    How bout 10mm



  3. Frankie Hernandez on October 27, 2021 at 5:49 pm

    Where can I buy one just like this completed and the same to please help



  4. Mason S on October 27, 2021 at 5:52 pm

    So if I were to buy the two parts that you mention in the description what else would I need to buy to have a functioning firearm?



  5. olysean92 on October 27, 2021 at 5:53 pm

    AR-45 is a 45 caliber 300AAC subsonic with double the ammo in the same space at half the cost. If you want the additional versatility of supersonic plus loads, ARx39 is the cost of 45ACP and keeps going when 300AAC runs out of room in the case for powder. 300AAC is now obsolete. Let’s argue.



  6. Mortimenow on October 27, 2021 at 5:53 pm

    Still want to see this in 40 S&W. Yeah I said it.



  7. Adrian Padgett on October 27, 2021 at 5:53 pm

    Looks like a modern day Tommy gun.



  8. Ed Becka on October 27, 2021 at 5:53 pm

    I went to the upper mfgrโ€™a site and they donโ€™t show a carbine length upper.



  9. Talon Gunter on October 27, 2021 at 5:55 pm

    Who made the upper I’m looking to build a ar45 acp



  10. shane sizemore on October 27, 2021 at 5:56 pm

    I want



  11. Patriot MJB on October 27, 2021 at 5:59 pm

    Do you have a coupon code for optics planet or joe o outfitters?



  12. Dustin Smith on October 27, 2021 at 6:01 pm

    Is it possible to build this as piston driven?



  13. Talon Gunter on October 27, 2021 at 6:01 pm

    Can I use a radial blowback with that upper ??

  15. Mike on October 27, 2021 at 6:04 pm

    Just shoot twice with the 9mm.



  16. Austin Parker on October 27, 2021 at 6:05 pm

    Cool little gun



  17. johnormike811 on October 27, 2021 at 6:05 pm

    Happen to know if they make one with a couple more inches of barrel?



  18. Electric Larry on October 27, 2021 at 6:06 pm

    Can someone please tell me the title to his intro music?



  19. Glenn Roberts on October 27, 2021 at 6:06 pm

    ‘. MERICA that’s why



  20. Wade Harrell on October 27, 2021 at 6:07 pm

    Third reason is I already carry a 1911 and reload 45 auto so I can have a carbine that shoots the same ammo.



  21. CM Menzel on October 27, 2021 at 6:08 pm

    Have you tested the 3โ€ 45 upper from Alpha Shooting Sports?



  22. Chadmon Jackson on October 27, 2021 at 6:09 pm

    Will it run double stack mag’s



  23. Derek Ladwig on October 27, 2021 at 6:09 pm

    What length is the hand guard?



  24. Gunplay TV on October 27, 2021 at 6:09 pm

    Grab a Wolff Xp spring and the random burst fire issue will dissappear



  25. Christian Tillsley on October 27, 2021 at 6:11 pm

    What bolt carrier group are you using? Mine is failing to feed, bullets going in at steep angle



  26. Kenneth Draper on October 27, 2021 at 6:11 pm

    Now it only it had the buffer ontop of the upper with the bolt transferring energy through a lever so the buffer is pushed toward the muzzle. It could conceivably damp out recoil.



  27. Turdis Willskinz on October 27, 2021 at 6:12 pm

    Im going to build this exact pistol with a PDW brace



  28. tony lupo on October 27, 2021 at 6:13 pm

    Can a echo 2 binary trigger be used in it reliably!?



  29. kdbboxing on October 27, 2021 at 6:13 pm

    Can you put a part list link to your build? I like it a lot.



  30. 1funcar on October 27, 2021 at 6:15 pm

    Damn, I like it!



  31. Big Boss on October 27, 2021 at 6:15 pm

    You can build it cheaper. ๐Ÿ˜กAnd should be !!!!



  32. Jordan Brown on October 27, 2021 at 6:17 pm

    What gun is this



  33. LittleYorgee on October 27, 2021 at 6:18 pm

    Your first reason let everyone know you don’t know what you are taking about.



  34. Stephen Addair on October 27, 2021 at 6:19 pm

    I edc my Taurus pt145 millennium pro, I have 2 ar15s in 300acc and 223 rifles but I want a ar15 pistol in either 45acp or 10mm



  35. 5cbryant on October 27, 2021 at 6:19 pm

    Iโ€™m having trouble locating this exact upper



  36. Dustin guy on October 27, 2021 at 6:20 pm

    Yeah, too bad everyone is out of stock



  37. Los Ortiz' travel Adventures on October 27, 2021 at 6:23 pm

    So how’s it holding on after a year?



  38. Nexy on October 27, 2021 at 6:23 pm

    Ten rounds capacity is pathetic



  39. Greg Taylor on October 27, 2021 at 6:23 pm

    Nice



  40. Josh Shirley on October 27, 2021 at 6:24 pm

    Wish it was 10mm



  41. C. Rod on October 27, 2021 at 6:29 pm

    Thanks !



  42. Jesse Alvarado on October 27, 2021 at 6:31 pm

    Why? Freedom thatโ€™s why! ๐Ÿ‡บ๐Ÿ‡ธ



  43. Jonathan Mapley-Brittle on October 27, 2021 at 6:33 pm

    I built this with the 3" upper. I am having intermittent trigger reset failure. I checked assembly of the lower. Does anyone have any ideas what it could be? My thought is to upgrade the trigger assembly? Thank You.



  44. Dan J on October 27, 2021 at 6:35 pm

    Too bad they don’t make the 45acp barrel in a 8 or 8.5" .



  45. Sonny Helms on October 27, 2021 at 6:36 pm

    Can you shoot +p hollow points through it ?



  46. Brian Gorsuch on October 27, 2021 at 6:38 pm

    didnt leave email address in description



  47. Allen Avalos on October 27, 2021 at 6:40 pm

    How much are these? I just turned 18 and looking to buy one.



  48. Fabian Gray on October 27, 2021 at 6:40 pm

    Wheres the 10mm are they out of stock
    Only see 45?



  49. Jim C on October 27, 2021 at 6:42 pm

    .45 acp is not (hard to control from a pistol). I have pistols in .45 and 9mm. Some nearly identical. Such as my M&P in 9 and my M&P .45. IMO the 9mm is much more snappy than the 45. As much as I like 9mm the .45 acp is smoother shooting caliber (on average guys). Itโ€™s also no more powerful than a 9mm using comparable pistols and ammo type. The higher velocity of the 9mm more than makes up for the smaller slug. Itโ€™s a myth that .45 acp is this magic man-stopper caliber. I shoot .45 because it is slightly less recoil than the 9mm. I love .45 acp but you just canโ€™t beat the higher capacity of the 9mm with relatively the same, if not more, energy on impact. Iโ€™d take the .45 for only 3 reasons
    1) smooth firing
    2) sub-sonic so perfect for suppressors.
    3) .45 acp hollow points have low penetration in my texting with it.



  50. Francisco on October 27, 2021 at 6:43 pm

    great set up! DO you think the Wolfpack Armory AR-45 lower would work with the Alpha 45 upper?
