$$$ Nine Benjamins.... Hmm... Almost think it may be worth just buying another complete pistol in the desired length unless you find yourself absolutely turned off by your 7.62 in its current state.  Although this option makes sense if you already SBRd your current kit.

I agree, $900? That's basically half the price of a whole new gun, and with that you can have a bunch more spare parts.

Thank you, Sir.

Agreed.  At that price point, I'd just buy a new gun for all the reasons you suggest.

Bren 2 Pistols

Hey guys just a bit of feedback on my 14 inch 7.62x39 Bren.

I have been after a next Gen 7.62x39 gun since SCAR came out.  So, when the Bren was introduced I was going to buy it. This is my 3rd Bren 2, my other 2 are, 14 inch 556 pistol converted into rifle and 8.5 inch SBR.  Absolutely love them both.  Almost forgot, I also have Bren 805 SBR’ed.  However, I was bit hesitant after reading all the negative feedback, thus the purchase was delayed.

To be honest, I have been collecting parts for 762 gun.  I was even able to score the receiver some time ago, 2 lowers, pretty much all the parts but barrel.  I have been buying  parts from CZ as they were available, including 922r compliance bits.

7.62  guns seem to be drying up, so screwed it, I picked up 14 inch pistol. It was immediately reconfigured into rifle.

1. ADCO permanently attach DA FS to bring the barrel to 16.25 inches
2  Installed 922r parts to insure full compliance
3. Ammo, Red Army and Military Classic from Wolf
4. This is based on only about 100 rounds but I feel pretty good about  this set up

Not sure what to expect and mixed feedback I brought the 14 inch 5.56 gun gas valve.  I don’t have pin gages, so the measurements might not be all that precise.

14 inch gas port data

1. ~1.17mm normal 556
2. ~1.70mm normal 762
3. ~1.30mm adverse 556
4. ~2.52mm adverse 762

7.62 gas valve function

The rifle run fine in stock configuration, set to normal gas port.  The ejection pattern was about 2 o’clock.  Little too overgassed for my taste, without failures of any kind.  The brass (should say steel) was able to clear the ejection port.  I did not feel any touching my fingers/hand.  There are no case marks present on the ejection port.

5.56 gas valve function

With 556 gas valve install in normal position the injection pattern was about 3  to 3:30 o’clock, almost perfect.  With gas port set to adverse, the gun was ejecting at 1:30 to 3:00 o’clock.  

Suppressed, Omega36M

Since the gun was overgassed in OEM configuration I didn’t run it suppressed.  With the 556 gas valve set to normal, the ejection was about 2 o’clock.  I would consider this slightly overgassed for suppressor application.  
I think with  1mm gas port the rifle would likely be perfect.

Please keep in mind this is my data, yours may be different.

yep - although I suppose it's a good sign CZ is producing kits, maybe we can get enough parts to have Mos Tek fab up replacement barrels.

I'd like to have MosTek build an 11" 300BO barrel without cannibalizing my 5.56 barrel for the extension and piston block.

20% off CZ USA webstore. If you want a barrel change kit, now is the time.

I have 14 inch barrel replacement kit on the way.  I will report back when it arrives.  I might trade for 9 or 11 inch 7.62 barrel/bolt kit or 16 inch 5.56 one.

There should be an extra page in the owners manual that explains the "-"  "1"  "+" settings but Zeebz is absolutely correct in his description.

why is this closed???

The replacement valve for the x39 guns has the same verbiage, and I see it as all settings are for unsuppressed shooting. The settings actually measure within .01" of the normal setting, which is not enough of a change for suppressed shooting. My hbi drilling was almost half the normal port size. You should measure your ports before assuming it is for suppressed use.

Can confirm the new 3 holes drilled on the Carbines in 5.56.  In "-" mode it wouldn't cycle steel cased, but would cycle brass but eject at 5 o'clock.  In setting 1 it ate everything and ejects around 2-3 o'clock and I didn't try the "+".  I also noticed the gas selector is stamped HB as well as the disconnector in the trigger group.  350 error free rounds on it's first trip and couldn't be happier.  It seems like the carbine is pretty well sorted out.   It also seemed to group better with 55gr over 62gr with an average of about 2.5 moa using a 3x prism at 100 yards.  One 5 shot group was 1moa.  Plenty decent enough for it's intended use.

Took my Bren 2 carbine to the range the other day, ran multiple mags without any failures / stoppages in 430 rounds fired using only the middle #1 gas setting. Mags tested included the D&H mags that came with the rifle, a CZ polymer mag, gen 2 pmags, gen 3 40 round pmag, D&H 30 round mag from PSA, Lancer 30 round mag, some old GI 30 round mags and Magpul D-60 drums.

