Absolutely awesome to see Brownells releasing 416 parts. Hoping to see the BRN-4 Lowers or maybe even a more modernized 416 lower with the Ambi selector to complete the package.
The last time they were is because it was actual HK parts that we purchased in a limited quantity, now we are manufacturing the parts so we can continue to offer them for the foreseeable future.
I likey. I have a Adams Arms Short stroke and I absolutely love it. I’m getting a long stroke next by PWS. If you’re in the market for a short stroke I’d definitely get this one, wasn’t available when I got mine.
The average user doesn't need cold hammer forged. Forging increases strength, but adds stresses into the barrel that affect accuracy when the barrel heats up
@@jonathansmith7306 I don’t really care what you think I need. If I’m paying 1500 dollars for an upper it better have a CHF chrome lined barrel, you can overpay for lesser quality if you want.
Its interesting to see how after all these years ar's have kinda settled on 1 basic format of reciever and gas system. Sure, theres many, many, variations that are better but the vast majority are still milspec upper/lower with a gas 16" barrel.
@@Spamsmoothie1701 They're selling shorter barrels separately. Not as a kit, though, so you'd have to buy all the components separate, but they're selling everything to make that.
All they need are machined bayonet lugs (which cost like $50 to make), 11" quad rails (which are... around), and to change the barrel profile to an M27 profile so a true M27 bayo lug would fit. I'm gonna use the airsoft bayonet lug on this. By the way, with this BCG, fostech binary triggers will work on this, so an HK416/MR556 using this BCG can actually do IAR things.
Nice, I have a Wolf A1 Upper and yeah, I freaked out when I heard of the bolt carrier tilt but I just had to buy a reinforced buffer tube that had the extra lip to eliminate any carrier tilt.
I have one also and I've shot it plenty with a standard buffer tube, never changed springs or went to an h2 either and I've had no issues whatsoever. The rear of the bcg is tapered so that it doesn't tilt and I think it's an over blown issue. The Taiwanese military t91s don't have tapered bolts and they don't have carrier tilting issues, what I have heard is that they get more buffer tube wear tho and that they just replace the buffer tube as needed (hence the knurled tensioner castle nut they use which makes doing so easier). So getting reinforced/antitilt buffer def isn't a bad idea but I also don't think it's an issue to be worried about.
Geissele copied the HK416 barrel nut when they made the first rail for it, thats why it looks so familiar, the barrel nut was so much better it became a new standard
I have a spare lower taking up space in my safe, I’d love to buy this upper, but it’s always out of stock with no back order. I think the 10.4 with a brace would look sick.
They have never been in stock and now they seem to have vanished as a kit. If the handguard is the issue, I think a lot of people will want the kit without it and buy a geissele
3:45 "the reason they do that is because there's no gas rings to add friction." The gas rings don't "add friction", they allow the gas to push the bolt forward while it's unlocking to reduce friction between the bolt and barrel extension. That's the effect H&K is trying to replicate with the spring between bolt and carrier. Someone teach this guy how an AR-15 works.
I may be wrong, but HK's uppers could fit on standard AR-15 lowers as long as the hammer profile was suited the 416 bolt carrier, correct? Would this upper need that same change made or will it run with whatever trigger is already installed in the AR lower? Plenty of people run triggers that don't have the necessary to work with the HK uppers, so is this something to keep in mind if a person wants to purchase a BRN-4 upper, or is it a case of a slight modification to the firing pin safety to function with a wide variety of triggers?
Is there any possibility that we could see a somewhat unique platform architecture from Brownells? What I'm thinking is an AR15-AR18 hybrid(or maybe 'even more hybrid' given the BRN180): essentially, it would be something like taking the BRN180 upper and adapting it with an AR15 style gas system. The internal recoil springs of the AR18 get rid of what IMO is the one glaring issue with the AR15, the buffer tube(well, one more issue, the fact that the butt stock attaches to the lower instead of the upper too, really creates unnecessary headaches; re: polymer lowers). It goes without saying, it just completely limits how you can design butt stocks in general, even fixed butt stocks, nevermind folders and such. And, on the other hand, the AR15's gas system solves the [IMO] main issue(s) of gas piston systems; the weight and the location of that weight(in front of the receiver). With the AR15 gas system, you would drop some weight, but, more importantly, you would also make the gun much more balanced with the weight being pretty centralized like the AR15. This is something I'm really interested in because I'd like to run a BRN180 upper on a KP15 lower, except for the fact that it results in a pretty nose heavy long gun(and I'd rather not ballast up the polymer stock for better balance lol). But this applies to a whole lot of potential options of course, such as a skeletonized folding stock, anything that doesn't weigh much of anything. Might be a bit of a pipe dream idea - but, to be honest, if anyone was to do it it wouldn't surprise me if it was Brownells! Seriously seriously seriously impressed with the different products you guys have brought to the market over the past however many years now, a LOT of cool stuff(...like that BRN180! lol)!
Piston AR's are a lot heavier, have sharper recoil and will gouge the upper in the bolt cam pin recess. With the rifle speed adj gas block, the internal piston is still the way to go with the ability to tune the rifle with the ammunition being used and leaves nothing on the table. For collecting, short barreled suppressed or something different, no problem with a piston..
Great content awesome review of the BRN-4 upper receiver Kit. the only downfall I have is the high price is there not a similar style system from Brownells that a poor could afford with a much lower price tag.. outside of that I think the BRN-4 upper kit is phenomenal, and is the next best thing to sliced bread... even though the price is cheaper then an original HK-416 it just needs to more affordable to the poors just saying... but I guess that is what makes it a high end high tech high priced AR-ish system..
You should update the stock status I ordered one only to get an email that they are not in stock nor may never be again. I didnt realize brownells adopted the optics planet model of coercing people into ordering products that are out of stock or do not exist.
The website inventory is a live inventory system, if it showed in stock when you ordered it, that is because someone beat you to the order being actually placed, in your cart does not remove it from the inventory system.
I had a CMMG conversion and a Sig 516. Gas piston AR uppers do not really bring anything but increased cost and complexity. Even with an upgraded bolt carrier does not turn an AR-15 into an AR-18.
You shouldn't turn an AR15 into an AR18, that's a downgrade in every way except maybe a folding stock (And you can do that DI). The AR18 ITSELF was a downgrade from what it was supposed to be, because they lost the gas system. People aren't buying HK416 clones because they're practical, at least I hope they aren't. If so, they're idiots. They're buying them because they're a historically relevant GWOT rifle.
@@superfamilyallosauridae6505 what you seem to ignore is that the AR-18 has been the basis of a number of military rifles. I don't know of anything besides the AR-10, the AR-15 and their derivatives that use the DI/internal piston for their actions.
