CZ 457 Extra Spring...Where does it go?

[toasty]

Just getting into the CZ 457. I removed my cz 457 action to do a trigger job. After I removed the action, I have a spring laying on the ground. It is about .5" long and slighly bigger diameter than the factory trigger spring. I haven't taken anything apart and the magazine release spring is there, the bolt release spring seems to be working. I have no idea where it goes. Any ideas?

What model 457? There aren't that many springs - especially ones that would fall out when just removing the action. You say the the mag release and the bolt release are fine.

What about part 18 - Rear Sight Button Spring

Are you sure it fell out of this rifle? I’m always losing springs and screws, getting a replacement and finding it a year later.

Thanks guys. I have been through the exploded diagrams and all springs are accounted for. Not sure where this spring came from, but it is not from this rifle. The spring change went great. I put in a lighter spring and the trigger is now about 7oz. The spring on the right is the factory trigger spring, on the left is the spring I found.

I converted a CZ scout to a 22wmr. Bought the 22wmr barrel and stock from guys on here in the classifieds. Machined aluminum pillars for it and installed them. Added a Sightron s1 3-9 I got on clearance and into this whole build under $600 and have the scout stock and threaded 22lr barrel when I have a grandkids that needs to do hunter's safety.

Well, it is a shooter. Check out this 3 shot group my 11 year old shot at 100 yards with the Remington 33gr Accutip off a bench with a bag. My 14 year old shot a group almost exactly the same size with it as well so it is not a fluke. By far, the most accurate Rimfire I have ever shot and there has only been 15 rounds down the barrel. Did have 1 light primer strike, reloaded that bullet again and it shot just fine. Can a very light trigger spring cause a light primer strike?
