Product Spotlight: BRN-15 Upper Receiver Deep Dive

- Brownells Gun Tech™ Caleb Savant gives us an in-depth look at what makes our BRN-15 upper receiver unique. He's using the 16" barreled model as an example, but everything he says about it applies to the other BRN-15 barrel lengths as well. The receiver itself is a standard forged 7075 T6 aluminum "mil-spec" receiver, which means maximum compatibility with lower receivers and upgrade parts. The anodizing on the receiver and handguard is unusually high-quality, with a very even, smooth surface that actually has a slight sheen to it. (Don't worry, it's not glossy.)
The BRN-15's truly unique feature is its full-length aluminum free-floating handguard. It clamps to the barrel nut via two robust crossbolts that actually go THROUGH the nut to keep the handguard locked in place. Anti-rotation tabs further prevent the 'guard from twisting around the barrel nut, so any accessories mounted on it stay properly aligned. This is a very slim handguard so it fits comfortably in the hand. There's the customary full-length M1913 Picatinny rail on top that lines up with the receiver rail, and full-length rows of M-LOK® slots at 3, 6 and 9 o'clock. There are pairs of M-LOK® up front at the 1:30, 5:30, 7:30 and 9:30 positions. Plenty of open vents allow for excellent air circulation to cool the barrel AND make this handguard surprisingly lightweight.
The barrel nut is made of the same extra-strong 4150 chrome-moly-vanadium steel alloy as the barrel. The stress-relieved barrel has 1-7" twist rifling that'll stabilize all the common bullet weights, with a tough, wear-resistant black Nitride finish on the exterior. The gas block is NOT coming loose. It is secured by two screws protruding into dimples in the barrel, with a bit of high-temperature thread-locker to keep them from backing out. There's a standard A2 flash hider on the muzzle. On the Lightweight 16" barrel, it is secured by a lock nut, so remember to back off that lock nut first if you want to remove the A2.
The BRN-15 comes at an unusually affordable price for such a high-quality upper receiver assembly. The handguard alone could cost almost as much as the entire receiver assembly! You can get your BRN-15 upper complete, with a standard "mil-spec" charging handle and Brownells M16-type bolt-carrier group. Or you can get it without the BCG and charging handle, so you can customize it with components that fit your specific needs. - Sport
That handguard looks awesome! Thanks for the breakdown on the receiver group Caleb.
Great Video 💯 Thank You Brownells💥💥💥💥💥💥💥💥💥💥💥💥💥💥
I wasn't paying attention and thought it was going to be a BRN-180 and I was thinking where is the piston? It's still a very nice upper. I have a Daniel Defense 14.5 pencil barrel and it uses a standard size .750 gas block, it's still very light. I prefer the standard .750 size, but if you are buying a complete upper I guess it won't matter.
I was thinking the same thing looking for piston and charging handle guess that tells us the BRN-180 is selling well we all know about them
Wish you guys offered a ready 13.7 pin and weld
Looks like grey ghost is the oem which is great because they do have the one of the NICEST richest smoothest deep blacks. Similar to only zev, SOLGW and hodge
PWS is the manufacturer of these uppers and rifles unless it has changed. IMO one the best out there.

@@arlissyoung8899 the OEM rifle is made by Aero since they bought out Brownells, and that looked like an Aero BAR barrel nut. Makes sense they’d also do the standalone uppers.
You guys gonna drop the Brn-4 lowers soon?
Because the comments section must be insane, I will claim that a hot dog is a sandwich. Great video!
How are they priced so well
Do those screws holding that secure the hand guard go through the barrel nut? It looked like they interface with it somehow but I couldn't really tell
Liar!! You knew exactly what bits to have on hand,it’s a conspiracy I tell you!! JK good stuff!
do they make the brn-15 upper handguard in a split top version?
Are these available in FDE?
how accurate is it
Could a 6" (for example) muzzle device that is pin and welded count towards a 16" barrel length and allow for use of a silencer over that 6" section while not being an SBR?
Yes.
You can also permanently mount a suppressor to also reach the 16" requirement. A lot of integrally suppressed guns do this so you don't have to pay for 2 tax stamps.
Whats the gas system lenghts on BRN-15 uppers? I could not find that information on your website.
mid
What’s your nifty tool?
What’s the price?
Would've been great if the gas block was pinned.
Would've been more expensive too, though, maybe on a future model.
Cant wait for these to be discontinued in 2 years, like your entire Retro line that fell on its face due to poor availability!
I wish that you wouldn't spotlight items that are mostly out of stock!
They sell fast!
If you made gov profile in space metal for 50$ I would still be hesitant. Why use trash profile, oh, cheap trash.
Gov profile is trash, but cheap. Wtf.
The knurling on the dust cover rod does serve a purpose. It takes the place of the cir-clip. Knurling is a process that also adds to the original diameter. Its there to prevent the rod from passing through the hole. I use those knurled dust cover rods a lot b/c they are super easy to install or remove.
If you’ll sell it to a prohibited person they should be allowed to sue you
Lol what
Uppers aren't classified as firearms by the ATF. If you're going to talk shit, at least be knowledgeable.
