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 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? |

I installed the Wilson Combat TTU MIL/LE trigger and I am very happy with it.

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. |

Rock River has NM triggers for about 65 bucks. I installed it. Excellent trigger.
|

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 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 hard 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. View Quote Thanks for the video Tim, they are great. Check your email. |

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.
