BRN-180 Review (Page 1 of 13)

Posted: 5/10/2019 5:03:36 PM EDT
The short and sweet of it is I am very happy with it, it looks to be 1 MOA capable (it was 1.5-2 MOA with bulk fmj), light recoil, light weight, massive hard on.

Through sighting it in and playing around with it today it went through 120rds flawlessly. Fit and finish is great as I expect from PWS. It’s not all sunshine and daisies however, there’s a steel insert where the cam pin rests in the receiver. This itself isn’t an issue but they’ve used a screw to hold it in place and covered the head in a rubber knob. Looks funny and bothers me a bit, I am going to ask Brownells if the rubber bit can be removed. The whole reciprocating handle is a bummer but doesn’t seem to get in the way and there’s no adjustable gas block but they did include a suppressed piston sleeve that has some additional venting drilled in. I removed the funky flash hider and replaced it with an FSC556 brake/hider.

I plan on having a recoil test against two other rifles, my PWS MK116 and a borrowed basic bitch mid length DI. I was thinking I’d run 10rds into a target at around 25yds as quickly as possible on a timer. I’d then compare group size and speed, if anyone has some suggestions on bettering this test lmk. So far it has a reciprocating weight advantage of 5.1oz against the DI and 7.2oz against the PWS, of course this doesn’t tell the whole story.

Ditch the buffer tube and put a side folder on it then it will be very nice.

Mine comes Mon/Tues. MCX folder and KNS adapter ready to go.

My first thought too, but after looking at it awhile, looks pretty good with the tube.

You are complaining about the rubber knob?

Dude think about it. Why is it there? Could it be because this is a side folder and doesn't use a stupid buffer tube and the rubber could be a added feature to stop the side folder hitting the receiver?????

[Last Edit: BRN-180] [#13]
Owners be advised..........

The dust cover could, not pop open when firing resulting in the charging handle hitting the plastic cover hard.

The cause could be design of dust cover or a strong engagement of the plunger on the dust cover.

Before you fire with the dust cover closed, hand cycle the cover open and closed many, many times.

This seems to polish the surface where the plunger meets the port and improves the opening action of the cover.

I'm not the only one that observed this (handle hitting dust cover). It has been reviewed as an issue.

I haven't fired mine yet but confirmed the issue with hand cycles.  After many cycles it gets better and better.

So far I like it.

It locks open and closed solid. I mean SOLID to an extreme.

Length of pull is short but you can add extensions (riser) to increase it up to 1 inch.

I am searching now for a slip on butt pad. One would be nice since the butt is very thin.

I really like my choice of a PWS lower. It is perfect and neat.

Excitement seems to be lower on the BRN-180 after the initial push.

Not for me.

It fact, FOR ME, the standard AR will be obsolete. For me the BRN-180 is superior.

There is nothing in the AR market that would ever get me to buy another one. I have a few and have lost most interest.

I am waiting now for a BRN-180 in 7.62X39.

People looking at a MCX carbine for something different should look at the BRN-180 first.

The BRN-180 is less expensive, less complicated and a better design.

I am hoping for some high profile reviews to come out soon. Nutnfancy, Mrgunsngear etc.

In Range has a new review up: https://youtu.be/wAHaF1jPxSc

I've always wanted a 180 type gun, but held off for the cost as a shooter of the Stoner or Daewoo with lack of spares and whatnot.

AR15 is obsolete compared to 180?  Based on what?
It’s better then the MCX and a better design?  Explain.. If you were going to spray diarrhea at least be able to clean it with an explanation

IMO

vs DI
Less reciprocating mass than a DI by 5.1oz (H2)
Piston vs DI points

vs MCX
The rails don’t break apart lol
Standard AR lower
Cheaper
Lighter

Less reciprocating mass doesn’t mean much.  I have an AR180 and it’s a pretty cheap rifle. Stamped and sheet metal.

AR180’s have very cheap stocks that break often. Thin barrel. Cheap sheet metal upper and lower.

MCX is heavier because it is built with a heavier barrel and is more heavy duty.  I haven’t seen any broken rails.  Virtus has a good trigger.  MCX is used around the world. AR180 was really only use in any numbers by the IRA.  Don’t let your bias get in the way.  I love the 180 but not enough to where I justify it by saying it’s better then a weapon that outperformed in in the late 60’s and 70’s

MCX can also be utilized with a standard AR lower, albeit with a conversion adapter on the receiver extension threads. Most would want to use one anyway, even for the BRN180 as it yields the benefit of a folding stock.

I’m not saying the MCX is a bad rifle, it did have to recall the guide rod assembly as they would break apart during firing. The BRN-180 has the weight and price advantage, I can’t speak to durability yet but it is built plenty strong

What? The only recall I've heard was for the 300BLK models being able to discharge unintendedly with one subset of 300BLK ammo. I've not heard of the assembly breaking while firing.

As to your weight complaint, compare the BRN180 setup to an equivalent MCX legacy setup. They will more than likely be close.

Same recall 2 different issues with the original carrier

Thanks for the article link, learn something new everyday. I would still lean towards stating "could possibly" over "would" as per the article it was a rather rare occurrence. That's semantics though.

I'd be genuinely curious to try a side by side comparison of the BRN 180 system to the MCX. I find the manual of arms control to still be superior on the MCX as it won't have the reciprocating charging handle and will instead mirror all AR controls.

That may be my anecdotal evidence coming through, watching it lock up like that.

Be advised:

This Sig MCX stock has been discontinued and there are just a few NEW in the marketplace left.  It is a nice option for the BRN-180.

The only place I found them left was at Optics Planet and they have just a few.

Code MEMTEN gets a 10% off OR code 2DAYAIR gets you fast shipping.  Your choice.

The recip handle is great. It is not a con for the design.

1. Acts as a forward assist. The forward assist on an AR-15 was added specifically because it did not have a means to fully control the bolt.

2. Acts as a bolt release when fired folded since the bolt release will be likely covered by the folding stock. This is a huge PLUS.

3. Great positive control of the bolt.

4. Provides ambi function of the bolt release. Bolt can be released both left and right. Something the AR-180 lacks.

There is only one down side and that is if you need to fire tight against a barrier. Not a issue 99% of the time.

I love the recip handle and Brownells promised different models of the handle soon.

A BRN-180 action with a non-reciprocating forward charging handle (ambi or selectable) would be pretty great IMO.

It is not a issue. People need to get over it. People always want something more, more, more. Many great weapons had and have a recip handle.

What's your point? That lots of other guns have reciprocating charging handles? Imagine that...
I didn't say it was an issue, I was stating my preference. I'm allowed to have a preference aren't I?
One could probably easily convert one to forward charging if I felt the need.

I’m not a believer that the forward assist assists anything

You should have a lower with an ambi release in 2019

The handle is in a better location than the SCAR so it’s not much of a concern to me

I hope they come out with a handle that will fold forward out of the way

The side of the rail/receiver is slick enough that a properly designed (HK style) folding handle would be very accessible unless you run a right-side folding stock.

A buffer tube isn’t a bad thing.
People don’t usually use side folders
Piston does nothing better then DI. That’s why DI is dominate. Also more accurate.
DI has way smoother operation then piston. Pistons tend to have a violent recoil (Hk416). Piston has more going and is a harsher recoil.

It sounds like you have sold yourself on un-truths.  If BS’ing yourself makes you feel better then rock on.
