The ZB30/ZB30J are very similar to the Bren builds, expect for the striker setup is a little different. I know Ice House Manufacturing does Brens, so might be a place to start.

Just heads up, biggest thing with the ZB builds are finding barrels. The ZB26/ZB30/ZB30J barrels are all different in terms of gas ports and extractor cut outs.
The current ZB30J kits that are available do not have barrels and the last ZB30J barrel I saw sold for $2k+.

It seems like parts for the Bren are more plentiful. Do you know how Ice House Manufacturing's build quality is? Is there a ranking of the best Bren gun parts kits builders?

 

Len at Historis Arms I think has built a ZB-30 post sample in the past and builds a lot of Brens as well.

 

Few guys on weapons guild have. I'm currently doing one for a customer. No I don't have the interest to build more.

If its not available you can call them or send them an E-Mail they are one of the most professional Gunsmiths Company in Germany if it comes to WW Ordnance Weapons reworking Full Auto to Semi Auto including Export to the US.

 

Cant personally saw about Ice House Quality, but heard good things. Lol, no afraid there isnt a ranking system.

 

I had Bren MKI and MKII parts-kits assembled as semi-autos by Sean Prasky - Prasky Gunworks.
After almost two years building them, neither gun cycled, the MKI didn't fire a single round and the MKII separated cases almost immediately.
All trust destroyed with Prasky, I looked elsewhere for the fix.

Jim Kelly at Ice House volunteered to take on the challenge of fixing them.
I'll post here with the results. But my I obviously did due diligence second time around and the word on Jim Kelly is universally solid.

They look ok, they just don't go bang.

 

Jim is a great guy and builder. He has built a coupe guns for me including my Bren. Functions flawlessly.

 

Bowman have have a source on barrels ??
Bren builds are mostly abouts the striker setup however it may be different for your builds.??
