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

@Joshua Bressel I've never heard of a registered auto sear? Always been told that the firearm(receiver on an AR) must be registered with the the ATF as an NFA firearm. Parts that make a firearm convert, like auto sears, I thought were made illegal? Would like to know more about this legal auto sear? Who made it? I'm assuming same process as machine gun to possess?

[@jeffszakacs7508]

My 14.5 centurion arms socom barrel has the same notch for its gas block would I be able to use that barrel on a 416? as I would because of how strong the materials are in the barrel it has the MK 40 series 4150 CHF blanks that were made into colt SOCOM barrel but extremely tight gas block for as well as it being indexed and a very thick barrel and speaking of thick the chrome lining is extremely excessive it’s definitely a floral barrel so it’s gonna hopefully last time long time and hopefully get it on some SOT select fire lowers as it deserves but what’s the guy saying for a 416 for the 10.4 and for the 14.5 because if I could swap that barrel in I would one it’s chrome lime is it and has probably over par HK materials are mostly the better but the original barrel blank was meant for a saw type barrel I really feel that the systems are gonna be the future of AR platforms The BCG for example is a spring around the firing pin and I believe it has a spring loaded rotating bolt it would be nice to get one of those Miller gas block variance but they just started selling Built uppers and I would buy honestly I would want the 10.4 and a 14.5 both with the MK 1 rail if I wanted to go all out I’d send this shit out to get tanodized but you can use a regular ass lower rather than sending stuff out have that done and then giving it laser etched that’s going to be expensive long process oh week waiting for something stupid like an optic man even drives me nuts are but 1100 bucks for a belt for 16 upper basically add 100 bucks for a muzzle device at 1200 to 1500 with a geissele rail If you were going to do one of these build the rails do get hard to find sometimes and they also their triggers are hard to find if you get an HK lower make sure your trigger pin and trigger is the right trigger make sure it’s in HK made by GEISS Don’t just throw an SSAE unless you’re using a different lower which is easier you don’t have to worry about in the magazine issues by the GEN 3P Mag solved that

[@joseluiszuno1567]

Just realized I need to swap my gas block out but I used lock tight on my suppressor mount. 😢😢😢

[@joeortiz8218]

Are the uppers receivers standard MilSpec striped receivers

[@Spinalcell]

Great vid and build, ty Brownells

[@DerWaidmann_]

Are your uppers compatible with AR15 lowers?

[@ARC928]

Is the Brownells barrel cold hammer forged?

[@tm530]

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!

[@brownells]

Standard procedures, including lubrication, should always be used when doing a build. Same with go/no go headspacing. Due to YT regulations and time constraits we often leave things out. This is also why you dont see "How To" builds any longer.

[@fullmovie7325]

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

[@spookyindeed]

They only got a few surplus kits from Germany.

[@redfernsoljah]

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.

[@Pluhdao]

Need more BRN-4 lowers pls

[@GrabinDragon018]

I don’t see it anymore on there website, Did they discontinue it ?

[@spookyindeed]

yes

[@user-fd7tl4xg6y]

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!

[@RJM1011]

@Joshua Bressel thank you for the advice. I not to sure about Adams arms kit because of the tension put on the BCG that causes wear due to the piston conversion. What branch of service were you in? I was in the Army. Hoah!!!

[@QarthCEO]

What is so great about a piston AR? Gas impingement works fine.

[@QarthCEO]

@Joshua Bressel If shit hit the fan, I'd carry a DI AR because I know I can find standard parts for it everywhere. As for reliability, even in the sand box I have never had a problem with DI reliability. I guess that wasn't an extreme enough environment.

[@QarthCEO]

@Joshua Bressel Very interesting. I guess I'll take the plunge and try one out. So do you think an Adams Arms kit would be a good start?

[@pd5156]

Here we go again.

[@kaiul2967]

The real HK416 OTB models can also allow you to shoot after being submerged in water. Normal DI M4s would blow up because water pressure due to blockage in gas tube and barrel. Something normal people wont ever need but elite teams like the SEALS do!

[@QarthCEO]

@@kaiul2967 I tried out the Adams Arms kit. Shoots fine and it really does keep the rifle clean. Happy with it so far.

[@tsafa]

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

[@mabs9503]

Super cool and would love to have one but dang the cost of entry is too high. Also, you're doing the 16" barrel again. Why? Just offer a 14.5 pinned barrel. Why does every single company who offers "lol it's a clone of a military gun but with a 16" barrel" not just give us an option? I have three ARs laying around right now that 'd have 14.5" barrels on them but no one offers a good 14.5 pinned option.

[@Dan-di9jd]

@@gordy505 It be slightly cheaper by about 500-600 depending. So the base rifle is $2000 range, and first thing you have to do is chop the semi auto thing off the barrel extension. Then you can buy a 416 carre&bolt and that be about 600 right there. Then you can buy a gas block for the 416 which will set you back about 300-400. Then you go put on the new gas block, chop the barrel, and permanently pin&weld the barrel. The barrel is stainless steel on the HK 556 but I don't think you'll find a chrome line one. Even the brownelles 416 profile barrel is melonite and bare steal. The actual 416 barrel, if you can find one, will cost you roughly 1500-3000 depending on the condition.

[@Dan-di9jd]

@@gordy505 Also, don't send your firearms to the IGF guy. He's a fraud. They busted him after getting about 30 complaints from people who say they sent him their firearms, and/or money, then never hearing from him again. The guy's name is Jayson Cotter.
