♠ The Czech Vz58 is built from all new parts, on military machinery (most likely in a former military factory).
☠ The Century "VZ 2008" is built from cut up military rifle parts on reverse engineered receivers by minimum wage piece-workers.
Actually, both of them are made from a mixture of new and surplus parts. Czechpoint/CZ both admit that "some" of the parts are .mil surplus, so while the barrels and receivers may be new, things like your top cover and handguards are going to be surplus on both. And the Czechpoint/CZ receivers were originally singlestack, but were milled out here in America to accept hi-cap mags. Both Century and Czech rifles use a certain number of US compliance parts anyways, but because the Century uses a US-made receiver, you can use fully-original surplus 30rd magazines in it without running afoul of 922(r). In comparison, the Czechpoint/CZ rifles use American-made plastic baseplates (and followers too, IIRC), which don't feel to me quite as sturdy as the originals (let alone cheap-$13 for surplus mags, versus ~$40 for new mags).
Honestly, IMO the newer plastic furniture feels way too cheesy. The original composite furniture is extremely comfortable; the VZ-58 has one of the best pistol grips I've ever handled. On the other hand, the newer black thumbhole-style stock from Czechpoint/CZ is one of the
least comfortable stocks I've ever handled.
As someone who owns a Century model, and who's handled and sold the CZs, I'm not convinced that the difference is all that major. The Century certainly isn't finished as nicely, but it has the advantage of having a bayonet lug, and accepting surplus magazines legally. Plus it's got a threaded muzzle, so you can put whatever you want on the end of the barrel. Mine's been extremely reliable, and it shoots great. The real limiting factor in accuracy are the sights, and those are identical on both rifles.
