Good evening y’all! As we are all more than likely aware, the M400 series of rifles & large format pistols (Tread, Snakebite, Predator, Switchblade) are all outfitted with Sig’s proprietary barrel nut featuring it’s own unique handguard “mounting pattern”. It looks like this: Now, I don’t...

M400 tread offset iron sights I want to add offset iron sights to my m400. I want to add a 3 slot picatinny to the m lok slot not directly on top but the slot directly to the side and mount a front iron sight. The only thing is for the rear iron sight the only picatinny is on top. I could use a...

I'm a newbie to the rifle/AR area... I really like the M400 Tread Coil with the romeo sight, foregrip, etc. But I'm undecided on the size- the "pistol" 11 inch or the "rifle" 16"? For the most part, i would go to indoor/ outdoor ranges to use it. Also, I prep for any future catastrophe- so...

We're 6-7 months post launch, so what do you guys think of the SIG M400 Switchblade SDI Pistol? Is it a pretender or contender? As I understand it, SIG has marketed this as "The Ultimate M400 Pistol", an out of the box competition ready AR. I feel its build specs set it up to be an equivalent...

Yes, I have said "Sawyer" in the past. Wanted to join the forum to get more information and bring any troubleshooting here I might have for those who have more knowledge than myself. I just picked up another Sig Sauer yesterday and figured it was time to join the cult. (Even if I switched from...

Hi All, In these days of scarcity, I'm looking to buy a rifle - some sites no longer have the "regular" version of several AR-15 brands, but have their Colorado-compliant versions. Based on what I can tell, the Colorado rifles seem to only have a 10 round magazine to comply with the law. Is...

Hi Community, New poster here. I own a P226 from Sig and am quite happy with it, so I'm looking to add an AR-15 to my collection and thought about sticking to Sig. Back in 2013, someone had this exact question here: M400 Proprietary upper/lower? The article was extremely helpful for me...

Hi im pretty new to this and i have found out that my rifle doesnt like steel casings and due to the current shortage on everything i was looking to swap it out with a BCG that could better withstand both steel and brass after all when **** i need to be able to use whatever is available

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...

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...

Hello everyone, I'm Sean. I just recently made my first sig purchase when I got the Sig M400 Tread and was so pleased with the workmanship and quality that I bought the Sig P2022 a couple weeks later. So far I have around 500 rounds through the M400 and 100 or so through the 2022. I am very...

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...

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...

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...

I have a sig m400 with a carbine length magpul MOE handguard and picatinny rail gas block. I have tried to supply a picture but not sure if it will work. I am trying to change the handguard to a mid length magpul MOE. can anyone help me out with the best way to do that? Do I need to add a...

[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...
