Agreed! Since we’re talking about setting up a combination of non-standard parts only to be able to shoot .308/7.62 NATO ammo I seriously question why any discussion is taking place about modifying anything to use 8mm ZB/Bren mags just to fire .308???

When there is wide availability of the ZB39 mags which almost always reliably fit a std Bren receiver as-is, reliably hold and feed .308 cartridges, and require zero adaptation to do so I do not get the attraction of attempting a harder route to the same end result. Besides that, they also hold the full 25rds of .308 to the ZB26/30 mags capacity of only 20 cartridges.

There is no compelling reason in my mind to try and use the 8mm mags if all you are looking to do is shoot .308.
