Launched in 2016, the Bren 2 was a significant upgrade program over the original Bren 805 rifle. In addition to being offered in both 5.56mm and 7.62x39mm with user-changeable barrels, the Bren 2 was both simpler and lighter than the 805. virtually every part of the rifle was improved, from removal of the 2-round burst and simplification of the fire control system to making the gas system more robust and easier to work with. The Bren 2 has been adopted by the Czech Army, as well as the Hungarian military, GIGN, and many other organizations.
Thanks to CZ in Uhersky Brod for inviting me to take a look at these and other firearms in their reference library! Make sure to check them out on Facebook and Instagram!
The CZ807/ Bren2 was developed in R&D facility CARDAM sro. in Czechia. They also developed civilian rifles system, series CZ600. Take a look at styling as a cue. https://www.youtube.com/watch?v=KyAQoGr9KwI&t=219s
“I’m Ian McCollum”
So you’ve been claiming for years – you got any proof of that?
There are rumors that Ian was born in Elbonia rather than the USA.
The family made it out by going “look at the zeppelin “ to a border guard, then slipping through whilst they were distracted
It is said that his original name was Col Willis Corto, that he flew the Gullfire over Kirensk and maybe Leningrad, and that he is one of a handful of survivors of Operation Screaming Fist, after the EMP debacle.
Some say that he sweats nitroglycerin, and that his index finger is a universal chamber reamer, but all we know is, he’s called Gun Jesus
Any chance on a video of the CZ reference collection/museum?
The 5.56 magazine is also marked .300 AAC.
With the adjustable gas port, it looks like a beautiful host for a suppressed .300 gun.
Shame that US versions could only be rifle length, though.
“The 5.56 magazine is also marked .300 AAC.(…)”
This seems like… potential hazard to me. What happen if one will shove magazine loaded with .300 AAC ammunition into 5,56 version and then attempt to fire?
No different than on any other magazine. Simply because the mag is marked with both calibers does not mean the operator doesn’t still have to use their brain.
A smart person who uses both calibers would have designated mags for each and distinctive markings to differentiate between them.
My P-Mags for 5.56 have the older rubber magpulls. The ones for .300 BLK the hard Ranger plates. Too easy.

There is something here.
The main hint of possible problems is the not very stable operation of automation.
As the number of shots increases, this becomes more obvious until problems begin.
In the M43 variant, this happens earlier, 5.56 later.
This is probably not very critical.
But the product is still raw.
I recall a video on MAC addressing failure to eject on an early Bren2 specimen in 7.62×39. This was in rapid fired semiauto mode. I did not follow the case further so I do not know what the outcome was. Even if the problem persisted, what does it mean? That there is not enough action for overtravel to dispense with recoil energy? Who can tell is perhaps only the designers/ testers.
An assault rifle is a compromise, actually a bad compromise. It can NEVER substitute for machine-gun. The auto-function may be retained for contingency, but the prime purpose of it is a semiauto only. Sure, AK and its derivatives are capable of full auto function till they burn and melt. But that is the only known design out there, rest of it cannot take auto-fire for a long period of time.
I recall a study conducted in Russia which indicates that mere 1mm of bolt overtravel past the fresh round head is enough. That may have been an extreme test. In reality you need at least 5mm to have action working reliably. Problem is that at full-auto the recoil energy from one round does not dissipate in ONE full cycle; it tends to accumulate/ aggregate. Designers are forced to make weapon light and short so let’s be ready for some negative impact.
As said so many time before – every engineering solution is a compromise. Is it an acceptable compromise? That is up to every individual user/ operator to answer.
Correction:
“That there is not enough overtravel for the action to dispense the recoil energy?”
instead of:
“That there is not enough action for overtravel to dispense with recoil energy?”
The stories about “compromises in firearms” I first heard from the staff of the plant in Izhevsk.
So they tried to explain their stupidity and crooked hands, which for 30 years prevented them from doing at least something worthwhile. LOL
Tell real operators (whose life depends on their equipment) about these “compromises” and find out where they will put them for you. Or at least they will tell you where to go for it. 😉
“An assault rifle is a compromise, actually a bad compromise. It can NEVER substitute for machine-gun. The auto-function may be retained for contingency, but the prime purpose of it is a semiauto only.”
Agreed to a point. The US Army realized that and replaced the M16 armed automatic rifleman in the fire team with an M249 armed light machine gunner. The Russian always realized that – that’s the original reason the AK was developed, to replace the PPsh-41 and PPS-43 in the machine pistol role. Then they realized it could replace the SKS in the rifle role. Easier on support and training to have one weapon. Of course, the RPK is arguably a glorified assault rifle, but my impression it is beefed up for the LMG role. Anyway, to me, an assault rifle combines the functions of a rifle and machine pistol and not a light machine gun
“(…)RPK is arguably a glorified assault rifle, but my impression it is beefed up for the LMG role. (…)”
Indeed this is so – RPK has stronger receiver, though it might be not obvious after just looking

Характерной чертой пулемета РПК стала обновленная ствольная коробка. Она почти не отличалась от соответствующей детали автомата, но имела усиленную конструкцию.
Longer receiver and thicker as well in the RPK. But never forget to look at the whole squad and its composition, as normally also at least one PKM machinegun is being issued alongside the RPK to give the squad automatic fire. Plus the also issued SVD rifle to give point target capability. The AK rifles are really only there to give close in fire power, self defense for the soldier carrying it and to defend the other weapons in the squad.
