    So you have a logo on a Pic rail optic…. to KNOW it’ll fit a pic rail? Who exactly is the target consumer here?



  2. Max K on December 6, 2021 at 10:41 pm

    Can you take the yellow tread logos off?



  3. Wilson Hensley on December 6, 2021 at 10:43 pm

    Do NOT be fooled with the Tread Iron Sights! I ordered them, didn’t work (front post too high), called Sig & they told me "the M400 was NOT designed for iron sights"! I told them about this video, and its claim, and they changed the subject to offering a return label for my troubles.

    Sig, u can do better!!



  4. Russ Olson on December 6, 2021 at 10:44 pm

    Just bought an m400 tread. You should send a rifle to Mrgunsngear for a review.



  5. Ballistic & Apex on December 6, 2021 at 10:44 pm

    Why Couldn’t Sell a Barrel nut wrench for this? Or may sell this tread with a 15 inch full picatinny rail. We Support you SIG but don’t make your Consumers feels inferior for using your products.



  6. talonakins on December 6, 2021 at 10:48 pm

    Can we use the verticals on the tread AR pistol



  7. Thomas Anonymous on December 6, 2021 at 10:50 pm

    I don’t understand the logic behind the all proprietary accessories? reminds me of why I won’t buy an APPLE i Phone, and what’s with the tapered muzzle? explain that, stuck with Sig Tread muzzle device? lets not forget the equally ridiculous handguard the requires, again a proprietary SIG pic rail or you won’t be able to zero your front iron sight? childlike, just dumb



  8. Joel Dorsett on December 6, 2021 at 10:51 pm

    Wheres rhe best place to get this gun



  9. Jason Shackelford on December 6, 2021 at 10:52 pm

    What rifle sling do you recommend with the Tread?



  10. Spence Miller on December 6, 2021 at 10:52 pm

    I bought my M400 on 8-10-2020, just waiting for my NICS to come back, average time here in Jersey is 5 days for it to clear…



  11. Alijah Murphy on December 6, 2021 at 10:53 pm

    Please send me one to review and keep. Thanks.



  12. TheDroneScene on December 6, 2021 at 10:53 pm

    So when will you make a handguard for the m400 tread pistol?



  13. M A on December 6, 2021 at 10:54 pm

    those iron sights are garbage, i’d take the mbus over them.



  14. T Ti on December 6, 2021 at 10:55 pm

    What is the best laser light for the m400 tread pistol?



  15. Nomadic Wanderer on December 6, 2021 at 10:56 pm

    How do I get the hand guard with the yellow logo ??



  16. James Callahan on December 6, 2021 at 10:56 pm

    I want everything is this a package



  17. neverlost0121 on December 6, 2021 at 10:58 pm

    Tells me BUIS are “hella important”, then neglects to include them with the rifle. Come on Sig, including the sights and the ambi charging handle would’ve cost you next to nothing.
    Also, can we get a more utilitarian hand guard with a full length rail and M-Lock in the 45 degree positions?



  18. Kyle G on December 6, 2021 at 10:58 pm

    Other than the ambi and gas mitigation features is the charging handle mil-spec per say? I found it odd they referred to everything as specific to the M400.



  19. John Heueisen on December 6, 2021 at 10:58 pm

    Can anyone tell me the manufacturer of the work shirt he’s wearing??? Odd question I know.



  20. Captain Weston on December 6, 2021 at 10:59 pm

    Can those yellow inserts come off the hand guard?



  21. Denver Hardin on December 6, 2021 at 11:00 pm

    I love everything but the handguard is trash. The Upgraded ones are better but ehhh. I wish sig offered a Tread handguard with a Picatinny rail all the way across the top



  22. Rx Doom on December 6, 2021 at 11:00 pm

    Only problem is finding any of this in stock ☹️



  23. Mx2 CE on December 6, 2021 at 11:02 pm

    No not the UBER lol



  24. Taylor C on December 6, 2021 at 11:02 pm

    Does the yellow Tread badge come off easily?



