    Leave it to my wifi to be down when Gunmen uploads! Beautiful build visually, going by that BRoll it looks like it also runs SUPER SMOOTH!!

  8. Cameron on May 11, 2023 at 4:11 am

    Thinking about movin to Utah.Any suggestions on where?

  9. Killt00live96 on May 11, 2023 at 4:11 am

    This channel is amazing ! Maybe Benelli M4 next ???

  10. Eric Marsh on May 11, 2023 at 4:11 am

    Do a Remington 870 build!

  11. AnxietyNonstop on May 11, 2023 at 4:12 am

    And I was just thinking about getting a shotgun 😭

  12. WobblyBrute on May 11, 2023 at 4:13 am

    Now try the shorty shells. Slugs and buck. Great for women and children. You may need a adapter but it’s only $15ish

  13. Zane Dubé on May 11, 2023 at 4:16 am

    Too much crap on this gun. Give me a bead sight, 7 in the tube and I’m good. It’s a shotgun.

  14. SLED YT on May 11, 2023 at 4:19 am

    Goated firearms channel! Would love to see a Blackout Defense Quantum Mk2 build or at least your opinions on it.

  16. WobblyBrute on May 11, 2023 at 4:20 am

    590. Smart 👍👍

  17. Cody Lamaar on May 11, 2023 at 4:21 am

    Always really clean, thought out builds

  18. John FLdigz78 on May 11, 2023 at 4:23 am

    Looks sweet, but I’ve been told Shotguns have heavy recoil, I just got into long rifle platform like 3 years ago, but I’m a bit shy of shotguns.

  19. bfess on May 11, 2023 at 4:25 am

    I have been waiting for this video!! Thank you for the shotgun build😩🥲so beautiful

  20. Jonathan Miller on May 11, 2023 at 4:26 am

    what ear pro do you run?

  21. Jin Sage on May 11, 2023 at 4:26 am

    Nice build man

  22. K on May 11, 2023 at 4:26 am

    wish i have one

  23. Jack Greenstalk on May 11, 2023 at 4:28 am

    S&b 12 pellet is excellent stuff for great price 🔥💥👍👍 nice setup. Funny the maverick 88 would almost be better ergonomics for safety but just leaving it off and running "cruiser ready" its very safe in storage but ready for action with a single pump

  24. László Szabó on May 11, 2023 at 4:32 am

    Pistol grip prevents quad loads which is the most powerful shotgun tactic imo. You should consider learning it.

  25. Anthony V on May 11, 2023 at 4:34 am

    After this video i need one such badass setup 🤘

  26. Will L on May 11, 2023 at 4:36 am

    This channel is so epic. This guy puts stuff on his guns I didn’t even know existed lol. I have the 590a1, i might actually get that voa handguard. That looks fire

  27. Tristyn Garza on May 11, 2023 at 4:37 am

    Hell yes man, bro only puts out good content

  28. Deston E. on May 11, 2023 at 4:39 am

    I admit that I haven’t watched much of your content. However, the content I have watched has been great. I don’t watch a wide variety of guntubers, so this might not mean much but the production quality of your content is more than superior to similar stuff I’ve seen. When I discovered your channel, it was your video covering your AR-15 build. I can’t say I was expecting much, but I was absolutely blown away. I hope to be able to do stuff like this myself one day. I’ll continue to watch and enjoy your content for as long as you release it.

  29. Lowtan19 on May 11, 2023 at 4:39 am

    New subscriber that came just in time. Caught your 590 review and just before your AK build. Lovin it

  30. Firstimeshooter on May 11, 2023 at 4:41 am

    Scalarworks sync/03. Low as you can go with a shotgun red dot. 👌 love mine. Ditch the modlight and use a unity tactical mlok hot button.

  31. Henry Graham on May 11, 2023 at 4:43 am

    Wonderful build. I also run the mesa stock system and love it. Great vid

  32. David Konechne on May 11, 2023 at 4:44 am

    Starting to become one of my favorite channels! Keep up the good work!

  33. Briarwood on May 11, 2023 at 4:47 am

    I just bought this shotgun today!

  34. Jake Pittman on May 11, 2023 at 4:48 am

    You look like Warden from R6

  35. rob BER on May 11, 2023 at 4:50 am

    Another great vid @Gunmen. Just bought that Amazon EDC belt after watching your vid on them. Its my 4th EDC belt and definetly my favorite.

  36. Henry Krinkle on May 11, 2023 at 4:53 am

    you get a like just on the B-Roll alone…………. thank you for the great content

  37. Resitance IsFutile on May 11, 2023 at 4:53 am

    I already decided on getting a Mossberg 590 as my first boomstick. You just gave me a whole new world of ideas of what I can do to customize it. I ended up buying a 43x after being inspired by your builds. Great content!

  38. NOLES32809 699581 on May 11, 2023 at 4:54 am

    That’s probably the nastiest 590 I’ve seen yet

  39. Jared Long on May 11, 2023 at 4:54 am

    Super clean! Love the vids keep up the great work

  40. Will on May 11, 2023 at 4:56 am

    I’m a huge fan super excited for the USAC Moth video. Website is 100% worth the subscription

  41. SchizoSaint on May 11, 2023 at 4:57 am

    Geez your production value is insane. We could all take notes. Great stuff man!

  42. Huy Thiện Bùi on May 11, 2023 at 4:57 am

    so sastisfied!!

  43. SupFoo on May 11, 2023 at 4:59 am

    Remington 870 gang GANG

  44. Joseph Torres on May 11, 2023 at 4:59 am

  47. Alec Volles on May 11, 2023 at 5:00 am

    Why don’t you wear ear pro while shooting?

  48. DonDadaTopShotta on May 11, 2023 at 5:01 am

    Crazy that you dropped this video today, I woke up today and was searching on YouTube for stuff to finish my personal build with this same gun

  49. Jesse Orr on May 11, 2023 at 5:02 am

    If you’re looking for some alternative attachments for other builds, check out fernilab. He’s got an MLOK mount for cloud switches. Not sure it’ll work on this but something to look into!

  50. Vang Comp Systems on May 11, 2023 at 5:03 am

    Bro…awesome work. This video is amazing. Hopefully you enjoy the shotgun and the rest of the Vagn Comp work for many years to come. Keep up the amazing work, we’re all rooting for you!
