    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...

    The only thing constant in my collection is change. That’s not entirely true, but I do have an updated set of parts that I’d like to pass along to someone else that might need them more than I do (since they’re just sitting in a box here). Sig MPX Factory ambidextrous charging handle, Gen 2...

    Selling off my 8" Keymod MPX Handguard. I went a little overboard picking up different handguards because of how easy they are to swap out, and I need to pare it back down to a more manageable pile (since I only have one MPX). If you've got a "K" pistol (4.5" barrel), you can fit this over most...

    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 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...

    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...