Ammo used were my reloads, no accuracy test other than they all stayed on about a 4" area of a steel plate at about fifty yards fired off hand.  Like I said, no failures so it's a keeper. If anybody knows where I can get some spare parts like firing pins, springs, stuff like that, please let me know. TIA

Not sure if I'm brave enough for that web site, might try a little order first and see what happens...

My order was delivered but it took a while to ship because he had to source the parts from CZ. The company owner has been responsive over email.

Use the CZ USA webstore as a first resort.

At $1,399 it’s getting hard to resist the 8” Bren pistols on gunbroker.

Interesting he mentioned the upper being slightly changed for LE/Mil. It looks like the older model with the lightning cuts in the cupper.

That PDW has been around for a bit. Unfortunately for us, we'll never get one...

Looking good!  I actually like the way that stock looks more than the BR stock, honestly.

I think I saw in a FB group someone making US clones.
.
Honestly I have about zero interest in that stock, just thought it was interesting to hear about the rolling changes in the upper receiver.

Took the hbi gas regulator/piston combo out a second and third time, and suddenly the gun (9" 2S x39) is short stroking like crazy on setting 2. The first time I took it out it was slightly overgassed on setting 2 unsuppressed, and slightly overgassed with a can on setting 2, and undergassed on setting 1 with a can.

The second time I took it out it was acting severely undergassed on setting 2 with no can, and would only be reliable on setting 3 max gas with no can. Found that the piston was pretty much stuck in the regulator, and I had to take 2 hex keys to pry em apart. Talked to hbi and they sent over their gas regulator/piston combo for the 14" (more gas setting 1, same setting 2, less gas setting 3 vs 9" combo) to try and address the issues found the first time around.

Third time out, this time with the 14" combo, gun acted the same as the second outing, undergassed as hell on setting 2, short stroking and failing to feed. Checked the piston before and after the 3rd trip and it is smooth as butter going in and out, so that ruled out the piston being stuck in the regulator as culprit for the short stroking.

Will be trying again tomorrow with the oem 9" fix gas regulator and oem piston, and will also be bringing a spare op rod with so I have setups with both the oem as well as hbi high load spring. Previously with the oem regulator/piston combo I was slightly overgassed on the lowest setting. If tomorrow it suddenly short strokes with the oem setup on lowest gas setting I will have to fucking send this pos in to cz again.

I am starting to get worried that my gun has a gas leak or something as part of the barrel being a supposedly like new 'show room demo' barrel from cz.

tldr:

trip 1 (9" hbi combo) - overgassed setting 2 no can, overgassed setting 2 can, undergassed setting 1 can
trip 2 (9" hbi combo) - undergassed setting 2 no can, overgassed setting 3 no can
trip 3 (14" hbi combo) - undergassed setting 2 no can, overgassed setting 3 no can and can

I have the 7.62 in 11 inches. I never had any of the reliability issues as others but was getting 1-2 o’clock ejection. Way overpassed. With a suppressor and subsonic Brown Bear ammo, it was cycling on the normal setting so that proves it is way over gassed with normal ammo.

I sent it off for HBI industries to drill out the zero setting for a new “normal” and added their extra power piston spring. Seems to be gassed appropriately. HBI now offers a new plug with their own measurements, may give them a look.

Edit; 7.62x39 brown bear subsonic is extremely weak and typically doesn’t cycle at all. It does for me suppressed in the largest port size.

Just ordered a 11” model from locked & loaded for $1452 shipped

I think that the issue with x39 Brens is the ammo and the gas port balance.   The X39 ammo is all over the place, from under to over gassed.  That is why AKs are generally way over gassed to accommodate the variety in ammo.  With overgased Ak, the velocity of the carrier group isn’t as critical with respect to ejection port/opening.  The ejection port/opening for case to escape the action is rather large.  Yes, the overgased phenomenon will have negative impact on longevity of the parts.   In the Bren 2, the relationship of carrier group velocity to the ejection port size is much more critical and requires much better tuning.  Thus, when gas port is tuned properly for specific ammo, the gun will run just fine.  Now, this is proving consistency in ammo.  

If overgased the cases have the tendency to hit the front of the ejection port and bounce back.  Or, the velocity of bolt/carrier group is too fast to allow reliable ejection and loading the next cartridge.

If undergased, bolt/carrier group might not have enough energy to fully travel backwards to pickup the next cartridge.

Thus the struggle to properly tune the gun….

Any way around the massive fireballs coming from HBI's gas plug?

