Your bolt knob upgrade
The original bolt knob that comes on the CZ 457 is tiny. There are many aftermarket bolt knobs for the CZ 457, we also make one (see Acorn Bolt Knob) that is much larger, but this one is in 7075 aluminium and comes straight from the CZ factory.
If you’re after an all metal bolt, this part will complete the look.
Dimensions:
M6 thread
height/length: 28mm
diameter: 21mm
This part fits on both left and right handed bolts.

Texture for this knob is great, heavier and heftier than the factory knob. Nice feel and touch with gloves. Can’t go wrong! I wouldn’t say this is a MUST HAVE, but I would say if you’re looking for minor upgrades at minimal costs. A worthy bolt knob is the way to go!
