  2. M400 Tread Magnifier

    SIG Sauer Rifles
    Wasn't sure whether to post this in rifles or optics but this seemed to have more involvement so I apologize in advance if this is in the wrong spot! Long story short, I purchased a Tread and Sierra3BDX (3x-10x) combo for a decent price. This is my first AR and first rifle in general but I...

    SIG Sauer Rifles
    Hello all, New to the SigTalk but really in need of advice. I recently purchased a M400 AR15. It has Magpul furniture on it and I am in the process of finding a sling. I just don't know what accessory I need to make it fit. I have found one that I think will be suitable: Magpul Industries MS4...

  5. 3rd Sig Purchase, time to join here

    New Member Introductions
    Hello all! Today I bought my 3rd Sig, a P320 RXP Full-Size. Loving the Romeo1Pro that comes with it, however I was disappointed it didn't come co-witnessed to the irons. Currently have plans to convert it to the XFull because it's tough to find guns in stock around here, so just getting the...
  6. M400 Tread - First Cleaning Instruction?

    Guns
    Hey All, I'm new to ARs and guns in general. Whenever I get a new one I like to clean it before I use it. I recently purchased Sig's M400 Tread. Should I just rely on the manual or does someone have a video link they really like. I can look up any video, but wondering if you know of a link you...

    New Member Introductions
    Hey All, I am very new to owning guns. Growing up in the North East it just did not enter my mind, but I'm happily settled in the South/Mid-West now and enjoying it very much. I purchased a couple handguns this last year and then became intrigued with the AR platform. Did some research and...

  9. M400 Picatinny rail, sights, and torque

    SIG Sauer Rifles
    [Question] M400 Picatinny rail, sights, and torque I recently ordered front and rear sights for my SIGM400 Enhanced Patrol 5.56. The M400 came with Magpul polymer flip-ups but I prefer fixed. At any rate, I can’t seem to find much information about torque for sights and the Picatinny rail...
  10. SIG M400 Range Report

    SIG Sauer Rifles
    Took the M400 to the range for the first time today with my shooting buddy, who is former EOD. It's been years since I've shot a rifle, and besides an M-1 a long time ago, nothing above a .22 LR. I had a ton of fun and can't wait to go again. Only shot brass, a little over 100 rounds various...
  11. Just bought my first SIG: M400

    SIG Sauer Rifles
    Getting back into shooting after losing my dad when I was younger. He taught me the basics, mostly with pistols and a Henry .22LR lever-action. I bought a Glock 27 and took my CWL class after the attacks in Paris, and reconnected with one of my mom's coworkers who used to take me shooting. Found...
  12. M400 Classic vs Swat

    SIG Sauer Rifles
    New to guns and new to the forum. I'm looking to pick up an M400. It will probably be my only rifle for some time. I'm mainly looking at it for home defense and shooting at the range enough to become quite proficient. This will not be a major hobby. The only "extras" I could really think of...

    SIG Sauer Rifles
    Just picked up the all black Sig M400 Enhanced at a local store. Decked out with all the magpul stuff for $859.99. Have to say I love the look of this gun, pumped to shoot it here soon.

    New Member Introductions
    Greetings. I recently purchased an M-400 at my local gun shop, I've put about 200rds through it in the last week, but the internals seem like they have a pretty rough finish, almost like unglazed porcelain. Is this common? Can it be fixed?

    Good evening, all. I am in the market for an AR-15. I love the Sig name and own a very nice P227 SAS. I am familiar with the AR and its functions.

  20. M400 and Slidefire

    SIG Sauer Rifles
    Had my M400 for almost a year. A great rifle in every aspect. I bought a new Slide Fire stock. I'd been seeing both good and bad reports on this combo. Some M400s work with the Slide Fire just fine, others, like mine, don't work. Any ideas on how I can make this work? It seems the two sling...