  25. Rob ran on December 6, 2021 at 11:03 pm


  26. Joystick Legion on December 6, 2021 at 11:07 pm

    I’m new to Sig Sauer and I just bought myself an Sig M400 Tread! I’m thinking about buying a Romeo 5 for it but I want flip up sights too and wonder if you can equip both on it and possibly use them to co-witness with the Romeo 5?



  27. Big Daddy 86 on December 6, 2021 at 11:08 pm

    I wish they sold their handguards in other colors than just black



  28. Mr. Pabs on December 6, 2021 at 11:09 pm

    Hey SIG, why could’t you just sale the M400 with the upgrade 15" hand guard right out of the box? the hand guard that comes with this rifle is useless because it gets too hot with rapid fire and you can’t attach a handle closer to the receiver. Please be more considered with your costumers, don’t hate us.



  29. 889976889 on December 6, 2021 at 11:10 pm

    Romeo 5 is not motion censored! Wby does every sig review I watch say it is! I have the Romeo 5 it has to be manually turned off and on.



  30. Gregory Barker on December 6, 2021 at 11:10 pm

    I’m looking for this rifle on gunbroker and I notice that some sellers have the "TREAD" symbol on the side of the hand guard and some do not, yet they’re all listing it as SKU RM400-16B-TRD. Is this a detachable plate that comes with the rifle, or is there some other explanation for this variation?



  31. Michael Cummings on December 6, 2021 at 11:11 pm

    So the M400 Tread is 7lbs with the original handguard how much does it weigh with the upgraded 15in handguard?



  32. Ben Turner on December 6, 2021 at 11:11 pm

    it would have been nice to have had iron sights on the sig out of the box. Love the rifle but it should come with ironsights since its not a shotgun.



  33. Allen E on December 6, 2021 at 11:12 pm

    Buy a M400…ships in cardboard box & no picatinny mount for front sight. Also machine few more mlok hokes in stock hand guard be nice. Pretty ghetto Sig.



  34. Jose Navarrete on December 6, 2021 at 11:13 pm

    Any sling mount that would fit it



  35. AshamedTripod2 on December 6, 2021 at 11:16 pm

    Inflation makes this video a liar. I paid 169 + tax on my romeo sight yesterday



  36. diypunx on December 6, 2021 at 11:16 pm

    Has Sig fixed the issue with the flip up Iron Sights not having enough adjustment to be zeroed in correctly?



  37. mike barile on December 6, 2021 at 11:16 pm

    Why didnt ambitious charging handle come with rifle if everything else on rifle was supplied



  38. Big Daddy 86 on December 6, 2021 at 11:18 pm

    Can I get all of these attachments in FDE?



  39. justus005 on December 6, 2021 at 11:19 pm

    Where are the front sight rails SIG? Cannot find those darn things anywhere!



  40. Edgar Estrada on December 6, 2021 at 11:19 pm

    Is there an installation video for the tread vertical grip.



  41. mlittle008 on December 6, 2021 at 11:21 pm

    would be nice if the hand guards were available. The M-lok handguards should’ve been stock with the gun.



  42. Dre Vis on December 6, 2021 at 11:23 pm

    Can parts be cahnged with normal millspeck parts.



  43. Cokonut Life on December 6, 2021 at 11:24 pm

    Since Sig doesn’t have any of these accessories in stock to sell, does anyone know anyplace else that carries these that would have them in stock? Thanks



  44. Arsenick on December 6, 2021 at 11:24 pm

    dead link



  45. Chris Ortiz on December 6, 2021 at 11:29 pm

    The stock hand guard 🗑🏋🏻‍♂️



  46. midwestgrunt on December 6, 2021 at 11:29 pm

    Sweet choker.



  47. Jannet Fate on December 6, 2021 at 11:30 pm

    When I first see people commenting about a store called *immaglockdealer on wickr* I think it a bot until when I hit them up and find out is the best plug ever you can also deal with them



  48. Rat zo on December 6, 2021 at 11:32 pm

    Make sure to buy sigs rail if you plan on using iron sights.



  49. 370HSSV on December 6, 2021 at 11:33 pm

    i think they did all this intentionally. why? because its an Affordable rifle so they took out all the good stuff. makes sense



  50. Daniel S on December 6, 2021 at 11:38 pm

    I was very shocked how much suppressors cost. I’m new to the rifle game.
