better. But then again, sample size of 1 and all and I may have just got a wonky lot which does happen from time to time even with big manufacturers.

I use the ones from RobertRTG and they are better suited to the high rail on the ARX. Regular AR height sights are pretty high, but work OK.
The factory sights seem better suited to a "no witness" sight picture with a red dot - using a lower RDS that is below the sight plane when the sights are up and usable when they are folded. |

Any on your know why both of my extractor/ejector assemblies would bend inward and in turn cause the gun to start to burst fire? This is an SBR with factory 10” barrel, AAC Ranger suppressor and Shooting Sight trigger.
I have ordered new extractor/ejector assemblies but really don’t want to install them just to bend them again. I’m guessing it’s off to Beretta for a look but if one of you know something I should be looking at before going to the UPS store I’m all ears. Thanks. |

Are the extractor/ejectors working as needed? Extracting and ejecting?
I am trying to visualize how they'd effect firing a round or rounds instead of the hammer, firing pin, trigger, etc on the ARX trigger group. |

As they are dual purpose, the extractor/ejector unit (x2), if they could somehow perform the same function at the same time then it'd be a different set of problems?
They'd both extract at the same time, so the fired round would extract and not eject or they'd both eject at the same time, not extracting the fired round at all? Don't know if something could muck up the ejection direction selector plate and do that, but that's not what he's describing. |
|
|
This is also where easily giving in to peer pressure and buying another ARX would make it handy to troubleshoot.
I'd have to look at my bolt to see if the ext/ejectors could bend in enough to push forward on the tail of the firing pin? From memory, I'd think they would have to bend inward at almost 90 degrees to do that. |

View Quote Oh and the dual extractors/ejectors both act as extractors at the same time always, which is one of the great things about the ARX. The only thing that is switchable is which one becomes the ejector. To me it kind of sounds like something got messed up on the Shooting Sight trigger installation, but as to why he suspects that it's the extractors/ejectors I have no idea... Though he must be seeing something that leads him to think that. |

I see now as the ext/ejector units both always keep tension pulling from the face of the bolt rearward until one of them is stopped. I wish I could think of stuff like that. View Quote |

I also prefer the safety location to that of an AR for ambidextrous use, because on an AR one of the levers is always kinda in the way of my firing hand... I don't have this issue with the ARX due to it's location. |

Sorry guys, fresh snow today so the powder called.
I can get some pictures up soon. The extractor/ejectors aren’t bent too bad but they did cause the BCG to lock/bind in battery. After pulling the charging handle and slamming the butt to the ground it unlocked. That’s when I broke it down and found them bent. As someone else has suggested in and IM, I need to check to see if the firing pin is stuck. Super strange as this gun has been flawless for years and about 1000+ rounds (not much I know). Then, one day I take it out and the first pull of the trigger it runs a 3-4 round burst. Then another. That’s when I stopped. I’ll get some photos of the extractor/ejector assemblies and check out the firing pin. Thanks. |

I mounted an old Aimpoint Comp ML2 on a low ARMS mount (it's what I had ) and put it on my ARX. The height is perfect.
I sighted it in on an Appleseed target and shot a quick and dirty AQT. It did alright, and I was basically doing it as one long string. But after a quick 30 rounds, the handguard's vent holes were putting out a good amount of smoke. I'm not worried, it was the first time I ever shot that much with it. But my last ten rounds impacted much higher than the rest. I don't know if I was accidentally resting the mag on the ground when I was prone, or if the barrel has a POI change when it gets hot. |

I know I’m late to the party but I decided to order an ARX while they are still available and reasonably priced, I’m excited to try it out.

Do you mind sharing who you ordered from, I wasn't aware any 16" were in stock. Maybe you ordered a SBR ?

Okay here’s some photos showing the bent extractor/ejector assemblies. The left side is worse than the right side. Attached File
Attached File Attached File I don’t feel the firing pin dragging but did notice that there is a dent near the pin channel from the hammer. I need to inspect the lpk/fcg and it’s installation. Attached File If anyone has thoughts I’d love to hear them. Also, for any of you that have had stocking firing pins how did you solve the issue? |

That 7 o'clock area of the rear of the bolt is where the hammer would impact if the hammer was dropping before the bolt was locked? Sound right?
The hammer channel runs 6 to 12 o'clock when the bolt is locked. |

Also, for any of you that have had stocking firing pins how did you solve the issue? View Quote Also, that dent on the back of the bolt indicates that the bolt is not fully locked when the hammer is dropping. Definitely check to make sure that your disconnector is working, maybe the spring is missing or broken? I've also seen someone else with a dent on the firing pin channel on their bolt, I think it was determined that it was happening while the bolt was beginning it's travel rearward and dragging on the first Generation Shooting Sight hammers which didn't have chamfered edges on both sides of the hammer face. However, in your situation with the gun firing bursts makes me think that it's a disconnector problem. I also wonder if the use of the sound suppressor doesn't have something to do with the extractors/ejectors bending. Maybe the impact velocity is just too much for them to handle with the added back pressure from the suppressor? |

I would suspect bending compromised the extractor/ejectors. Perhaps consider replacing them.
BTW, anyone know if there is there anything newsworthy happening at the Beretta SHOT Show 2020 booth? |
