Mags will fit in either generation, but may experience higher failure rates if you don't use the corresponding gen mag/upper. 10rd and 20rd mags were intentionally held back until 30rd mags were 100%, so they should be flowing soon. |

Can you shed some light on this issues. Are we talking frequent mag failures or maybe just less than 100% on full auto or something like this? Are Gen II uppers compatible with Gen I barrels/bolts? i have so many questions and have seen about 5 different answers people have gotten from Sig. |

Coregon,
Thanks for the info on the magazine issue. Needless to say this is very disappointing to hear. I now have a good supply of Gen 1 mags that I expected to use for a Gen 2 PDW along with my Gen 1s. That will not be happening now. Most of us understood that a new Gen 2 upper would be needed for caliber conversions. Never was there any mention of new magazines. Do you know if 10 rd and 20 rd magazines will be manufactured for Gen 1 uppers? To make this right Sig should swap out the Gen 1 magazines for Gen 1 customers that purchase Gen 2 uppers. Thanks |

Just figured out that my Octane 9HD was already set up for 13.5x1 LH (albeit with a piston and spring). What is the best way to run the can... Fixed mount or piston w/ a spacer? I figure a fixed mount will take up less internal volume and thus be a tad bit more quiet, but I'd like to get the opinion of those with more experience on the matter.

Just saw this on the mpx Facebook group
"I talked to Sig earlier. I found out that the mags that came with our MPX (Gen 1) and mags we are buying now will not work in Gen 2 models... Did all of you know that? He also confirmed that the caliber conversions/barrels would not work with our Gen 1s which most of us already knew. On a brighter note, when things start flowing, he said that Sig will offer Gen 1 owners a Gen 2 upper for the price of a barrel conversion (1 time deal). For the most part our Gen 1s will now be Gen 2s and accept all barrel conversions. Just remember that any magazines we are using now will not work/feed in our MPX after the new upper is installed. Might not want to buy to many "Gen 1mags" if you plan on eventually upgrading to a gen 2 upper. Some or most of you might already know all this. I didn't..." Pretty interesting. |

Just to make sure I understand this correctly... Gen1 and Gen2 are only referring to the uppers correct? The lowers have not changed? And the lower is the actual "gun"? So, if you form 1 your MPX, you will be able to swap out to Gen2 uppers and be fine, except if you are using Gen1 mags? Geesh!! This is getting confusing!

This company can't deliver a few hundred fucking stocks. And they're going to manage the production logistics and timely/adequate supply of all this extra stuff, in multiple generations? |

You really need to wonder what's going on over at Sig management that would tell the public they are releasing a multi-cal firearm with easy change barrels, than release something other than what was promised, and not only that follow up with a gen II version that may or may not have mags that are compatible with the gen 1 version. I do not see how heads are not rolling over this. |

So I have been playing around with the cheek weld on my Shockwave/KAK and T1/LT660 mount. To be honest, lower 1/3 AR-height co-witness feels too high. For those of you with T1/T2/Holosun/PA Advanced RDS's, what do you think is the ideal mount height should be? Absolute AR-height or maybe a low mount (ditching the SIG BUIS altogether)?
Btw... I'm not a fan of the included BUIS. Maybe it is just my eyes, but the larger aperture is far too large and thin. The small one is fuzzy as well. I wish Magpul made MBUS Pro Micros. |

You could always drill the smaller aperture out to something that works for you. That would make it just as bad as the large aperture (to me). When I get behind a LMT (fixed), Larue (fixed), MaTech, ARMS, KAC, MBUS Pro or even (heaven forbid) a Troy, I see a defined circle that I can align a front sight within. On the Sig I get, so fuzzy I can't even make it out (large aperture) and a little less fuzzy but still slow to align the HK style circular front sight within. I thought it probably had something to do with the shorter sight radius but I double checked using MBUS Pros mounted on one of my SBRs that has a 7" rail and I could quickly and easily pick up a good sight picture using those irons. |

Whats the deal with 16 inch carbine, does it have a removable FH, is it threaded with the 13.1 X1 taper? I cant tell from the pictures. I am tempted to get one to be companion to my SBR so I could get a tele stock and a GEN II upper at the same time.

