What do you recommend bare minimum to have on stand by. Also where can u find?

Hello everyone, I’m looking to replace the original flash hider on my MPX copperhead midnight edition with an ASR flashhider for suppressor use and am having problems doing it. I put my upper in my “no mar” AR upper receiver vise and after putting what I thought was quite a bit of pressure with...

Not sure if this is the right forum, so please forgive me if it's not. Does anyone have experience using the Leupold Freedom RDS red dot on their MPX? I currently have a Romeo 4S with the Juliet magnifier. Someone mentioned that I would eventually drop the Juliet, and now it seem a bit...

Ok I have some really nice guns. Some historically significant pieces and some really fun stuff. I haven't been this excited about a new gun in a while. This wasn't even on my radar as a want or need. Just a cool gun that I wish I had when I lived a more dangerous life. Given current events I...

I picked up another sig mpx k today and I am a bit confused. It is the fde mpx k and it has the m lok handguard but it doesnt have the timney trigger. It was said to be bought in November 2019 from modern sportsman. I know sig doesn't officially have a gen 1-3 but what is the best way to tell if...

I just got a sig mpx gen 2 with the mlok handguard and have a silencer co asr flash hider for it I noticed the barrel has a tapper so do I need a taper adapter part to install the asr flash hider?

I'd like to move my MPX-K to my bedside for home defense. I have a 320rx now in a little Vaultek tucked neatly in a sliding nightstand drawer. My constraints are: Wife doesn't want a big ugly safe in the room (think pottery barn magazine for bedroom layout) I have 6 year old son that is a...

I have a sig mpx gen 2 4.5" from 7/29/19 and I was wondering how can I tell I have the most updated parts for reliablity? I've seen so many changes between it and the newer "gen 3" with m lok.

So I've put on a Sig Romeo5 red dot, a TLR 7 white lights, and the smallest green laser I could find which happens to be made by TruGlo. But....the laser block at least 1/3 of the light throw. Should I put a riser on the red dot, then the TLR 7 too, or just accept some light blockage in the name...

Hi guys, I just got myself an MPX K with a folding brace. I want to get a backpack for it. Apparently all the Sig made backpacks are sold out everywhere. Can you guys recommend me a backpack? Something not too big. just something to take to the range and back. Thanks!

Does anyone know if an SRD9 will fit inside the handguard of an MPX PCC? I have the mpx pcc and I want to sbr it, get a shorter barrel and run an SRD9 suppressor under the standard m-lok handguard but I’m not sure if it’ll fit. The diameter of SRD9 says 1.38” and measuring the inside of the...

Howdy Folks, new Sig Owner here ... happy about that :D. California resident ... sad about that :( So I have to do a fixed mag on my new Copperhead. I purchase a fixed magazine from bulletbutton.com: https://www.bulletbutton.com/product-p/mpxpmr.htm White they were responsive and confirmed...

I picked up a used mpx gen 2 and it looks like it has the updated firing pin with the groves in it and I hope new bolt to match but dont know how to verify that. I saw someone mention that they changed the Tappet/gas valve is that true? If so how can I make sure mine is up to date on the rolling...

I'm thinking of put a Trijicon MRO on a MPX and I'm considering LaRue Tactical mounts. There are two options, LT839 and LT849, both are described as 1/3 cowitness with the iron sights on M4 carbine and AR-15 flattops. The only difference I see is that one is cantilevered forward. I'm not sure...

I'm looking for a bit of advice before making a purchase. I own a Sig MPX with both the 4.5" and 8" barrels. Both of those barrels are threaded in 13.5x1LH thread. I have selected the Dead Air Wolf 9SD (https://deadairsilencers.com/products/wolf-9sd/) to be the can that I will mount onto the...

Hi there, I have an MPX with the 8 inch barrel. I just traded some guy for a 4.5 inch barrel. The problem I’m having is that the barrel seems to be different because my flash hider doesn’t fit on this barrel and it has this backing plate behind the threads. And the threads seem to be too low...

OK MPX buddies ... I need some advice. I'm swapping out my 4-inch barrel for a 6-inch barrel to accommodate my suppressor. Needed just a little more barrel protruding out from the hand guard. I got the screws out just fine, but that little bar on the other side that holds the screw's female...

Anybody out there use this combination? The piston "bottoms out" at the end of the threads. I tighten it and then adjust with the rotation lever. It "looks" and "feels" OK, but this can doesn't bottom out at the end of the barrel threads on my P226 or P229 (same threads as a MPX). I'm...

Hello fellow Sig owners! I'm new to this forum, but not new to Sig. I have an MPX with all three barrel options, and love it. The reason for my post is to share my experience with the Franklin Armory Binary Firing System trigger, and follow up experience in dealing with the customer service...

I'm a Sig man for 30 years but have only had my MPX (Gen 2) for the past 2 years. When I got an AAC Ty-Rant for my rig I started experimenting with sub-sonic rounds. I've tried all 6 of the 'major brands' and conclude that Emcon 147 gr. TMJ is the most reliable - BUT, it will also give me a FTF...
