1st, please don't criticize. Yes I am bad. I am ROUGH on my guns. All of them. Can't help it. I climb trees and rock with my rifles flung over my back. They bang around as I run through the woods and through the swap and over the stream and under the trees. I get it, I AM BAD girl. But that is me. For the most part, my 527s handle my ways and all is well. This week, however; an issue occurred. I get to the top of a peak where the world is mine and no one, but God and I know what is what. I pull my 12 year CZ 527 in .223 from my shoulder and I decide to empty two magazines in record time. Shot 7, the bolt handle comes off in my hand. Really, WTH????? What if this was an emergency. I take out my iPad and YouTube has a video and the bolt is back together. I get home and realize my carbine in 7.62 has the same bolt. I inventory my other rifles and the 527 is the ONLY gun(s) I own where the bolt handle comes off. So.. I want an upgrade bolt. Suggestions on where I can a better bolt replacement?
