Has CZ fixed the issues with this caliber or is it best to avoid it?

Looking at getting the 9” variant but cautious it won’t run well out of the box.
 
I got one but it appears I am also clueless "to the issues" I am supposed to be experiencing?

edit: did a little google foo, its looks like earlier Brens had over gassed issues, failure to feed, eject. No such problems with my 11 inch/NR model.

Yeah, I’ve been kicking around the idea of a Bren again and was thinking about a 7.62x39 model but the numerous threads on US forums about reliability issues gave me pause. That, and the mag issue, too—I’ve got tons of AR mags and Bren 7.62x39 mags seem hard to find.

The 7.62x39 rifles typically come with a AR mag adapter sleeve for the mag well and the AR LAR 15 pistol mags in 7.62x39 are not too hard to find.

Mine (plus five mags) just arrived today...complete with magwell! Thanks for the tip!
 
My 2023 dated Bren 2 in 7.62x39 has seen just shy of 5.5k rounds since March…zero issues. 11” model, 3 position has system that is ported…my ammo has been 90% bulk Chinese corrosive (Type 56 ammo)
 
Zero issues with my Bren 2 x39 11". Not a high round count yet, to be honest, but nothing even resembling an issue so far.

I believe the gas valve issues were fixed in models made after 2022 or so.

I don't use corrosive ammunition personally (my range doesn't allow steel core ammunition, and almost all corrosive x39 ammo is also steel cored), but I've read enough of these Bren 2 x39 threads to know that the people who do shoot corrosive frequently highly recommend rinsing out the parts (all parts that can have corrosive residue, especially the barrel but all other parts as well) after every range session firing corrosive ammunition with one of the following:

- Hot water only
- Ammonia + hot water (dilute aqueous ammonia) 2:1 or 3:1 ratio - then rinse with hot water afterwards
- Ballistol + hot water mix (some people call this "moose milk") - in 9 or 10:1 parts water : Ballistol ratio

Different people swear by different solutions (both figuratively and literally) for dissolving corrosive salts. Your mileage may vary.
