Well, I did it. Now what?

[Joelski]

So, I finally broke down and ordered a BRN 180s upper. My hope is to build an ACR style rifle that works better than the Bushmaster offering. The system seems to be reliable in what I've read since it's introduction and I honestly hoped to see more on this board. Looking for recommendations on folding stocks; I'm probably going to go with the 180M lower, so that will necessitate a 1913 attachment for whichever stock I do go with. Looking for any other bits of wisdom, advice, etc.. It's on backorder, so no idea when the upper will be in-hand. Lower is not back-orderable yet, so they must be a ways out from having any stock. Anyway, I have plenty of time to figure out this build, so dump it in!

[apmcdaniel]

If you want to go ACR - Dan Haga makes a 1913 adapter for the ACR stock. There only question is aesthetics - is the rail on the 180 lower long enough to look like that stock and adapter were designed to go together.

I just happen to have an ACR stock and DH adapter because I was considering Form 1 for my BRN 180. I will try to do a mock up for you to see. I just need to do it in a way that doesn't violate the NFA.

Dan Haga also makes a really nice 1913 adapter fort the Magpul zhokov stock, and it really does look good, like it belongs on there.

Sent from my iPhone using TapatalkThats the way I'm leaning, but I'd prefer the ACR stock. I just like the look of both the folder and the fixed version better than anything else.

I found a 1913 adapter for the buffer tube hole on a standard AR lower. I have a MI bullet lower just doing nothing.. might get to save a few bucks!

Don't worry about it. I don't want to get any of us sideways with the man.

How is the BRN 180 like an ACR? Seems arguably more like a SCAR to me, as the SCAR has a reciprocating CH, while the ACR has a non-reciprocating CH that can still be used as a forward assist. I would opine that the CZ Bren 2 is the ACR replacement.

Well, this was posted on Reddit this evening. I'm assuming the dude that posted did all of the due diligence. I've inquired as to what adapters he's used, will let you know ASAP. I'm pretty sure you would only need the Dan Haga adapter if you go with the BRN180 lower.

By the way - I think this looks great, overall. You are headed in the right direction.

That's pretty sweet. My last concern is weight. There is probably close to 2 lbs difference between that setup, and an MCX- style folder, or MI collapsible system.

Anybody here with an MCX that could speak to its durability?

BRN-180 is definitely on my list.

How do they fit on lowers? That's about the only complaint I've seen on them, is the lack of fit, to the point where they question whether they're in spec or not.

[SINNER]

I just reamed a lower and used oversized JP pins to correct a horribly fitting 180 upper for a friend. It was the third one he had received that would not fit any lower he owned. A few of the rail screw heads were also damaged straight out of the box. Neat design but needs QC help IMO.

[Joelski]

Mine was a little tight on the takedown pin, but otherwise, no worse than mating up a Noveske upper to a non-noveske lower.

Well, this fell together nicely. The 180 fit nicely onto the MI lower; not like they were made for each other, but tolerance on mine at least seems to be in the right zip code. Wondering if the spec was maybe adjusted an RCH with the latest batch. She's an incredibly smooth shooter. I've wanted a 10.5" in .223/5.56 forever, but hadn't felt compelled as the 300 blk checked most of those boxes. This gun is different enough, and an absolute blast to shoot.

Dang I like that a lot. I might have to do the same.

[Aragorn]

Yeah... that looks good.

I keep revisiting this thread and thinking maybe I should do one, maybe with an ACR stock, just to have something different. Or buy a Scar.

Or just.... not...

[Joelski]

After thinking about the ACR stock for a while, I decided it belonged on an ACR more than this type of gun. This has more in common with a PCC rifle, than a heavy battle rifle, and IMO, the MCX style folder capitalizes on that. This gun has been an absolute blast to shoot and stomp in the woods with. I'm still hesitant to install a flashcomp on it so I can run it suppressed; it's just so fun the way it is. I'll get around to it, but for now, I'm having too much fun just running it as-is. I've put close to 300 rounds through it so far which has me thinking I should slow down on the ammo consumption, but it's addicting!

Murdered-out. Just about optic ready.

What case is that?

One of them bulldog ones? Opinions

I’m looking for something like that, small and not stand out gun bag’ish looking

[Joelski]

It is a bulldog. It was tight with the SBR, but Mulva swims in it. The usual gig bag is way too big for her, but she can easily ride along with another rifle in those. I'm getting around to adding a MD for my can, but this is plenty of fun as it is.

Update: Ordered the 180M lower to complete the package. Thinking it might fit a little easier, but won't be upset if it's close to what I have now. This thing is rock-solid with no shake, shimy, or rattle anywhere!

[Joelski]

Got the 180M lower and built-up. The receivers mate perfectly, as expected. I’ve read about poor figment elsewhere, but these ones are perfect.

Sent from my iPhone using TapatalkHappy to. It's a different kind of purchase process; the guy only accepts a certain type of cryto, or a check that has 5 days to reach AZ. Needless to say, my fuggit circuit tripped and I wrote a check, so knowing what we all know about the USPS, I consider myself fortunate. He sells even more retro stuff like the OG side-folder and grip. If I were going that route (and I plan to build a retro lower as well), I think I will FedEx that check. [emoji1787][emoji1787]
