For those interested, it appears that Bren 2 is shipping to distributors. There are a few on Gunbroker and the prices are reasonable. Who else is looking forward this?

But then again I haven't touched it since i installed it and turned it to the "off" setting (which i have drilled for a suppressor). |

Wow. I just read through several of these pages. Lots of fireworks.
A LGS near me just got a Bren M2S carbine (16” model with the long handguard). They want $2200. It would appear I would need the gas plug drilled for suppressed use. The trigger felt good, and I actually liked the bolt release inside of the trigger guard. My concern are some of the customer service issues I’ve read on this thread. Moreover, spare parts are another issue. I cannot locate anywhere that sells spare bolts, firing pins etc for this rifle. It would be nice if CZ had a forum here to address these issues, much like other AR manufacturers. Thoughts? Thanks as always |

The 5.56 16” carbines have a different gas plug than the shorter barrel pistols and it includes a suppressed setting. Don’t know if it’s the same on the 7.62 versions. |

CZ Bren 2 Carbine gas system explained: Running a silencer Also, I have a 5.56 carbine, my middle gas plug setting is marked “T”, and it’s port is smaller than the normal setting just like in the video. |

Quote HistoryOriginally Posted By themao: 5.56 nato. My understanding was there is a normal setting, adverse and off. There is a suppressed setting, but it'll still be overgassed with most 5.56 suppressors. I was shooting my carbine this morning with a Turbo T2 in the suppressed setting. It's pretty gassy with ejection at 2 o'clock. I'm going to send my gas plug to HBI and have them drill a smaller port in the off position. Mine is reliable, but you need to understand it's going to be a 3-4 MOA rifle with most ammo. I finally worked up a load with 77 SMK's and Tac that shoots 1.5 MOA repeatedly. |

TLDR version:
FTE issues start popping up from various members.(May/June 2020) Guns sent back, CZ says its because we didn't clean our guns properly. Guns malfunction again. Guns sent back, CZ doubles down saying it's bad ammo (lacquer cases). Guns malfunction again with brass/high quality ammo. Guns sent back, some of us get replacement guns. Replacements have same issues, CZ holds on to all Guns they have that were sent in (Sept/Oct 2020) CZ offers ro replace any 7.62x39 gun with 5.56, refund or you can wait for them to fix.(Oct/Nov 2020) CZ takes Months to write checks to people who wanted refunds, even longer to replace with 5.56 guns. CZ is terrible at responding to inquiries, no updates for months. HBI offers port drilling for suppressed use and high load piston spring. Fixes some users FTE issues. (Mine still has FTE with high load spring and port drilling) User on FB/reddit provides service to rework gas valve, reports are fairly positive.(summer 2021) CZ states that they are close to releasing fix as they feel they have found issue. (June 2021) CZ contacted again about release of the fix, says they have no idea when it will be released. (Sept 2021) Feel free to add to this timeline if I missed anything major. Ok, not so TLDR

No reports from the GIGN, but their version of the Bren 2 does have a few differences from ours. (Recoil assembly etc.)

My only reason for loosing some interest in it is because the commercial variant doesn't resemble the military model at all... The barrel is too heavy, the handguards are too long and it has the stock that is made for the .308 model. Unless I'm mistaken and the stock was an upgrade that went to all Bren 2s including the 5.56 military models? I just haven't kept up enough to know. |

I remember showing my buddy my Arsenal in 7.62x39 once. It was a cool gun.
He asked what the difference was between this and my Noveske .300 BO that was on the bench at the time. My answer? "Well, the Noveske is more accurate. And more reliable. And a lot lighter. And easier to reload, and find parts for, and mount optics on. Also, its ammo is more reliable than 7.62x39. And I have an upper I can swap in for 556 that has the exact same zero as the .300BO upper, so I can train cheap. And I reload the .300BO on my Dillon so the ammo isn't that expensive anymore really..." I sold my Arsenal the next day. |

To the people with the MS 2 Carbine 5.56 rifles, how is accuracy? I have seen reports all over the place of right at an 1" to 4" avg. That is quite a difference, found a 16" Carbine edition and considering picking it up but wanted to check and see what everyone was reportedly getting. Also want to confirm the 16" Carbine editions have a suppressor setting?
Also wanting to question there ability to run pmags? I saw Honest Outlaw video and he keeps stating he has issues with Pmags with his carbine edition |

I recently purchased an 11” 5.56 gas plug for my 14” x39 gun with the hopes that it would resolve the over gassing problem.* Well, I didn’t experience any malfunctions with it but the gun is still overgassed and ejecting at 1-2. It does have the HBI piston spring in it as well.
I disassembled the bolt carrier group to see if there was debris in the ejector channel as discussed earlier in the thread, didn’t find much if anything. Now I’m having difficulty reassembling the ejector assembly. To anyone who has done this: how did you reassemble the ejector spring etc? Does an AR ejector jig work on the Bren? Any advice appreciated *I swapped the gas plug from my 14” 5.56 Bren into the x39 Bren earlier and it ran well but it was slightly under gassed, so I figured the 11” 5.56 plug would be the sweet spot. |

Question for you 7.62 guys.
Does your gas piston adjustment plug have a hole at the end? See pictures. I was looking at the HB Industries site and noticed their customized gas plug does not have this hole. Maybe this is causing the feeding/ejection issues for 7.62 Bren2s? Ok, new to Imgur. Links are giving me fits.

I was looking at the HB Industries site and noticed their customized gas plug does not have this hole. Maybe this is causing the feeding/ejection problems. Yes, every Bren 2 (5.56 and 7.62) that is 11” and 14” has that gas vent hole. It’s unlikely it’s causing the problems by itself. An interesting observation though is that when I swap my 9” piston/gas valve assembly that has a 0.046” suppressed setting, it works perfectly on my 11” Bren2 suppressed and unsuppressed, but the 11” assembly requires a 1/16” suppressed setting and only works with a suppressor. |
