Thread: Advice & help please, brand new CZ 452 Misfiring?!

Agree with @7mmsaum +1

Viscous grease can accentuate any issues in the slowing of the firing pin and issues around the function of the bolt.

However, You might also want to try if firing a round and when getting a click, lift the bolt vertically until you hear the action re-cock and then drop back down ensuring its right down and try to fire again. If it fires- Then you've removed faulty rim fire ammo from the equation and its likely not locking the whole way down into place giving not giving the firing pin a solid contact it needs and therefore causing a misfire.

Just check this isn't the case as you can easily do this with a quick lift'n flick load when it hasn't completely locked downward into place.

I also have a LH 452 American and this so times happens when I'm doing the rapid timed shoot part of my card. Especially when they are new it's easy to not realise you've done it.

Hope this is your fix...
