    What about a .410 shotgun upper?

  2. Timilehin Odimayo on December 7, 2021 at 1:37 am

    You’re doing a really good job sir!

  3. sharpest shed tool on December 7, 2021 at 1:39 am

    There is a better option to get a multi cal system and it’s also lighter and less expensive. 3 calibers ,one upper one lower 2 bolt carriers total weight 9.5 lbs

    What type of trigger is that red one?

  6. AnthonyG_Lifestyle on December 7, 2021 at 1:42 am

    Can you take a complete 5.56 upper and combine with a complete .223 lower? Thank you in advance

  7. Ben Dover on December 7, 2021 at 1:42 am

    Your upper and lower are different shades of black, I hate that! When you build your own colors never blend. Get a Daniel defense and it will be the last gun you ever buy. The barrels and ports are cold hammer forged. It’s pricey at $1700 ballpark, but everything screams Ferrari of the gun industry in my honest opinion. I don’t have one, but seen, used, and coveted for a long time..

  8. Mike Bergquist on December 7, 2021 at 1:43 am

    I shoot 556/223, .CMMG 22 lr, 300AAC, 350 Legend out of my AR’s.

  9. erratic static on December 7, 2021 at 1:44 am

    5.7X28 will work and actually 7.62X39 with the mags that are made to fit a standard ar lower! yes, they do make them because i built 7.62X39 ar using a standard ar lower.

  10. Randy Boteilho on December 7, 2021 at 1:45 am

    Can the 22 long Rigel shoot17 her ? I have a multi cal rifle….

  11. Ricardo Chique on December 7, 2021 at 1:45 am

    One other caliber that’s fun to shoot is a 17hmr that’s available for the AR15 lower

  12. leokadya trotter on December 7, 2021 at 1:46 am

    350 legend

  13. Steve k1177 on December 7, 2021 at 1:46 am

    Love the videos love the knowledge. I know that 357 can shoot a 38 special and 556 can also shoot a 223 REM. But are there any other calibers that can be used like this

  14. Kevin Riecke on December 7, 2021 at 1:48 am


  15. Burn Em Out Fitness on December 7, 2021 at 1:49 am

    How would I look,buy or build a AR 15 ( rifle not pistol ) to shoot 10mm ?

  16. Caleb Gann on December 7, 2021 at 1:51 am

    The absolute best magazine to run multiple calibers with is the Unimag Gen II. It works so flawlessly for so many calibers. My go to especially for 458 socom and 7.62×39

  17. Gatlin Jenkins on December 7, 2021 at 1:51 am

    These are AWESOME! I got one in 7.5" and use that same folding adapter. Cool part is just don’t use that plug (being a 22 u don’t need the buffer) so u can shoot it folded or not

  18. Ethan .A. on December 7, 2021 at 1:52 am

    Do the m&p 15-22 mags work with the cmmg bolt

  19. ᖀᖇᓮᙜᙦ 8 ᖴᕶᕓ on December 7, 2021 at 1:54 am

    i dunno mane.
    I’d rather spend a few extra bucks and get a dedicated lower. I guess I can understand the rationale for people who are budget ballin, but it’s just not for me.

  20. Tim on December 7, 2021 at 1:54 am

    what a 6.5mm grendel?

  21. Clark Rachesky on December 7, 2021 at 1:57 am

    How about the 450 bushmaster, great round, not cheap however the prices for the ammo are staying consistent while the other calibers have been rising

  22. KG on December 7, 2021 at 1:59 am

    They hold 25 rounds. Also, you can save some money by buying the 10 round mags, disassembling them, pushing out the pin that limits them, reassemble them, and finally enjoy your 25 round magazine.

  23. Alejandro Moreno on December 7, 2021 at 2:00 am

    7.62 ×39

    Changing out the buffer and spring for the 300AAC Silenced with 245 grain and 208 Grain Hog Stoppers. With a good mention: However, do not have to change out the buffer and spring when using my 125 grain and 150 grain 300AAC Hunting Rounds (Un-Silenced). You can run the hell out of it . Silenced and Un-silenced with above mentioned and mid to high quality ammo and re-loads.

    Currently working on another built out lower Assy so I can dedicate the original STAG Lower for the silenced 300AAC SBR Upper.

    Great and Informative Video.
    Thanks! Charles

  25. ickyiceful on December 7, 2021 at 2:00 am

    Theirs more then 4 calibers u can shoot out of a standard 50 cal bolt action upper 458 semi auto 223-556 300 black out 2lr 9mm 45acp I’ve even seen a prototype bolt one that’s common hunting calibers or for whatever you can find 270 30-06 338 308 300 win mag

  26. Michael Alvarado on December 7, 2021 at 2:01 am

    50 beowulf

  27. mike on December 7, 2021 at 2:04 am

    5:10 wasn’t paying attention and thought I watched this guy build an SBR on camera 😂

  28. Victor Tijerina on December 7, 2021 at 2:05 am

    Do you need to change stock spring if going from 300. Blkout to 5.56?

