Use the torx tool that comes in the cleaning tool kit to remove. Its very high quality and wont strip the bolts like some cheap torx bits you find at harbor freight and walmart.

CZ Bren 2 Carbine gas system explained: Running a silencer This video explains the carbine’s gas piston. I may go ahead and pick one up assuming I see an accuracy test. I’d expect 2-3 MOA with M855, but 77 gr SMKs should be 1.5-2 moa I would hope |

The only thing about the 7x62x39mm BREN 2 MS is the magazines, but I am learning to live with them - love this firearm. Better would be a lower that takes vz-58 mags so the bolt hold open/release is still useful.

Though even the high performance 3d printable thermoplastics available I'm aware of are no where near as strong as the material used in the original lower. Milling one from aluminum would be more comparable. Though there are some composite material printers available that can get a bit closer. Then again, if you only used cassette style trigger units, it would probably hold up alright. (Though whether those units will properly move the firing pin block out of the way and will withstand the bolt velocity difference between an ar and a bren 2 during unlock is a completely other matter.) Eta. How much heat the material can withstand will also be important here given it sits against the barrel extension where the take down pin goes through and will be under pressure from the magazine. A low heat material could possibly elongate at the takedown pin hole if you do a lot of high round count shooting/mag dumps which obviously wouldnt be good for reliability. It's certainly exciting to see all the new options people are coming up with though. |

+2 for a VZ58 magazine compatible lower. VZ 58 mags are light, aluminum, and hold the bolt open.
I also really liked the original 805 design with changeable mag wells but nothing productive ever came of it. I'd have no problem buying multiple lowers for different mag options in this platform. |

A factory folding Bren 2 stock sold on gunbroker today for $617.00. Surely someone is cloning this or CZ will manufacture them here for 922r? I basically NEED this stock. Sven!!!?

I would strongly suggest asking for a replacement or a refund. I'm pretty sure that wont be a problem on their end. I adore my brace setup. Its really comfy and provides a really nice cheek/chin weld with my 1.93 scalar works out. Super pleased. |

I'd buy that in a second. IMO that's what the US version of the Bren 2 carbine should have looked like. Not that the version we wound up with isn't nice, but it just doesn't have that something extra that the EU version has. That being said, I will still probably buy the US version eventually, but am hoping that CZ will come out with another model closer to the EU version to be sold in the US. I don't think they will, but I can hope. |

Update on my 9" 7.62x39, shot another 160 rounds today, 4 stovepipes. Used both gas valve settings. I sent in a warranty request form to CZ.
Question to you 762 owners, is the front of your ejection port getting chewed up? Mine is scratched all to hell and I am wondering if it is the same for all of you? I am attaching the video from my last range session from my previous post so you all can get an idea of what I am seeing. https://youtu.be/L-cUi9Aw11g The one thing you will see is my pistols ejection is very erratic, anywhere from 1-5 o clock. This happens with every flavor of 7.62x39 that I have tried, Wolf FMJ and HP and GT FMJ. |

Weird - the front of my ejection port is pristine, like the day it left the factory, and that's with Wolf, Tula, Red Army, and even cast reloads. Mine has been flawless. I agree - CZ needs to look at that gun.

This happens with every flavor of 7.62x39 that I have tried, Wolf FMJ and HP and GT FMJ. View Quote @tfdarchos Do the scratches around your ejection port look like they could be from the stovepiped cases? The mouth of the case will obviously ride against the inside surface of the receiver just in front of the ejection port, but if you have visible wear/scratches/etc... on the front side of the ejection port that is NOT common (at least in our experience). That second stovepipe in your video is unique; it looked like your bolt had enough velocity/travel to cycle back and grab another round (left side of magazine maybe) which usually indicates that the gas system is working properly. You might want to take apart and clean your bolt and carrier really well. Make sure that your ejector and spring are moving freely and not binding or dragging at all. We have noticed that these guns (and CZ's in general) come generously lubricated from the factory. The gas block/key/piston specifically, but again it might be worth looking at your ejector and extractor too. Last thing could be the magazine/spring/follower? Can you repeat this same stovepiping with other magazines? 762x39 in general is notorious for funky feeding around the banana curve in magazines. It seemed like your feeding issues happened early in the mag and the last 20 rounds or so ran better. |

Has anyone heard when the next round of carbines will be in, or if they'll sell 11" barrel assemblies?

I have been reading on forums are there any 922r concerns for the Bren 2 if I pin and weld the 14 inch and add an ACR stock? I am noob when it comes to this type of stuff.
