I remember a few people complaining of excessive wear inside the receiver, cam pin scratching/gouging. Mine had this issue and went back to the factory on Thursday. Anyone have a positive result of sending theirs?

Received the MPX today. Gunsmith replaced upper with new receiver. Appears to have the same barrel and does have the same bolt carrier group. Comments on receipt stated "damaged was caused by the bolt carrier arm protruding, at one point must not have been locked in place though it was when I inspected it." Grammar issues aside, not sure if his assessment is the same as my assessment but I'm glad that they replaced the damaged part. New receiver has a very dull and rough finish compared to the original. Just need to reattach all the accessories and get to the range for a zero.

Just thought I'd pop in and drop a picture of my MPX how it's currently set up.
I got the Osprey 45 to fit on it now, so I took some photos.
This one was my favorite.

I haven't shot it suppressed yet, but I will next time I make it out to the desert.

Who makes the carbon fiber hand guard on your set-up?

Well, I guess Sig is going to be focused on the P320 fix for a while, there go my hopes for the 357 upper for the MPX...

I never tried the factory irons with it - I pulled those things off forever ago. I don't like how big and bulky they are.

Sent you an email

I did the same thing with my factory irons, they aren't for me. Since it is just a range toy for me I'm fine with just having a red dot on it.

Yep, lancer.

Can anyone confirm that the Barcelona Spain police on scene and on tv today- if they were carrying MPx's?

After almost a year, I finally received my stamp for my Innovative Arms ported "integral suppressor". Also installed a BFS III as well. Pretty fun time at the range.

Mine has a gouge just like yours. I hate to send it back to the factory since its a sbr.

How long was turn around time on yours?

About 2 weeks, give or take. Mine is an SBR too. SIG customer service told me to remove the stock and all accessories prior to shipping it back. They paid shipping both ways and it runs just fine now.

Was the gun not running correctly, or is the issue just cosmetic? What did they to fix it?

The gun ran fine, only issues were ammo related. I was concerned that the amount of wear it showed at 1000 rounds would just keep getting worse. And since they offered to fix it under warranty without any out of pocket with shipping, I figured I could do without it for a couple weeks.

what did they do? it's not like they can just give you a new lower cuz of the sbr paperwork.

I feel like a total idiot...

I just assumed it was the lower for whatever reason.

I've never seen an MPX in a movie or TV show until an episode of Bosch. Other than this being one of my favorite all-time cop shows, it was neato to see an MPX being used. I think it was even referred to by name in the episode other than just being used or brandished.

Saw the MPX in Logan and Bright. IMFDB also listed the MPX in Baby Driver.

The MPX is also in a couple video games now.

Butt stock question here. Have a MPX SBR on layaway with the Collapsible stock. I am debating on the folder just for deployment purposes. Any thoughts rel: this. Looking for someone who has already taken that step. Thanks in advance.
