I don’t work there anymore but between two county agencies fielding several hundred, they performed well. No catastrophic failures and they proved to be reliable. I had a little over 7k through mine when I left and I only experienced 1 malfunction which I attribute to a worn magazine and not the rifle itself.
There are some drawbacks that I found. The biggest issue was with rail mounted IR lasers. The rail has what I find to be an unacceptable amount of flex. A shift of 2-3 inches at 25 yards is fairly easy to induce with relatively minimal pressure on the rail. This can be overcome some by mounting the laser more towards the receiver but it’s not ideal. They’re also heavier than a typical DI AR.
Thanks, I’ve heard about the rail being too light to hold zero with lasers. Apparently the rail supplied with the M 13 SURG kits is stiffer but of course sake doesn’t seem to sell it to the public.
Given the extra weight of a piston system I can understand Seguin wanting to make the lighter rail the default sense there are Few people actually running lasers, But it would be nice to have the option for those that do.
What length barrel were y’all running?
Did y’all have any accuracy issues ?
I understand some of the early MCX had a very light barrel profile and the longer barrels such as the 16 inch and 14.5 inch had some accuracy issues. Supposedly this was addressed with a slightly heavier barrel profile.
You’re not wrong. I’ve found a few boxes of fed hammer down for what I consider to be affordable 45-70. I ordered a few boxes of Buffalo bore which I’m sure will be brutal to shoot. And I have 2 boxes or hornady 325s which weren’t awful. I’m just glad I won’t be shooting it a lot because $50 for 20rds on the low end of the spectrum is rough.
You’re thinking a rebarrel instead of a second upper? I’m watching for an 11.5” 5.56 upper to make my Rattler more versatile, and will probably form 1 it. It’s too expensive to travel with it as a pistol anyways, and I’m NY screwed (landlocked.) I think complete uppers may be easier to find.

From my experience the MCX is the best thing going if you want a piston gun on an Ar15 lower.
