What You Didn't Know About the HK416 & How To Build Your Own

What You Didn't Know About the HK416 & How To Build Your Own

The Heckler & Koch HK416 is an updated, piston-action derivative of the M4 carbine. It’s been issued to U.S. Special Forces troops – and yes, it’s the rifle used by the Navy Seals who ended the career of Osama bin Laden. Now, you can assemble your own with an HK416 parts kit from Brownells. Broken down from complete German rifles that saw little-to-no use, these kits lack only the lower receiver, barrel, and bolt. The good news is Brownells offers those parts separately, so you can get ALL the components you need to build a complete, semi-auto HK416 rifle. In this video, Paul Levy explains the differences between the HK416 and the M4, and then he shows you how assemble an HK416 kit.

    I wish I had $4k to blow on this… or spend less than half on a Sig MCX

    What a beauty



  3. AppalachianGunSlinger on September 30, 2022 at 8:21 pm

    Honestly ain’t a bad price considering that you are looking at $15 for a post sample version as well as a company who imported and made these sans the factory barrel and bolt for $13k.

    Ok Mr. Burns you win. But beware we Germans aren’t all smiles & sunshine…

    Oooooooo the Germannnnnnsss!



  5. KaotixMusic on September 30, 2022 at 8:24 pm

    it was adapted by Naval Special Warfare – not Special Forces.

    Here I am looking up a parts kit thinking it’s cheaper to build than buy the MR556…. I was wrong. Looks like the MR556 is the way to go

    buffer tube is commercial spec ?



  8. green street on September 30, 2022 at 8:31 pm

  17. Pepe Le Pew on September 30, 2022 at 8:40 pm

    Idek why I’m complaining about the price of one of these when I’m most likely never going to get one. I’m literally bored at 2am.



  18. Chanis Manolito on September 30, 2022 at 8:41 pm

    That’s basically me556



  19. 22BStan on September 30, 2022 at 8:45 pm

    Just sell some complete.



  20. tsafa on September 30, 2022 at 8:46 pm

    How many years until the HK 416 patent expires and we can pick up clones for $500?



  21. Anthony Amezola on September 30, 2022 at 8:46 pm

  25. gordy505 on September 30, 2022 at 8:54 pm

    converting MR 556 cost as much as if not higher believe me I’m doing it threw Investment Grade Firearms my Mr556 was sent off in March this year and to this day NOTHING This is NOT bad wish i seen this earlier



  26. Guns N' Doodles on September 30, 2022 at 8:56 pm

    You all should make a heavy barrel option so that way you could make an m27 clone mate!



  27. Mannie Halmagean on September 30, 2022 at 8:57 pm

    You guys think at BROWNELLs have hk416 parts in the future.



  28. Stephen Ralph on September 30, 2022 at 9:00 pm

    Where’s my wallet?! Nice job Brownells.



  29. tm530 on September 30, 2022 at 9:01 pm

    I have 2 questions for Brownells on this build. First, I did not see any grease used on the receiver extension/barrel nut during assembly. Is there a specific one recommended? Or just the same grease that one would use on any AR assembly? (moly?) I have removed the barrel nut on a factory HK MR556 and there is some kind of grease there. Second, I did not see a Go, No-Go or Field gauge used to check head space after assembly? Is this something that was done off screen or did you skip it? And if so, why? Thanks in advance!



  30. Killa on September 30, 2022 at 9:03 pm

    The rifle that greased Osama. Love it.



  31. Evan Owens on September 30, 2022 at 9:03 pm

    Yeah these will be in stock for about 23 seconds every 15 years



  32. Him: DACLONE ON TELEGRAM on September 30, 2022 at 9:03 pm

    Just bought mine today from a store called *immaglockdealer on Wickr* with 12 ammo I need someone who will teach me how to firing it



  33. gordy505 on September 30, 2022 at 9:04 pm

    for those who don’t want to pay ….don’t and for those of who that will great Browell gives you an option … pity so much complaining This is a nice option that buying Police trade-ins off Gun Broker with unknown shot count barrels



  34. Ann Lee on September 30, 2022 at 9:04 pm

    Costly



  35. Doomsday ツ on September 30, 2022 at 9:05 pm

    When putting on an after factory barrel on a HK MR556 what’re the torque specs required? and what else is needed to be known? headspace? etc



  36. Trooper Nate on September 30, 2022 at 9:07 pm

    Cool



  37. dots on September 30, 2022 at 9:07 pm

    Basically an m27



  38. Full Movie on September 30, 2022 at 9:08 pm

    Can I ask why the HECKLER & KOCH – 416 PARTS KIT is discontinued?



  39. Tommy on September 30, 2022 at 9:08 pm

    Gun deprived Europeans are tortured by watching this. Please feel sorry for us, and send us some thoughts



  40. DerWaidmann on September 30, 2022 at 9:08 pm

    Are your uppers compatible with AR15 lowers?



  41. B on September 30, 2022 at 9:08 pm

    Can a civilian even buy these if they are sold with an auto trigger or sear?



  42. matchbox3eb on September 30, 2022 at 9:08 pm

    Damn…. it’s…so… beautiful 😭😭😭



  43. Ron i on September 30, 2022 at 9:09 pm

    Is the Brownells barrel cold hammer forged?



  44. 1 on September 30, 2022 at 9:09 pm

    Not sure if this has been mentioned yet or not, but the first part of the video assumes that lower has standard AR parts, and installs like a normal AR15. This is not true. Please do another review of the assembly of the INTERNALS of that lower!



  45. Dxp Vxo on September 30, 2022 at 9:09 pm

    Cool. But a waste of money.



  46. Execprotect on September 30, 2022 at 9:10 pm

    Awesome video.



  47. Hanlon Kitto on September 30, 2022 at 9:14 pm

    Yeah it’s almost a 416. Except for the whole missing the bolt, lower, and barrel thing.



  48. DownTheRange on September 30, 2022 at 9:14 pm

    Beautiful great video superb instructions on how to put your own together thanks to Brownells absolutely fantastic 👍🏻



  49. Ann Lee on September 30, 2022 at 9:17 pm