I have a 9" x39, and would like to stop/reduce the flames. I'm wondering if this is a result of a 9" barrel as opposed to the 11" or 14".

I think I'm gonna pull the trigger this weekend.  May get both an 11" 5.56 and a 9" x39, but if I have to decide on one, I suppose I'll go with the 5.56 b/c I don't want to get stuck with a gun that doesn't run.  But man oh man the x39 is so tempting.

If I get the 5.56 I'll get the 10.8 HBI handguard and SBR it since Form 1's are flying right now.  Throw the stock on, a light, and call it a day.  Not sure what can I would use with it.  Guess I'll see how the gas situation is first.

Dahlonega Armory has the 11" 5.56 for $1,424 right now.

Hbi made their gas valve have a relief port for gas to escape, the factory plug is sealed/doesn't have a relief port. No way to stop the fireball except switching to a factory 9" plug.

Dayum. My breaking price was always $1500 for a super shorty. Been waiting for a deal for a while now. If it was an 8" or even 9" 7.62 I'd be jumping on that.

So, what is the best option out there right now for a brace for the Bren 2?  It looks like the best options have all dried up.  What do you guys recommend?  

The CZ waffle stock

Brace, not stock.  Thanks.

Anybody want a deal on a 9inch 556 with a brace..unfired..hmu

@hanker71 PM sent.

i concur w/ mk4dubbin

CZ waffle stock
then swap out rear for Haga Design adapter
add tailhook





or check out: a3tactical
or HBI folder
or f5mfg

Yeah, that's what I would like to do, however , everything along those lines (waffle or ACR with adapter) seems to be depleted.  Maybe I just need to wait and be patient..... Not my two greatest qualities.  Thanks for the response.

SB Tactical  has a decent looking one and in stock - I'm sure you can find it cheaper elsewhere as well...

Or you could find a 1913 stock adapter and put some other 1913 brace on it.

Go cheap with the buffer tube adapter and brace, then SBR it.

Atlantic got me guys ordered the AP5 and AP5 K variant lol. Next purchase, probably tomorrow will be the Bren. Just can't decide between the 9" x39 or 11" 5.56

I wouldn't touch the x39 guns, there's just too many issues. If you're lucky you get a good one... If not, well...

Kind of where I'm at.  And I've already gotten rid of the other x39 guns  Been sticking strictly with 9 and 5.56 for both rifles and pistols.  Might as well keep that philosophy going.  Should have never sold my ACR.

Got my order from them today, looks legit.

1913 CNC Warrior brace /thread

These haven't been on my radar since they came out and people were talking about having problems with them.  
I was recently in a gun shop looking at a 5.56 version and I was talking to an employee about them.  Another customer butted in and said they arent good buys because they aren't being supported by CZ anymore because they're being discontinued.

I thanked him for sharing his insight on the matter and when he walked away, me and the sales guy looked at each other with a mix of doubt and curiousity if that were true.  The employee said hes pretty sure they're being used in Ukraine right now and that might have something to do with whatever that other guy was talking about, but he can't be sure.


So, now they're back on my mind, and I was curious how the 5.56 guns are reliability wise, and if there's any truth to them being discontinued.  I've always liked CZ guns but I feel like "support" from CZ has always been lacking as far as parts and stuff goes though.

So as far as issues with them that is strictly the 7.62x39 guns.  The 5.56 guns are supremely reliable.

CZ just did a drop of some parts for the Bren 2, but this is the first time I think we've seen a parts drop since they've been out.  CZ really got hit hard by COVID it seems.  And lets remember this gun came out in 2019 and then COVID hit.  I know people are mad at the lack of parts, but at least stuff seems to be moving a bit now.

They are being used in Ukraine right now and are getting a lot of hype because of their prowess over there.  As for the discontinued thing... some "ex CZ-USA employee" did an AMA on Reddit a few months back.  It was never confirmed whether he worked there or not, but a lot of people took it seriously.  He said they're discontinuing a ton of guns and Colt will be taking over all US operations for CZ.  Among those guns he said were discontinued were the Bren 2.

Now... CZ changes SKU numbers like its going out of style.  There is a Bren 2 PDW coming out with a different receiver (not sure if it's going to be a US release yet, though).  It's possible CZ is discontinuing current Bren 2 models in preparation to import the new receiver for the Bren 2 pistols so it can support the regular stock as well as the PDW stocks.  The PDW receiver is more angled near the top so the PDW stock bars can go in and out, where-as the current Bren 2 MS receiver is squared out in the same spot.  Here is a picture showing the difference.  Bren 2 MS receiver on top, Bren 2 PDW receiver on bottom.
