Well if anyone can figure out how someone who bought a 6.75” barrel before they made the F03 piston can snag one, let me know.
In the meantime it looks like the F01 should have been fine with my higher backpressure Hyperion. Next step will be clean/lube the gun really well and try a different brand of ammo to see if I can get it running. If none of that works I’ll try a different can and if all else fails ill throw the 9” barrel at the problem. Gun ran just fine unsuppressed with supers. Amazing how adding a can throws a wrench into the works. |

Correct, that is a legacy barrel, not a virtus. And very very few of those went out if any as most were canceled and sent 11.5in barrels instead. @coregon can correct or confirm that. I had one of these on order the day that SKU became a thing in 2015 and never got it so I have to make my own lol |

Its a catch-22 - people get frustrated because they invested in a platform, but cant get replacement parts...we don't sell the parts for that EOL product because we have to protect the warranty for that very same customer. Frustrating, I know. |

Bolt carrier parts , firing pin, gas system, hand guard…
I’m glad to see that barrel and bgc are backwards compatible. I think Sig is the most innovative company out there but it comes at customer’s expense. In some cases products are not well thought through, leading to numerous recall. Just about every product released has been recalled. Hell even automotive companies are mandated by law to have replacement parts available for 10 years after end of the production. |

Wish I wasnt so busy the next few weeks so I could get back to the range with a clean gun and different ammo and report back with something useful to the thread. I used my MCX in a run and gun a few weeks ago and havent cleaned it in a bit. Wondering if I can get the Hyperion and GA playing nice on a gun that is actually cleaned and lubed. |

The only unqiue thing to the Virtus and legacy are the handguard. You can still obtain the Virtus handguard from SIG directly and there are at least two aftermarket sources for the Legacy as well as an aftermarket for the Virtus. All the guts of the MCX are capable of being replaced with the most up do date model (Spear LT). They seem to be doing a rather shitty job at "planned obsolescence". It sucks about the 556 but willing to bet they'll still have parts to fix up your rifles but you'll need to send it in. Comparing the 556 to the MCX is rather humorous though, being the 556 was a catastrophe of sales and reception. Do believe it was posted here that the first year of MCX sales outpaced the 556 rifles life. Rather puts things into perspective. The MCX is here to stay, it's the most adopted/utilized modern rifle outside of the AR15 in the Western world. |

The MCX is here to stay, it's the most adopted/utilized modern rifle outside of the AR15 in the Western world. The uppers are unique across all three generations. I have, however (and contrary to Sig’s stance), seen multiple people drop the LT handguard onto the Virtus upper with no issues, you just can’t use the two retention screws. I believe the LT upper will prove to be largely cross compatible with the Virtus upper. I suspect the transition from the Virtus to Spear LT is a more significant progression in terms of performance (mil spec triggers, handguard zero retention, fully ambidextrous, lighter) than the Gen 1 MCX to Virtus, but with far more parts cross compatibility. |

If one were to truly unpack the MCX it does not really bring any new innovative designs another than picktany folding stock interface. It is largely a hybrid of ar15 and ar180 designs from the past. It is very cleverly incorporated together.
1. Upper Bolt bolt carrier-it is simply AR15 carrier cut in half with Ar180 recoil system Bolt-origianl was just an Ar15 but later changed to tapered lug (KAC) Barrel-removable, just like LMT, SCAR, XCR, ACR many other designs Short stroke piston-again AR180, LWRCi, LMT, HK Handguard-unique but follow overall industry trend 2. Lower Mostly standard AR design with the exception of the pickitany interface One can pin AR lower to MCX upper, backwards compatibility AR15 ergonomic are almost impossible to improve All these features are very nicely re-engineered together into very robust platform. Not taking anything away from Sig. It took a lot of effort and money to make it happen. I do believe overall program is very successful. Thanks |

Facts remain though, if a legacy mcx user shoots out their barrel, they can swap out to a Virtus barrel or soon enough the Spear LT and move on. To be "planned obsolescence", the rifle would be deadlined upon suffering the barrel crapping out and you wouldn't be able to source parts. I genuinely understand your frustration with the 556, as well as the gen 1 MPX owners but the MCX is an entirely different beast and is genuinely supported by SIG. |

Not try to argue that MCX is a bad design but frankly getting tired of sig designing obsolescence in their product. Forward design isn't "planned obsolescence". They build a gun platform about a decade ago. They did as much testing as possible on it in house. Over time, refinements based on contract requirements, further testing, evolving market trends mean constant revision abs refinement. Everyone comparing the 556 to the MCX is understandable, but off base. On the second year or production, SIG had already sold more MCX than in 12 years of 556 production. The 556 was a hobby gun built to a price point for consumers. The MCX was developed in response to a JSOC contract. It's been adopted across USSOF (both SOCOM and JSOC) to replace the HK416, MP7, and MK18. It's been adopted in significant numbers by Allied SOF (UKSF, Ukraine SOF, etc...) and LE/CT units. The MCX is here, and while it will constantly evolve, it's not going to be dropped. If you want an AR standard of standardization, you need an AR. This is a new, constantly evolving, platform that has a long future already steady of it. It's pretty cool that it still maintains decent parts compatibility between generations; major sub assemblies are able to used. |

I have a legacy upper with a 9.5in 556 barrel which took some custom valving for gas and a titanium piston to make it run like a sewing machine. It was a thing. I'd like to get one of those instead of chopping a legacy barrel since it think that has a short enough gas system to run it. But I have no clue on reliablity at that point. https://www.midwestgunworks.com/page/mgwi/prod/calx-mcx-9b-556 |

It’s not a MI handguard but mine is 9” with 10” SIG SD handguard. First pic is with Warden attached and second is without -
With Warden  Without Warden  Maybe close enough? |

Got a question for the experts in here. Will a Sig Match Duo MCX trigger work with the “G” marked carrier latch?
I am trying to complete a mutt of an MCX build and got the last part secured today. Ordered a MCX carrier assembly from here (4 more left in stock as of this post.) I noticed that’s the “Geissele” specific assembly but I already have the match duo in my lower. Will the duo work with that “G” carrier or do I need to swap it out? Will any mil spec AR trigger work with the “G” latch? |

I have about 7-8k round through my 9in cut legacy barrel and it still goes like a champ |

Quote HistoryOriginally Posted By nate_the_great: Now that you mention it, it's a legacy judging by the piston adjustment valve did you have to make any changes to the gas port? have you been running it suppressed? Yes, the gas port was opened up and made a custom titanium piston for it to get it to run like it does now. its been 6ish years and through a few very high round count classes, usually wearing a surefire 556mini with no issues. It was done as project to see how short a 16in legacy barrel could be cut before causing issues due to dwell time (running both suppress and unsuppressed) 10.5 is what I would recommend for most. |

Quote HistoryOriginally Posted By SMFdarkangel: All the new 6.75" exchange kits and TACOPS ship with both. The F01 is intended for high pressure cans. F03 is for low backpressure cans. Not all, my 6.75" SBR came with both, although the F03 was not assembled properly and was missing the roll pin that holds the knob to the valve, but my spare 6.75" barrel only came with the F03. |

Its a catch-22 - people get frustrated because they invested in a platform, but cant get replacement parts...we don't sell the parts for that EOL product because we have to protect the warranty for that very same customer. Frustrating, I know. It's terrible that guns that were produced in 2022 are already considered "end of life products" by a manufacturer. |

The 556Xi was not built in 2022. 556xi was discontinued like 7 years ago. Also, any product that gets discontinued will have a year where it was still being manufactured and is still end of life. |
