Are you thinking about the 557 model? The 550s do have the SST. One of my 550s (the 2005 model) has the old-style trigger and the other (the 2012 model) the new style. Actually, I think the "old style" has now been reinstated to the 2015 guns.I had a 527 in .223 and it was a great gun. I sold it because I have enough .223 guns. I wished they offered the single set trigger in their 550 model.
^ NO. INCORRECT Myth that needs to die. :banghead: I'm about as tired of seeing this one as I am the one that says steel cased ammo will destroy my 1911 extractor, ejector, blah blah blah.From post #10: "Also, the common, steel-cased x39 ammo uses bi-metal projectiles, which cause considerably more wear than copper jacketed ammo."
What? Is there any truth to that? I've never heard that claim before. I'd genuinely like to know because I shoot almost exclusively Tulammo through my AK
I bought mine, a .223 CZ 527 Carbine, in November of 2014. It has the new style bolt handle and the twist rate has been changed from 1:12 to 1:9. I have a CenterPoint 2-7x32mm scope (http://www.crosman.com/optics/scopes/adventure-class-2-7x32-mm) mounted with Warne rings (http://www.midwayusa.com/product/111233/warne-permanent-attachable-ring-mounts-cz-527-16mm-dovetail). There's no problem with the bolt handle interfering with the scope.Do the new ones come with the new bolt style?
I've been eyeing the CZ-527 in 7.62 for years now. I just wish they could take AK mags, or at least a 10 round magazine.
Bi-metal bullets do not do any more damage to your firearms than conventional copper jacketed rounds do.
The steel cases themselves don’t have any effect on the condition of the bore. The difference lies with the projectile – the soft copper jacket of the Federal ammunition simply doesn’t cause the same amount of wear as the bimetal (copper and steel) jacket of the Russian ammunition.

I read the article, which is very well written but focuses on ar barrels and a much higher velocity cartridge with higher pressure averages than 7.62x39. I think we can all agree that harder jackets would wear a barrel faster, but in a 7.62x39 you may not see the results in a decade, or even a lifetime.This test differs with that assertion.

Yeah I wish they took ak mags as well, but I think CZ wanted dependability instead of catering to the ak crowd so they used their own mag design
