Straight and curved 30 round L2 rifle and L4 Bren magazines. I think that the
UK
curved mags were designed to be more reliable in that the slight curvature more followed the actual curvature of a dual stack of ammo. So the theory goes! But curved or straight, they all seemed to work just as well. Additionally, the curved mags had a UK patent attached to them so they couldn't be pirated - much like the body mods and ejector systems for the L4 series of guns. SO....., if anyone purchsed L4 guns, they'd also HAVE to buy L4 mags, spares and barrels. That was the theory. But L4 buyers across the world who bought L1 rifles cheaper from
Australia soon found out that the
Canadian and Aust straight mags were just as good PLUS, Australia could and would sell them all they wanted and cheaper too. Same applied to new L4 barrels. Aust could make and sell cheaper than we could. Talk about cutting off our noses top spite our face!
I think I've told this saga several times.
