briang2ad, what features are you looking for? I assume you want to stay in 7.62, any other features of interest?
I’ve never shot a VZ58 but it looks pretty cool, lucky you!
I have the XCR-L that meataxe mentions in 7.62 and 5.56 (16” light barrel) and I think his feedback in this thread is good.
My wife and son both have the bren 2 11” pistol in 5.56 so I can’t exactly compare the bren to xcr in 7.62 but ultimately, the main differences are short vs long stroke, triggers, and the degree to which you can adjust gas.
Mig1nc mentioned that the XCR is kind of a boat anchor compared to the bren. Frankly, there’s truth to that. Keep in mind, I’m comparing a 16” light xcr to an 11” bren and the xcr does weigh more but not by too much. However, the weight issue IMO, is that the xcr, even with the light barrel is front heavy, due to the long stroke piston. In contrast, the bren is far more balanced due to the short stroke piston. Triggers are both good but xcr is crisp, geisselle-like, whereas the bren has a little mush and then crisp. The gas systems are similar in objective but the xcr offers more precise tuning, however, it takes time to get used to. Personally, bren is simpler on gas tuning. As far as overall shooting, the bren is slightly softer shooting.
We shoot all of these suppressed, one bren shoots a sandman, the other a velos. The xcr shoots velos. As these are low back pressure suppressors, we’ve not felt the need to adjust the gas settings between unsuppressed and suppressed. Ultimately, both shoot great suppressed but our experience is that the xcr is a little less gassy. I wouldn’t say that should dissuade you from the bren.
Ultimately, you can’t go wrong here if you got bren or xcr but it is unfortunate that czusa is bad on parts availability. There are 3rd parties out there that fill the gaps but don’t close them entirely. Knock on wood, our brens have been reliable but only time will tell.