  29. Justin Gonzalez on December 7, 2021 at 2:07 am

    Didn’t see a link for the aero precision lower you used any way you can tell me which lower that was I’d like to pick one up

  30. RadShad310 on December 7, 2021 at 2:08 am

    You can shoot 7.62×39 and 6.5 Grendel as well with your stock AR15 lower. Just make sure your trigger is more stout for the 7.62.

  31. OCGunVibes on December 7, 2021 at 2:11 am

    “Slave state” 💀 lmao

  32. jonathan humphrey on December 7, 2021 at 2:11 am

    We all need a .50AE AR15

  33. I Truck on December 7, 2021 at 2:12 am

    6.5 grendel

  34. Marshall morris on December 7, 2021 at 2:14 am

    The cmmg kit runs best with high velocity 22lr

  35. TheAnalyst on December 7, 2021 at 2:15 am

    You didn’t need to change lowers for the cmmg kit, it has it’s own buffer spring built into the bcg.

  36. Chris Certa on December 7, 2021 at 2:17 am

    A good tip with the CMMG 22lr conversation is that you run a few rounds of 223/556 after shooting the .22 to clean up the barrel and gas ports

  37. Spencer N on December 7, 2021 at 2:20 am

    How do you like the Holosun 510c? Thinking about getting one for my ar pistol.

  38. Garage Innovations on December 7, 2021 at 2:20 am

    Thinking about a .350 legend as it uses the same bolt ar 5.56.

  39. James Gardner on December 7, 2021 at 2:21 am

    You technically forgot a dozen or so calibers, if not more, that work on standard ar-15 lowers. 224valkeryie,
    6.5grendel uppers and magazines & the new 6arc, 300ham’r/7.62x40WT,350 legend, 450 bushmaster, 458 socom and 357 socom, 50beowulf and the list goes on.
    Honestly this is the first video from your channel I have watched, only watched because my phone kept insisting I watch it in my notifications bar for a week, thought it was going to be silly because as I stated, many cartridges can be fired atop a standard ar-15 lower.
    That said, I did learn quite a bit. I had no idea you don’t need a barrel change to fire 22lr, which I suppose I have some questions about the how on that as I don’t grasp how the chambers could possibly be compatible. Also learning about the 9mm magguts for ar-9 and specifically the DRB CMMG banshee uppers, that is definitely freaking awesome! And I totally want one of their uppers now!
    So in conclusion, thanks for the informative video, but the title of the video kinda through me off for a while.

  40. olafspetzki on December 7, 2021 at 2:22 am

    The reason for that .22lr bolt hold open is probably to avoid dry firing a rim fire mechanism with every empty magazine. Makes plenty sense to me 😉

  41. TheLethalPredator on December 7, 2021 at 2:25 am

    Before watching I’m gonna try to guess, .22, 458socom, .50beowulf, 9mm, I only know those is because my brother used to have .50beowulf and .22

  42. dodanim gandara on December 7, 2021 at 2:28 am

    Would these adapters fit on a 300blk upper?

  43. Buck Jordan on December 7, 2021 at 2:28 am

    You definitely committed a felony in this video. I’ll let you figure it out though.

  44. Elevator Music Vlogs on December 7, 2021 at 2:30 am

    Steve Steve Steve

  45. Tactical Shooter on December 7, 2021 at 2:30 am

    Thanks! Now I have a reason to waste money! But seriously wish I knew this before buying a 22 rifle but will definitely buy this to have fun

  46. Michael Alvarado on December 7, 2021 at 2:30 am

    You should ry 410 gauge !

  47. juedo34 on December 7, 2021 at 2:31 am

    2.77 wolverine and 350 legend both use the 5.56 bcg

  48. brandon griffin on December 7, 2021 at 2:31 am

    7.62×39, .458 socom, 50 Beowulf, 50 Bushmaster, 350 legend. I have a 458 socom one of my favorite guns to shoot does take slight modification to the magazine to make feed right preferably using lancer mags

  49. Shane Sischo on December 7, 2021 at 2:32 am

    This just came up in my algorithm. Can’t believe you just said, $.28 a round for 556

  50. Jeremy V on December 7, 2021 at 2:34 am

    223/556 normally and with the bravo kit you can shoot 22lr.
