Unboxing - Sig Sauer M400 Tread 

Hey Shipmate. Navy vet here too. As a lefty, I didn't like our m4s either. I now built a lefty and it's entirely different. 🤙

Bought 1 today on sale for 750

@@UnicornMeat512 Great deal. I'm a bit jealous.

They are quality ARs and if recommend them to anyone looking for purchase one for the first time.

@@GunBoxTherapy Yes Sir,I agree the best purchase I've made so far.As far as AR's

When you look at the price and the upgrades that are included in the box and then the materials used in the barrel and BCG, I definitely would call it a very good entry level rifle. Sig also markets it as such. Don’t get me wrong, it is a GREAT rifle but I wouldn’t call it “top tier”.

Definitely not entry level

My opinion is that this was definitely going after anyone who doesn’t own an AR but wants to get into them. If you do own one and have upgraded things on it such as grip, handguard, safety selector...etc. I’d say just build one you want for much cheaper.

@@GunBoxTherapy I got a M&P 15 Sport 2 back in 2019 when they were crazy cheap. It's dead stock, Ive only mounted a Romeo 5 dot. It's just a cheap plinker, the only thing I'd upgrade is the pistol grip. Building honestly does look like the best option, especially when it comes to beating these outrageous prices. If I were to buy another rifle right now, It'd probably be a Zastava zpap just because its "cheaper" to shoot compared ARs at the moment. Budget AR15s like the Sport 2 and Tread being borderline $1k is ridiculous.

Sig cut corners deciding on how to make tread pistol. Don’t buy.

You can attach another muzzle device to the barrel. The muzzle device on this example is not designed for use with a suppressor.

Get yourself an AR tool, place the rifle on a chair with the barrel hanging off the seat. Sit on the AR and use that as leverage to remove the factory flash hider, replace with a Surefire warcomp and you have yourself a suppressor ready sig.

To do this right, you will need to make sure you have an "adjustable" BCG (Bolt Carrier Group) for a Suppressor... so, yes, you can have it on the Sig, you just need to replace another part. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-fmhcs34rYSg.htmlsi=3M7aqRHyQPtD6q7B&t=661 Also, look into adjustable gas blocks. Pretty much tuning.

It’s super easy man! Just go slowly and don’t let anything pop out and launch somewhere. lol. So, first step is ensure it’s safe. Okay. Now push out your rear takedown pin and your front pivot pin. With the bolt forward now remove the upper. The following steps will all be done with the magazine well to your left. Now. You’ll see your hammer and it should be locked in the rearmost position. Now place the safety on fire and with your other hand hold the hammer and DO NOT let it slam forward. Pull the trigger and slowly guide the hammer forward. Next, there are two pins on the side of the receiver. One that’s closer to your bolt release paddle and one slightly lower than it but to the right. These two pins during both installation and removal are driven on from this side (the left side of the receiver) and out of the other side. You can go the other way but it’s much easier this way. Now drive that pin out that’s closer to the bolt release paddle. Your hammer may want to work itself out just hold on to it with your hand. And pull it out with its spring. Now drive the other pin out that’s lower and to the right of that pin your just removed. Here you will find that this isn’t under so much spring tension but you may be left with two parts. Your trigger shoe and your disconnector. Place these old parts aside but keep them just in case. Now if your new trigger is an enclosed unit, the rest will be easy. Just place it in and push those pins back. If it isn’t then you will want to look up a video on installation as springs need to be placed in a certain orientation that’s hard to convey via text. Im gonna link you this Larry Potterfield video on FCG installation. Good luck man! After you do it about 3-4 times, you’ll be a pro and start teaching others. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-blDByRL9-co.html

@@GunBoxTherapy I can't tell you how much I appreciate you taking that much time effort to reply to me. I'll try it out in the morning. Thanks again and have a great weekend.

No problem man! Have fun!

@@GunBoxTherapy I truly do appreciate this comment. Rare to see a guntuber reply, much less go into such detail. Preciate ya man!

Thanks man! Yeah, I attempt to reply to as much as I can when I can.

It is which leads me to believe either the materials are different types of alloys or the anodizing is done separately which would give you shade variations.

When I got mine a year ago, it was $799.99 but that same store now lists it for $849.99 last I checked. That was without any accessories or sights. I have seen some unboxing vids where the rifle comes with a Romeo Red Dot and a forward grip on the handguard but I'm assuming that's special edition or something.

@@1977Yakko I got mine for $1200 😤

@@nateb9346 Did that come with a red dot optic?

@@1977Yakko No way, didn’t even come with those yellow tread branded rail covers 😂.

@@nateb9346 Well, I'm glad you got your hands on one. The Sig Romeo series of Red Dot optics are pretty affordable. Generally in the $125-$200 range. Sig also makes some flip up iron sights but I got mine from Magpul. Speaking of Magpul, I'd load up on their 30 rd. pmags. They're affordable and reliable.

If your hammer is not back it will not go to safety. So if you dry fired it or lowered the hammer then closed it back up, it will not go into safety. Pull charging handle and then try it.

That would be a damn good upgrade!

I wouldn’t say any AR would be good for starting out. What I mean when I say that comes down to reliability, build quality, ergonomics and feel. Reliability for a new shooter is extremely important as they are going to expect it to work upon using it. Build quality is dimensioned typically as total price decreases. So the Tread strikes a balance in high build quality for a slightly higher price tag. Ergonomics and feel. This is probably the most important thing to a new shooter and they don’t even know it yet. The upgraded grip and stock (2 of the three things that contact the body when shooting) on the Tread are worlds better than the standard A2 grip and stock. So yes, when I say this is a great AR for those starting out, I believe it’s true for those reasons. And your typical experienced AR owner as they learn about metallurgy within BCGs and barrels, better handguards, furniture setups they like in terms of ergonomics…they will most likely gravitate towards higher end ($1500+) or just build their own piece by piece.

Just pull on it hard. It will pop off.

Agreed. I was more so describing who Sig markets it and the “Tread” line towards.

@@GunBoxTherapy first quality AR-15 for sure

Definitely man! I wish I could find just their lower somewhere. The ambi controls are very well engineered.

@@GunBoxTherapy agreed I have an entry level bushmaster qrc it was my first rifle and I have a colt cr6920 I got when Biden announced he was going to ban ar14s lol. So I need a mid level game changer and my local store has a sig m400 tread for 849.99 right now. I upgraded both rifles to make them what I wanted but only time will tell if the 700 dollars more spent on the colt was worth it. I also considered a Springfield saint I had 1 never shot it and sold it to a co-worker. We are in corrections.

Maaaaaan I paid $1200 for mine here in California.

@@nateb9346 $799 here in Montana

@@UnicornMeat512 Nice, just another reason why California sucks.

@@nateb9346 I'm from California. The grass isn't greener over here except where guns are concerned.
