Secret to reinstalling CZ 527 bolt

I know it's only metal. I should be able to put this bolt back. No can do...sure would appreciate some help. Is there a secret to doing this? Been a long week, and this ain't helping. Thanks for any advice.:confused:

Should be able to press the bolt release (as removing the bolt) and it will aid in putting it back in place. There is no difficulty in putting the bolt in mine.

Oh man, is that frustrating, not being able to put a new gun back together! Been there, done that! :banghead:

I've never put a bolt into one of those guns. Have you recently mounted a scope on the gun? And if it a mauser-type bolt, is it possible that it is cocked, preventing the scope from going in?

Good luck, maybe some more CZ people can chime in!

PT...Yeah, I can press the bolt release...bolt goes in all the way except for the last 1/4 is cocked...and if that is the problem, any way to uncock without damaging it?

have you tried it with the mag out? It shouldn't be an issue but it may be.

PT...mag in and mag out...doesn't seem to make any difference:mad::confused:

well, I am stumped... unless there is some sort of bur on your extractor that is catching on the boltface... I just dunno, I can manipulate my bolt in such a way to prevent me from being able to install it at all, but nothing that will prevent it from closing the last 1/4 inch. hopefully someone more familiar with the workings of the action or who has had the same problem will come along... can you see what/where it is hanging up?

Sounds like the bolt isn't cocked. The rear lugs aren't lining up. I just got mine out and played with it to simulate what it sounds like you're talking about. To cock it I actually had to wrap up some pliers in a towel and hold the rear of the bolt to cock it.

Bolt should be cocked to install on a CZ. Did you do some adjusting on the trigger? Almost sounds like it might be catching on the sear that close from home.

PT...I appreciate you sticking with me through this...looks like the bolt had to be cocked...did that...went right in:D...Thanks folks, and a special tip of the hat to Blown6L and all are great!!

Glad you got it back together, I was about to chime in. Love my CZ527M, great little carbine!

FWIW: It is also possible to put the CZ-527 cocking piece on the firing pin upside down if you dissemble the striker assembly, and the bolt won't work in the rifle.

Note the cocking piece has a flat tab sticking off the rear edge.

That goes down toward the receiver tang.
If you assemble it "up" like the thumb cocking tab on a 91 Mauser bolt, it won't work.

glad you got it figured out man.... now what I am really curious about is how it wasn't cocked.
