Rifle Chair has a pretty good video on the CZ 557, and points out the pros and cons of the rifle. The cons he mentions include the loose magazine which can result in misfeeds if the magazine tips due to pressure from the support hand, a rifle that is on the heavy side for a .308 carbine, the Picatinny rail is on the high side, although it does increase the clearance between the bolt handle and the ocular bell of a scope, the bolt needed some break in before it smoothed out, and the bolt release is inconvenient. He also mentions the tight headspace, which he equates with the fine accuracy his rifle demonstrated, 1 MOA at 200 yards with 180 gr Federal blue box, but acknowledges that chambering some ammo would be difficult as a result. If the bolt handle is not fully depressed, the safety won't engage since it locks the bolt in position. He bemoans the fact that the safety is not 3 position allowing the bolt handle to be raised without taking the gun off safe. He expressed concern that a novice might not be able to manipulate the magazine release safely since its inside the trigger guard; I think the location is good myself, one just needs to be cognizant of the fact that the mag release is inside the trigger bow. All in all, he said nothing that would prevent me from purchasing the rifle, and much that recommended it.
