It’s Christmas in January for the 72nd Mech Bn of the Czech army. They have received their initial stock of these designated marksman rifles. Altogether, the line units will receive 350 units of these plus optics and accessories by the end of the year. These replace the Dragunovs. Photos posted by the Bn.

Holy Cow. Thanks for the pics!!
Hopefully theyll start making their way over here.

That's sweet...now where IS mine... 8) ;D
-
CZ needs to fix and fully support their x39 Bren 2 before I’d buy another one.

The way things are developing, it’ll be waiting for you on the new Eastern Front [emoji3]. The Czechs are ready to deliver surplus 152mm shells to the Ukrainian army. Seriously though, that will be something crazy to happen over there.
-
Very nice! Thanks for sharing the pictures.

I'm interested in the muzzle device and handguard, as both seem different from the standard Bren 2 BR.

Nice! Now, we can all hope together that BREN 2 production will begin in the US soon, if the political landscape changes.
-
Pretty neat how the BR Stock matches the magwell of the BR rifle.
Just like the Waffle Stock matches Bren .556 pistol and Carbines.
-
I wish it's better than 2MOA...
-
If we knew how many shots were used to make those groups, we'd get a better picture of true and practical accuracy. HK give the accuracy of the G28 as sub-1.5 MOA, but that's for a 10+ shot group. 5 shot groups are easily half that for the G28 and the MR308/MR762.
Point being that the more shots to a group, the more it'll probably open up. If the Bren 2 PPS did 2 MOA with a 10+ shot group, I'd consider that respectable for a DMR/battle rifle.
Besides, it shoots better than the SVDs it's replacing, which are probably fairly ancient and whose optics aren't as good as what's available for the PPS Bren 2.
-
Yup. That's an excellent point on how a group can open up between 5 and 10 shots.
Quick question, are the CZ Bren 2 Ms barrels Chrome Lined?
And, were the Original 805 Bren S1 & Ps1 Chome Lined as well?
-
IIRC, all commercial Brens have/had chrome lined barrels (also CHF), and I believe the Bren 2 BR and PPS have CHF/CL barrels. I believe that other modern self-loading sniper/DMR rifles like the SCAR 20 HPR and the HK G28 have chrome lined barrels that are cold hammer forged. That seems to be the general industry standard, even for precision self loaders.
Granted, I think that the MR762s here in the US can be had with or without chrome lined barrels.
-
Thank you for that info.
Also, how many rounds would you guess the Bren 2 Ms with the 8" barrel would be good for, also the Bren 805 Ps1 with the 11.5" barrel
I'm guessing quite a lot considering they are chrome lined?
I shouldve just asked about barrel longevity for the 8" and 11.5"
-
Not sure what CZ rates their barrels for, but I know that HK and FN rate their 5.56mm barrels for up to 15-20K rounds before they ought to be replaced. Granted, M4s with button rifled barrels (chrome lined) are normally replaced before 10,000 rounds, and even then they still often produced very respectable groups.

I got to digging around a bit and saw where a fellow on this forum had 19,000 rounds thru his 805 S1 with no malfunctions and no inherent loss of accuracy.
Sounds like CZ barrels which are Cold Hammer Forged and Chrome Lined are like that of FN and HK. Awesome barrels.

I'd recommend you focus on group size. When group size becomes unacceptable, that barrel is dead. For me, when groups get beyond 4 MOA or so, that barrel is no longer useful for my purposes.
If a barrel starts out at 3.5 MOA, it won't be good for too many thousands of rounds before it exceeds 4 MOA. If it starts out at 0.5 MOA, it will probably last a long time.
You can probably expect between 10,000 and 30,000 rounds out of a decent 5.56 barrel before rounds start keyholing. Less if you get the barrel hot. Much less if you get the barrel hot shooting steel jacketed ammo.
I've had a cold hammer forged, chrome-lined 5.56 barrel exceed my accuracy requirement of 4 MOA in only 6-7,000 rounds. Somewhere around 6k rounds, it jumped from 2.5 MOA to over 6. I shot 55gr Wolf and Barnaul steel case almost exclusively.

This is the continuing problem with CZ, though. There are no spare barrels available now, along with the general shortage of critical parts for the Bren 2 platform.
Replacement Barrels of different lengths and different calibers (say 6.5 Grendel, for example) would sure be nice, but so far, CZ has not obliged. Hopefully, some enterprising soul in the aftermarket will fill the void.
-
Has the top brass at CZ said anything about the overall lack of support? Have they even acknowledged it?
If so, Have they said anything about when they will address it?
I'm really curious about this.
Thanks.

I like the Bren but is it wrong to wish some of the surplus Draganov's could come over here? O0

Not surprisingly, there go the surplus Dragunovs….

The Chamber is chrome lined, the bore is not.

LOL
I guess the US SVD autists are going to scream bloody murder over that! Don’t fear, B&T has taken over US importation of the Hungarian SVD @ $6,500 a pop! Not bad for a 3 moa commie “sniper” rifle — if you’re selling!!

Lol, wow!! Only $6,500 for a out of date 3 moa rifle!!
Man, that's just ridiculous