Just got done with the MPX's first range trip. Running 147 gr. Subsonic along with an Octane 9HD.
Takeaways: - Awful trigger. The worst I have ever pulled on an AR type platform. - Great ergonomics. It really feels good in the hands and it ponts/moves almost naturally. - Superb accuracy. Right out of the box, I was stacking holes at 15, 20 and 25 yards. - Recoil is very manageable both suppressed and unsuppressed. It stays on target during strings of fire. - I hate the irons (aperture too large for me) - 3 out of 5 mags did not LRBHO. This was all using the same mag. - Very gassy. This is the most crap I have ever had blown directly to my face. This is alarmingly close to a deal-breaker. - Very fun to shoot. Something about the whole package just feels right. Granted, some of the issues could be attributed to the ammo, but still, due to the whole back end/charging handle design, the MPX pretty much has gas going directly to the shooter's face. I'd like to see someone make a gas deflector charging handle for this thing. I hear the Evo 3 has much better gas management so I'm going to pick one up and keep the one that is less irritating. |

What 147gr ammo ? I just picked up 1000rds of the Speer Lawman 147gr but haven't shot it yet. I also hate the giant Iron Sights they put on this gun too. Also though my AAC TiRant 45 had zero gas face issues. |

Just got done with the MPX's first range trip. Running 147 gr. Subsonic along with an Octane 9HD. Takeaways: - Awful trigger. The worst I have ever pulled on an AR type platform. - Great ergonomics. It really feels good in the hands and it ponts/moves almost naturally. - Superb accuracy. Right out of the box, I was stacking holes at 15, 20 and 25 yards. - Recoil is very manageable both suppressed and unsuppressed. It stays on target during strings of fire. - I hate the irons (aperture too large for me) - 3 out of 5 mags did not LRBHO. This was all using the same mag. - Very gassy. This is the most crap I have ever had blown directly to my face. This is alarmingly close to a deal-breaker. - Very fun to shoot. Something about the whole package just feels right. Granted, some of the issues could be attributed to the ammo, but still, due to the whole back end/charging handle design, the MPX pretty much has gas going directly to the shooter's face. I'd like to see someone make a gas deflector charging handle for this thing. I hear the Evo 3 has much better gas management so I'm going to pick one up and keep the one that is less irritating.

So, for someone jumping into this thread late, what's the story with changing calibers in the MPX2.0? full upper swap or just a barrel mag change as originally designed?
Seems like MPX1.0 owners will have to swap uppers and mags won't be compatible? ETA: just found the other thread. Apologies. |

MPX mags in stock at Top Gun Supply. $62 and about 190 in stock. No neckbearding. Link

Due to lack of confidence in the HK Parts design and TROS' logistical challenges with delivering product to customers in a timely manner, I ordered a Griffin Armament 3 lug adapter for my Octane 9 HD (w/ 3-Lug Mount).
The Griffin 3 lug adapter looks well made and upon closer inspection, appears to have addressed the issue with the MPX's taper nearing the muzzle. It looks like the bearing surface is against the muzzle end (as it should be for this application).     I'll follow up with thoughts on how well it mates with the Silencerco 3-Lug Adapter and whether contact is made against the Sig's muzzle end when tightened later this evening. |

It will contact the muzzle face of the MPX barrel, and will also work with other market offered 3 Lug mounts.

I heard it will work and offers a shortened length when compared to the Silencerco 3 lug mount. Anyone use this on the Octane suppressors? I'm hoping it will be ok. |

That looks really good - and has wrench flats that the TROS 3-lug adapter does not have. Looks like GA is the go-to for MPX 3-lug adapters. |

Did you do the comparison between the HK Parts and TROS muzzle devices? If so, thanks for the contribution. It was the basis for me deciding to try out the GA part. |

Also good to know that the GA part is made out of 17-4. I'd love to get one of GA's, but I've already blown a load of cash on M13.5x1LH 3-lug adapters.  |
