CZ 557 bolt knob threaded?

[salsamigo]

Just checking if anyone knows if cz 557 range rifles have threaded bolt knobs?
If so what thread pitch?

Cant seem to find the answer on google.

Just emailed Cz asking the question.

thanks

Cz got back to me.

Turns out the bolt thread is M6x1.

The Area 419 Finger Groove Bolt Knob works perfectly!

Which one is it the CZ 457 bolt option?
Looks good and I need one for my CZ 557

yes, the same exact one!

Now my Cz 457 MTR and 557 have the same bolt knob.

That bolt knob needs a good circumcision or perhaps an exorcism? I guess it provides a good grip? Nice rifle OP, one is on my WTB list.

Yeah, not my cup of tea... probably functional, but esthetics are disregarded entirely.

Different strokes. I do find it much easier to run the bolt.

But the bolt handle being threaded means there's many other options.

On the topic of bolt clearance, I finally got around to mounting my Bushnell Elite 3500 3-9x50 to my 557. I used Warnes high QD rings and there was perfect clearance and just enough space to slip on the dust covers. Great rings!
