Put 920 rounds through it today. Ran really great! Only had 3 failure to lock back. One on a pmag and two on a usgi magazine.
Other than that I got the irons zeroed up in 9 rounds. Put my EoTech XPS on and had no issues zeroing that as well. The recoil impulse is pleasant, I think it could still benefit from a brake or can. Cheek weld took a little getting used to, I've never used a stock this skinny. I got used to it by the end of the trip. I was able to run the 1-5 drill in about 3.25sec several times. Transitioning from target to target was smooth, but the thin cheek weld was weird while I was doing it. The handguards got a little warm but never uncomfortably so. I did a 6 30rd mag dump and at the end of the 6th mag it felt like it was slowing down/getting gummed up but it still functioned and locked back. Overall really impressed! Can't wait to run it through the rifle course on Monday. |

I have to tell you, the more I fire this thing, the more I love it. It stays so clean compared to the DI weapons. Almost makes me want to get rid of the DI guns and just have a few of these.
Are all gas piston rifles like this? Amazing. |

As far as cleanliness/fowling, piston systems reign supreme. |

Seems like my mcx is always filthy after a range trip. This was the first outing with maybe 200 rounds. The inside is way worse. It got so dirty it was oozing out of everywhere. Suppressed problems.

Suppressed setting, with either clp or 30wt motor oil
I havent seen a platform that is actually blowback free. My pvs14 was covered in carbon. We were shooting @250-300yd, nighttime at about 50 degrees. I had the 14 mounted behind the t1. |

Anyone have a Geissele installed on their lower?
Just put an SSA in mine yesterday and I noticed the pins aren't flush with the receiver - is that fine? |

Thanks, they aren't too short but it isn't flush with the receiver face like on my AR-15. I think that the walls are thicker on the MCX. I wasn't quite sure if I wanted to replace my trigger in the first place. It was coming at 5.6 lbs and with only a very, very small amount of creep. |

Just dropped a Geissele SD3G trigger in my MCX. Gonna be tight. Trigger pull is terrifyingly short and light. Can't wait to get to the range with it. Sorta need an optic now. I'm pretty happy with the iron sights right now.

I'm pretty happy with the iron sights right now. I have been debating keeping irons versus going with an optic. I am much faster with my Red Dot than Irons, but like the feel of the irons only on the MCX. I guess I like it as a challenge. |

I view it as good practice. It's important to be competent with irons. At the same time, I know I can bring this rifle to its full potential with some optics.

How tight is yalls upper to lower fit?
The one I looked at had a little slop, so it was about like most ARs. I thought the MCX had a spring built in to tighten the fit? |

I like it. I like the things I'm reading about it and the videos I've seen......but......
I'm afraid to get one. With Sigs recent history with the 556 and the 556xi, how long is this one going to last? Another is the proprietary parts. I like having extra parts available. Are there any sources other than Sig? |

I really like the MCX, but that video was not very assuring. That mud/water wasn't even that bad and for the MCX to run so poorly was unacceptable. We may not shoot it in those conditions, but others will. My M4 has been shot after dropping into a mud puddle, and no issues.

In all honesty, I like the MCX. I think, given what I've seen other guns do over the years here in my AO, it did ok. I say that in the video. What I like is that with a rag and a few minutes I was able to get the gun back into 100% service just by wiping it down a bit. It does bother me that not much gunk got into the gun at all and it still had issues, but I do think it's most likely hydro-locking. Once the water is gone it works. I don't think rain would cause this issue, it would require a full dunking.
Overall I like the MCX quite a bit, far more than I thought I would. I hate the taper mount Sig put on there. I've not been able to successfully suppress it. Sig isn't selling the necessary adaptor to mount a non-Sig suppressor yet, I've not been able to get one anyway. I am not buying a Sig suppressor just for the gun. Aside from the taper mount shenanigans the gun is really quite interesting, accurate (just over 1" with 77 OTM), light, handy and very shootable. I don't like the complexity of the internals, it's more difficult to break down than an AR but the trade off is a wider variety of stock options if Sig ever decides to release them for sale. Would I replace my favorite BCM with the MCX? Probably not. But will I sell my MCX? Nope, I like it.  |

Tim, thanks for chiming in. HOnestly one thing that stuck out to me that didn't before was the recesses of where the springs go into the upper receiver and how hard that is to access and clean. A bore brush of some sort would probably be the best bet, I guess. Again, thanks for chiming in.

MAC, I noticed in one of your earlier MPX videos you mentioned the two barrel bolts had backed out. Any such issues with the MCX so far? I wonder if SIG would recommend using Loctite on them? And if so, which kind? Yes you can use loctite on them. Use blue Thanks for the input. Will the heat from the barrel under fire cause the blue loctite to fail? I've used it on screws for things like stocks and scope rings in the past, but wasn't sure about high temps areas on a gun. Originally on my first MPX there was no locktite on the screws. One loosened a bit and opened the accuracy up a little. Once I applied blue locktite, I never had the issue again. My second MPX had blue locktite on them from the factory. I've never had the issue again and my first MPX has close to 4000 rounds through it with no malfunctions and cleaned 3 times |

It's really a non-issue. Once I caught it happening I was a bit surprised, but once I got it back to the shop and locktited it it's not been a problem. I like the MCX and the MPX. As a matter of fact, I just went on vacation with the family and the MPX went with me as my "SHTF" gun in a little get home bag.

Tim, if you had just 2 weapons to chose from an ARX or MCX, what would you pick and why? I actually have both platforms and I like them both very much.

Anyone else's MCX like this under the selector? I thought it was rust and wanted to remove the selector to check the back of it but the tiny hex is stopping me from doing so. Just hoping it's the factory grease or something that caused the discoloration. It was far more orange before and wiped away what I could and it was orange on the rag.
Ok nevermind it was a roll pin lol. So I knocked it out and it was not rust. The selector was outlined from the grease or something - however it is not removable so if you see it don't bother with removing the selector. 
I saw that my selector was wearing the finish off under despite the grease or whatever - I may take it off again tomorrow and replace with my Colt ambi selector to prevent this. Not sure why the selector was designed this way - some offset would've been preferred.

Quote HistoryQuoted:
I hate the taper mount Sig put on there. I've not been able to successfully suppress it. Sig isn't selling the necessary adaptor to mount a non-Sig suppressor yet, I've not been able to get one anyway. I am not buying a Sig suppressor just for the gun. I called Sig and spoke to Jim Hadley in the suppressor division, who mailed me the taper adapter at no charge for use with my suppressor muzzle devices. Supposedly all new rifles ship with one, but that's what I was told before I received my MCX by a Sig rep, and didn't get one in the box. I posted a picture of the adapter earlier in this thread in case you want to see what it looks like. |
