CZ 550FS 6.5x55 Issues
« on: July 23, 2017, 03:31:51 PM »
Hey guys,

My first CZ came in a couple weeks ago, and I fired it for the first time this morning but things did not go smoothly. I cleaned it prior to shooting. Out of 20 rounds about 3 out of 5 times cycling the bolt it would not be cocked. When it happened, there would be little resistance when pushing the bolt handle down, the cocking indicator showed nothing, and the gun would not fire. I made sure the bolt was absolutely all the way rear, but it made no difference. They only thing that seemed to helped was moving the bolt fast and very hard, but this did not solve it completely. Does anyone know what this could be?

I thought it was maybe the PPU ammo I was running through it, but it did the exact same thing with a few rounds of Norma Onyx, and also when it isn't loaded. I sat here a bit ago after cleaning and cycled it, and sure enough its still having the issue.

Took the gun apart to try and figure out what was going on. Got the trigger adjusted to where I wanted it, but the mechanism highlighted in the picture (sear?) still would not return to the upward position after cycling the bolt. If I touched it, it would. Used some spray gun cleaner and then cycled it about 20 times, and it hasn't done it again. Possible some grease or a metal shaving could cause a problem as serious as this?

Also, am I good to dry fire this quite a bit more just to make sure its functioning correctly? Did not want to over do it.

All I can say is that if you can 'fix' something by cleaning and lubing...

it wasn't broken.

How's the accuracy? What loads are you shooting?
I had the right to remain silent...

but not the ability.
